08/05/24 – All kits that we have received a deposit for, and we have been able to contact the customer have been shipped. If you paid a deposit and have not been contacted, please check your spam folder, and/or use the website contact page to contact us. The remaining unsold kits have been put into inventory and are currently listed on the website as a purchasable item.

06/12/24 – Buy the end of the week, we will have attempted to contact, and ship, every kit that a deposit had been paid on. That leaves about 20 kits that we have received a deposit for, but the customer did not reply to my email. I will go back and make more attempts to contact these customers again next week. If you have paid a deposit, but have not yet been contacted, please get a hold of us.

03/31/24 – Machining production ended a week ago. I’m now in just assembly and shipping mode. We have 69 kits yet to ship and I’m getting to them as quickly as I can. I completely understand that the pace has not been quick enough for most people. If you have a vehicle down, or some other urgent need for a kit right away, please contact me through the website contact page and I will do my best to accommodate you. Again, I thank everyone for their patience.

03/17/24 – As usual, nothing progresses as quickly as I picture it in my head. So again, I find myself apologizing for missed date projections. Machining will wrap up the 1st part of this week. That will give me a little more time for doing assembly. Each kit takes approximately an hour to assemble, and I don’t trust anyone but myself to do them. I assembled 8 kits on Sunday, which seems to be the only day of the week that I have any uninterrupted free time. I will get kits assembled, and customers contacted, as quickly as I can. My normal work week is 65-70 hours, so there isn’t that much addition overtime that I can put in.

02/27/24 – Production is going well and kits are shipping. The current problem is, out of the last 10 customers I emailed to tell them that your kit was up for shipment, I only received 2 replies. These are customers you have paid the $100.00 deposit, so they are not super old sign-ups on the waiting list. I guess I will have to start trying to get a hold of them via telephone. Please keep an eye out for an email from me, and please respond as soon as possible. The longer it takes me to get a hold of people, the slower the process goes. For those who are interested, there are also updates and pictures of the CCV production on the G.A.S. News webpage.

02/04/24 – We almost met our goal of shipping the 1st kits last week. The major reason for the recent delays has been the installation, set-up and calibration of a new to us, DCC CMM (Direct Computer Controlled Coordinate Measuring Machine).  We wanted to have it set up, fixtures made, programs written, and operational before the start of CCV production. This new machine allows us to get much more detailed dimensional information on the machined parts as they come out of the CNC machines. We can now take a part out of a CNC mill or lathe, load it onto the CMM fixture, run the inspection program, and within a few minutes, have the dimensions of every feature on the part, accurate to plus or minus 0.0001 inches.

The CMM is now all set -up and programed, and the 1st parts came off the line last week. Shipping of the 1st kits starts this week and will continue through Feb. We decided on a production run of 120 kits this time. That is twice the number we have run in the past. I think we have around 85 of those kits spoken for, so there is still time to add yourself to the list and pay the deposit.

You will be contacted when your kit is ready to ship so that you can pay the balance due. As usual, I want to thank everyone for their patience.

01/14/24 – As usual we are behind compared to where I expected to be at this time. We have the CCV parts currently in production. I had hopped to be close to the end of production by now. There are 25 separate items to machine and it takes time. We purchased a new machine that had to be gone though, aligned, set in place and hooked up. That pushed us back by approx two weeks. Shipping of kits will still start this month, just later then I had hoped. If you would like a kit, but have not signed up on the waiting and paid the $100.00 deposit, there is still time. Not all of the kits in this production have been spoken for yet.

11/05/23 – We will be taking deposits for the next 30 days for the 4th production run of the G.A.S. CCV Kit. You must be signed up on the waiting list and have made the $100.00 deposit in order to purchase a kit. Finished CCV Kits will be shipped in the order that you signed up on the waiting list. We are currently contacting customers on the waiting list, to inform them of this updated deposit requirement.

10/18/2023 – The next production run of GAS CCV Systems is beginning this month. Over the next few weeks, we will be contacting via email everyone who has signed up on the waiting list. This is to get a count of how many of you are still committed to purchasing a system. That number will determine the quantity of the production run.

11/29/22 – It’s been a long while since I’ve updated. Due to lack of staffing the CCV project had been put on temporary hold. As of right now we have about 12 kits left over from the last production run. I will be contacting customers on the list and getting those shipped out. I will then asses the current inventory of sub-assemblies to determine which items will need to be manufactured to complete some more kits.

01/04/22 – Again I’m very sorry for the slow execution of getting these finished and shipped. There are a multitude of reasons for that but I don’t want to look like I’m just making excuses. The bottom line is that we now have all of this production run assembled and ready to ship and we are currently contacting customers with instructions on how to pay the balance. We are shipping kits as the payments are made.

09/13/21 – We have finished the machining of the M54 CCV Kits. We will start assembling kits and contacting customers this week. We will be contacting customers and shipping kits in the order that you signed up on the CCV waiting list. If you are not on the beginning of the list, please be patient. We are short handed and it takes time to perform all of the detailed assembly required on the kits. You will be contacted as soon as we get to your place on the list.

09/08/21 – It looks like we will be finishing the last of the machining this week. The plan is to start assembling and shipping kits next week. Thank you all for your patience.

08/18/21 – The three largest and most machining intensive components are finished. We are currently getting caught up on low inventory levels of our other products, and plan to get back on the CCV the middle of next week. Hope to be shipping kits early September.

07/31/21 – GAS CCVs started the 2nd half of this production run last week. We are producing 60 more kits. We still have some open slots, so I will keep the registration waiting list open for a while longer. If you want a kit, please use the “Waiting List” tab to sign up. Most of you that are already on the list have paid your deposits. If you have signed up and have not made a deposit yet, you might want to do that to guarantee a kit will be held in your name.

07/06/21 – Here is where we currently stand with GAS CCV production and shipping. We have slowly been shipping our current inventory and we are now down to six complete kits left. Contacting people has been very difficult because approximately two out of every three customers that we try to contact from the list never reply. I have spent too much time attempting get a hold of these customers trying to make sure that we aren’t leaving anyone behind in the shipping order.

It’s now time to run more production on the kit parts that we are running out of. Since it’s impossible to tell how many kits to make by using the number of people on the waiting list, we need to go back to the method we used for the past two production runs. Going forward we will be taking 20% deposits on the kits which will separate out the customers who are serious about making a purchase. We have approximately 150 customers on the list still waiting for a kit. In the next few days we will be contacting those customers via email to determine who is willing to commit to a purchase by putting down a deposit.

The deposits will accomplish two things. 1) It will give us a head count on how many complete kits we will need to produce. 2) It will force us to commit more time toward finishing the kit production and getting those kits into customer’s hands.

For the past year we have been short two people and have had no luck filling those positions. This has made it extremely difficult to allocate time to the CCV issue, and since no one had paid any money up front it was too easy to put out other fires instead of focusing on the CCVs. Even though it will still be difficult with the current staffing situation to focus on the CCVs, once people have paid deposits it adds a whole new level of urgency to the situation.

We will need to put a cut off date on accepting new customers on the waiting list and taking deposits. As a “heads up” to those customers that may still be interested in a CCV kit from this production run, you will need to be on the list by 07/31/21 and pay a deposit once you are contacted.

Again, I would like to extend my sincere apologies to everyone who has been patiently waiting for a kit and thank you for believing so highly in all of the engineering that went into this CCV system design. I would also like to thank all of our previous CCV customers that took the time to contact us via email and those that left wonderful feedback on the website CCV page. We don’t solicit feedback in any way. All feedback that you see on the site has been proactively provided to us by very happy customers.

02/28/21 – CCV kits have been shipping on and off since Oct 2020. I have been contacting customers on the list 15 at a time but only about 30%-40% of people are replying to the emails. This is causing extensive delays in progressing thru the list. I have to follow up multiple times before I move farther down the list trying to confirm whether the customers are missing the emails or just no longer interested and not replying. If you think you signed up on the list prior to August 2020 and have not received an email please check your spam folder or contact us to verify your place in line. Currently we plan on filling the orders for everyone on the list that wants a kit. There is a very good chance that this will be the last production run so if your are interested in a kit I suggest that you sign up soon. Even at $500.00 this product is not really profitable for us and we are reluctant to raise the price any higher.

10/01/20 – Progress on assembling and shipping CCV’s is going well. If you are one of the first 50 people on the waiting list you should be contacted within the next few weeks.

09/15/20 – We are currently contacting and shipping CCV kits in groups of 10 as I can get them assembled. Once we get to your group you will be contacted with payment information. Once the payment has been made your kit will ship within 1-5 days.

08/30/2020 – We will be finishing the rest of the CCV machining this week so we are going to start contacting customers on the waiting list. We will be contacting customers for payment, and assembling CCVs, kits in groups of ten. The kits take quite a bit of labor to assemble so we will probably be able to process around ten kits per week. Once we have finished assembling and shipping the fifty kits we have produced we will immediately start production on the rest of the kits.

08/09/2020 – Spent the past three weeks machining our normal products to prevent running out of our bread and butter inventory. As of Monday we are back running some CCV parts again. We are on the home stretch now. 1st image is what has been machined, 2nd image is what is left to do. All of the parts, except one, that are left to make are fairly quick to machine. Thank you everyone again for your patience.

07/11/2020 – I’m sorry for the lack of updates, I’ve been extremely busy. The Vacuum regulators have been finished for a while. That was the most machining intensive part with 3 setups, 18 separate cutting tools, and 81 different machining operations. We also finished a couple of vacuum fittings. The last two week we have been getting caught up on manufacturing cam tool kits and monoballs, both of which are very low on inventory. Next week I will post a picture of the finished parts and the ones that still need to be machined. Hopefully by later next week we can get back on to finishing the rest of the CCV parts.

06/14/2020 – We got a late start on setting the vacuum regulators which is last of the four major components. It got set up over the weekend and we will start machining them on Monday.

06/07/2020 – The 3rd of the four major components is finished. The 4th starts around Tue of next week. Then there are a lot of little pieces to make.

06/03/2020 – The 2nd of the four major machining heavy components is finished. Thursday we start on the 3rd and hope to start the 4th around the 1st part of next week.

05/31/2020 – I ended running all of the stock we had for the Oil Separators which made 75 pieces. I’ve since switched over to the 2nd of the major components which is the Main Base and I hope to have 50 pieces finished by the end of day on 06/02. I hope to be able to start the final two main components, the Vacuum Regulator and the Filter Housing Mounting Base by the end of this week. They run in different CNC machines so we should be able to run both at the same time.

05/17/2020 – Here is the new production plan….. In the past we have made runs of 50 kits. The plan for this 3rd run was to make 75 kits based on the number of people that signed up on the waiting list. Since we started machining kit components, that number has grown to close to 100, although I’m sure that there are a number of duplicates on that list.

Since the four largest main components of the kit take so long to machine I decided to break production of the those 4 large components up into 2 runs of 50. The smaller parts we will still run a single batch of 100 each. This way the 1st 50 people that have been waiting so long won’t have to wait until we have all 100 kits completed.

Starting on Tues 05/19 I will have some much needed help in the machine shop which should speed things up. We currently have a few of the small parts finished, and 1 of the biggest parts, the oil separator, we have the 1st fifty almost finished as well.

Again, thank you all for your patience!

05/04/2020 – The 3rd production run is in progress but moving slowly. Due to the COVID 19 virus we are under a “stay at home” order here in Michigan. I am currently trying to keep everything running here solo which means there isn’t a lot of time in a given day for running CNC machines. Hopefully things will change here is a few weeks for the better. I will update this tab on a regular basis as to the progress made.

For those that our familiar with the past production runs and pricing, I’m sure that you have noticed a price increase on the current kits. This is not something that we wanted to have to do. Unfortunately, the past productions runs have barely been profitable for us at the $500 price point. The are 25 separate parts that need to be fixtured and machined, which includes 40 separate machine programs, and 26 separate cutting tools. After all of the parts are machined and quality checked, there is an additional 80-90 minutes of skilled labor required to assemble each kit. Finally, each kit is tested for proper vacuum regulation pressure and operation. We had to make a decision on whether to no longer manufacture the kit, or raise the price to something that makes it worth our while to produce.

Because customers have been so happy with the performance of the kit, and indicated that they felt the kit was worth well more than the previous $500 asking price, we decide to keep making them. Based on the last three years of inflation alone, the price should have increased to $600.00. We think that $639.00  is still a really good deal.

Does the G.A.S. CCV replacement System come with everything I need to install it?

Yes. All the components and hardware are included. The kit also includes spares of critical hardware and o-rings in case something is lost or damaged during servicing the CCV. This way you won’t be left without a vehicle while waiting for spare parts.

Does the G.A.S. CCV System replace all of the failure prone plastic hoses used by the stock BMW CCV?

Yes. The two plastic upper hoses are replaced by a solid aluminum manifold and the lower drain hose is replaced by a larger and very high quality reinforced rubber hose.

Is the G.A.S. CCV System hard to install?

The system can be installed with or without removing the intake manifold from the engine. If you don’t remove the intake manifold I would put the difficulty factor at 5 on a 1-10 scale. If you do choose to remove the intake manifold the job would be about the same as replacing the OEM BMW CCV and I would raise the difficulty factor up to a 7 or 8. On some models the OEM CCV can be removed by just removing the throttle body without the need to remove the entire intake manifold. In that case I would give it a difficulty factor of 6.

If I decide not to remove the stock CCV from under the intake manifold when I install the my new G.A.S. CCV will the old CCV still be connected and cause problems?

No. Even if you do not physically remove the old BMW CCV from the bottom of the intake manifold it WILL NOT remain connected in the system in any way. The only draw back to leaving it in place is the few extra ounces of useless weight you will be hauling around.

How long does it take to service the CCV during an oil change?

Removing the CCV Vacuum regulator and oil separator adds about 15-30 seconds compared to removing the stock oil filter cap. Cleaning the oil separator by rinsing it out with aerosol brake cleaner adds another approximately 3-5 minutes.

What if I have my oil changed by a service shop, how will they know how to remove and clean the CCV?

The G.A.S. CCV System includes a laminated glove box sized instruction sheet that you can give to your service technician.

Can the G.A.S. CCV fail in a way that could hydro-lock the engine and cause severe damage like the OEM BMW CCV system?

No. With the OEM BMW CCV if the plastic tube between the CCV and valve cover failed, vacuum would get applied solely to the oil sump drain back hose, which would cause oil to be sucked out of the oil pan and directly into the intake manifold which could result in hydro-lock. With the G.A.S. CCV system that plastic hose is replaced by a two inch long solid aluminum manifold. It cannot fail in the same way as the OEM system.

Will the G.A.S. CCV System cure my excessive oil consumption problem?

Yes and no. The G.A.S. CCV will remove more oil from the engines blowby gasses than even a brand new BMW CCV unit. To the extent that your oil consumption is caused by a failed stock CCV, the G.A.S. CCV will eliminate that consumption. The G.A.S. CCV is not a cure for worn valve seals and piston rings. The amount of oil consumption reduction will be vehicle dependant.

Will the G.A.S. CCV pass emissions inspections?

That depends. The G.A.S. CCV will outperform the OEM CCV in smog testing, so if your state just checks emissions you will be fine. The only state that we currently know of that may not pass the G.A.S. CCV during a “visual inspection” is California. This is because the G.A.S. CCV is not “CARB” certified.

Are replacement parts available for the G.A.S. CCV if something needs to be replaced sometime in the future?

Yes. All the CCV components are available as replacements parts. The only wearable components in the system are o-rings and the silicone vacuum diaphragm. These should last a long time and are inexpensive to replace.

The OEM BMW CCV causes lots of problems in cold weather because of moisture freezing up in the vacuum regulator and drain back path. Will the G.A.S. CCV be better in cold climates?

Yes. The G.A.S. CCV will be MUCH better in cold climates. Unlike the OEM CCV, the G.A.S. CCV body is heated by engine oil. This means that once the engine and CCV are up to temperature all of the moisture in the CCV that comes from starting an engine in cold weather will get evaporated off and only the recovered oil will be left to drain back to the engine sump.

Will it be a problem if I live in a very cold climate where temperatures remain well below freezing for days or weeks at a time and my driving consists of mostly short trips?

It can be. Depending on ambient temperature the engine my need to be run as long as half hour or more to get the oil separator hot enough for a long enough period of time to evaporate off all of the moisture. If you take several short trips in a row in very cold weather it’s a good idea to take a longer drive or leave the car idling for 15-20 minutes after a short trip.

I see the G.A.S. CCV still retains the drain back hose to the oil pan like the OEM BMW unit. What keeps the G.A.S. CCV drain back hose from clogging up like the stock BMW one?

Several things actually. First, the G.A.S. CCV does a better job of removing the carbon based crud from the blowby gases and trapping it in the oil separator where it gets washed out as part of your oil change procedure instead of ending up in the drain back hose. Second, the extra volume of clean oil that gets removed from the blowby gases by the secondary oil separator helps to wash down the inside of the hose. Third, the gooey white emulsified sludge that can clog up the hose in cold weather with the stock CCV doesn’t happen with the G.A.S. CCV because it runs at engine temperature which turns the sludge back into oil. Forth, the drain back hose can be washed down with aerosol brake cleaner to rinse out any accumulation in the hose, including the 90 degree bend at the dipstick tube.

I have a supercharged M54. Will the G.A.S. CCV Kit work with forced induction?

Not the current version. If there is enough interest we will make a forced induction option. The design parameters have already been worked out and it’s very doable.

I’ve seen forum post suggesting I can replace my BMW CCV with a $5.00 PCV valve and a couple of hoses. Can I?

You can in the same way that you can replace your brakes with a water pump. Both your brakes and your water pump serve an important purpose but a water pump won’t stop your car and a set of brakes won’t circulate your coolant. The BMW CCV system and other manufacturers PCV systems work in completely different ways. The BMW CCV regulates pressure in a closed crankcase and a PCV valve regulates flow in an open crankcase.

If you replace the BMW CCV with a PCV valve it will always be operating in one of two modes. When the total quantity of blowby gases generated by the engine is less than the flow regulation rate of the PCV valve, the crankcase vacuum will increase until dirty outside air starts getting sucked past the engines crankshaft seals. When the quantity of blowby gases generated by the engine is greater than the flow regulation rate of the PCV valve, crankcase pressure will build until either you blow a main seal or the valve cover. Both of these situations are obviously very bad for your engine and wallet. This is basic physics 101 as it relates to flow and pressure.

Regarding the PCV valve question again, I’ve read that the high crankcase vacuum created by connecting a PCV valve to my BMW engine will reduce oil consumption. Is this true and how much vacuum will the G.A.S. CCV generate?

Possibly. There seems to be quite a bit of anecdotal evidence out there to suggest it’s true. The problem is, as pointed out in the answer to the previous question, the full manifold vacuum provided by a PCV valve will exceed the sealing capabilities of the engines crankshaft seals, resulting in dirty air from underneath the vehicle getting sucked into the engine and probably completely destroying the seals in the long term.

The current version of the G.A.S. CCV generates 30-40% more vacuum than the OEM BMW unit (approx 0.8-1.0 inHg / 0.4-0.5 PSI), but far, far less than the full manifold vacuum provided by a PCV valve (up to 20 inHg – 9.8 PSI). Our testing shows that the seals start to leak somewhere around 10 inHg – 5 PSI of vacuum.

Will the G.A.S. CCV system be available in a black anodized finish like what’s shown in the CAD models?

That was the original intent but there ended up being a couple problems with that idea. First, all the pockets and passages in the oil separator and vacuum regulator cause air pockets which would prevent those two parts from being able to be run through a commercial anodizing line. Second, is the cost. The number of parts in the system would probably add another $50.00 to the cost of the CCV kit. There is a possible future option if there is enough customer interest. We could anodize the two problematic parts in house where we can minimize the problem of air pockets and send the other parts out to a commercial anodizer since we can’t handle the total volume of all the parts in house. The black anodized finish could then be offered as an option for those willing to pay for it.

Does the G.A.S. CCV have a warranty?

Yes. The G.A.S. CCV has a 5 year warranty on everything but the o-rings. Since o-rings can be damaged by mishandling them during cleaning we warranty them for 1 year. Individual o-rings and complete kits will be available at low cost.
