G.A.S. CCV Replacement is in early release!

Looks like there's quite a few seals to make sure are in place on re-assembly.

My first thought: I had a catch can, it sucked. I hated having to remember to empty it all the time.

My second thought: This design is almost exactly how the OEM BMW M56 CCV operates that is built into the M56 valve cover. Notice the zig zag passages leading to the CCV diaphram chamber that also drains oil back into the motor:





I left my catch can installed after I installed the M56 valve cover and after a week the catch can was still empty, so the design works.

This GAS product could be a real nice easy solution for all M54 cars, and would save the effort and expense of finding either a used M56 valve cover and associated parts or buying new for now over $700....

All M54 not located in California that is. I'm convinced a smog guy would call out this solution in a heartbeat if they will ding me for a stock looking BMW intake.

It's too bad. I would be interested in this too. The used m56 valve cover could be an alternative for California cars, though.

My BMW Perf Intake passed smog np. Guess it depends on the smog guy. Besides, looks like you might be able to take this out every two years.

Only if you reinstall the original CCV components, which is a pain in the butt. Otherwise, you'll have a massive vacuum leak, amongst other things.

I thought the CCV stayed and this was a bypass.

Yes but the hoses going to the CCV would still have to be connected. You can't just leave them there disconnected because then you won't pass visual.

[johnrando]

Good point. But, I'm not sure it's THAT much of a visual. The ones I've seen are more a cursory glance to see that everything looks like it's in place. The CCV and hoses are so buried I don't think they really focus on that.

i'm pretty sure they will see the one that is disconnect at the very front of the engine and be like wtf lol

Not only that, but I don't think the car will run properly with it disconnected, so you'd have ​to go through the effort of reinstalling the factory one.
