I`m in the same boat now. just bypass the the valve and install catch can or is there something I`m missing?

I will get in touch with G.A.S. to see whats going on with their Serviceable CCV kit beta test. I have not heard from them in a while. I see if I can put some heat under them to move on the project. When I spoke to Gary during the winter, he acknowledged that they were behind the eight-ball on the project. I will update this soon.

As far as a catch-can project, there is a multitude of information on other forums. Spend some time reading. If you want to give it a shot, don't go with a catch can that vents to atmosphere. With the M54, it been reported this can cause ring flutter. It must be closed system so that pressures/vacuums are balanced. If it wasn't for the German Auto Solutions kit possibly near completion, I would have implemented a catch-can already.

thx for the reply greendragon, I see some catch cans around that have 2 lines going to top of catch can and a clear hose along side of it so you can tell how much oil it is collecting. I was wondering if you need some type of small pcv attached to it. like the older chevs had on top of the valve covers?

GD, thanks for following up with G.A.S. I'm not having CCV trouble [replacement done before I bought mine], but am ready to go on this as a preventive measure, given the M54s' history on this issue.

Guys I wish Doru would chime in here.

He basically talked to Gary over the winter and knows why it is such an undertaking as far as ring flutter and such goes with vaccuum in the crankcase of the M54, which is why the G.A.S. solution to the CCV is taking much longer than most anticipated.

I hope he sees the thread because he explained it all to me over the winter and I don't have the old message.

I havnt had any real issues with the CCV (until this winter, i just cleaned the valves, still gotta find time to replace em).

Will your results from the addition of the ProVent differ from 'normal' engine applications?

if I use the above catch can method I shouldn`t get any piston ring flutter is that right?

Looks like a good setup, now I am debating getting a catch can, hose and a couple fittings from this company and having a serviceable setup as opposed to the cold weather kit on my workbench.

Oil Catch Cans

I don't think you'd have ring flutter, as basically the catch can is replacing the CCV and you aren't introducing more vaccuum in the crankcase since having the catch can is keeping it a closed design.

This catch can really looks amazing, and totally serviceable:

I had my ccv fail this winter so I have to do something about it before next winter, and I think the oil catch can would be fail proof.
those catch cans look awsome by the way, expensive compared to other catch cans out there.
