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

[slater]

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....

this is very cool - i hadn't seen these photos before. note how clean the secondary chamber is underneath the valve cover... my only concern is, does the condensate (mayo) collect inside the vacuum regulator assembly? and how serviceable is that assembly? looks like after a few removals the plastic cap would be pretty beat.

Any updates?

Oh man, this looks great!

I'm in for updates.

I've changed the title from in production to in prototype. Once they actually list for sale we can change back.

Its not designed to be serviceable. There were no pictures of the inside of that thing that I could find so I took a risk and carefully pried it off. BMW considers it a lifetime part and sells the entire valve cover as one unit. To my knowledge there are no replacement parts for that little round black cap or the diaphragm or spring.

I got this M56 valve cover used from a junk yard, and those pictures are exactly how it looked when I opened it up, no mayo. Before I installed it in my car I had it cleaned at the parts store for $17 and when it came back it looked BRAND NEW. I was surprised.

The M56 valve cover I got had a torn membrane. Was able to get the membrane from ebay (vanos-bmwcom)

Very cool! Now if only we could find someone who makes the black top cap and we would have all the "breakable" parts...

What about the one that comes on the ESS supercharger? The one on my car has a BMW emblem on it... looks very similar
