Good to hear, I never have mayo in the summer, but come winter time it's terrible. I'm tired of replacing ccv's every 2 years...

do the e46 3.0i cars like 330i or 330xi have a pcv or ccv system?

i saw its for some other 3.0i models... would it work for ours?
i just stumbled on it and was curious

Anything with an m54, should be all the same

would that kit be a new ccv or is that bypassing the ccv with a pcv?

It is bypassing the factory CCV system and using a traditional PCV in place. And yes this will work on any car with a M54, M52TU, I've done this on numerous E46's already. My X5 is still on the original PCV valve that's been going strong for over a year now, still no oil consumption or any negative side effects.

^Thats phenomenal and thanks for the constant updates - in a few years if I need to attend to this CCV system I would most likely definitely be doing this mod.

Ok, I did this yesterday, it wasn't terrible, and like a few other people mentioned you have some more vacuum, you notice it trying to take the oil fill cap off after you shut the engine off, but no lights and I'm looking forward to being mayo free!

Yes there will definitely be a vacuum increase after the mod, but so far my engine has been working great with it, keep us posted!

You mentioned in an earlier post that you were working on finding/researching a PCV valve with a smaller orifice that would give a lower vacuum signal. Did you have any luck or have you staid with the original PCV part number you showed in a earlier photo?

I ended up staying with the original valve. The engine is running flawlessly and I haven't experienced one hiccup with this design, so I figured I would keep it running like this to see if there would possibly be any downsides in the long run. This engine seems to be loving the extra vacuum.

One nice little side effect from that is that last year my rear main seal had some very very slight seeping, after this mod and the extra vacuum everything has been bone dry between the engine and transmission. seems like its keeping oil leaks at bay.
