I have installed a M56 valve cover with integral CCV in my e53. This seems to work really well. I am not using much oil, and don't have to worry about the CCV under the intake manifold... |

I'll get some in the next couple of days. I thought I already had some, but I can't find them.

yep , im back there again - i still have my set up though and ive become adept at taking off and installing the conventional CCV in our cars that i dont mind it at all now ...current consumption is "acceptable" to me but i would like it close to the negligible Bavarian moD result like i had...

BMW e39 oil consumption.
In all my years driving BMWs. This has been the most significant post I have adopted. My old e39 is currently being driven by my son. I believe 200K miles and very little oil use on this variant.

I'm about 500 miles from my 5000 mile oil change being due and I have only used 1 liter of oil. I've never had oil usage that low. Having the catch can allows me to recover oil that normally would have been burned, even with the PCV mod. Since the original mod doesn't call for a catch can I don't see how it really cuts down on oil consumption. I can say without a doubt putting a catch can in the system does. |

@ fifty150 -- you need to work on then baffling and/or the fitting that comes off the valve cover if you want to reduce the oil in the catch can. The original system had a cyclone oil separator which you disconnected when you did "the mod."

I get that. That was kind of my point. The original mod doesn't do that. It does exactly what I did minus the catch can which is why I don't understand how the mod could actually reduce the oil consumption without a catch can.

Have you had a California smog check with modifications like that showing yet? Any concerns or plans for when it is next needed?

If you have more flow because of blow-by and/or air leaking into the crankcase (eg. rear main seal) and you don't have the baffling to keep up, then you have more oil going with it and probably a check engine light. Like I said before, people don't realize how much luck there is involved in having this work. Most of this thread is a lot of BS.
