Crank case vent valve replacement

[Piper1]

I remember seeing a write up on someone replacing their crank case vent valve due to the milky sludge that so many of us are seeing now. I for some reason can't find the thread on it in the search of how to in the problems, how tos, and discussion topics. If someone can help link me here it'd be great!

Also I was wondering once the crank case valve and hoses are replaced (did I see some where there was a kit of everything together that someone posted?) how do you get rid of the remainder of milky crap that's in there?
Thanks

You can buy the full kit from BMW which has the CCV and 4 pipes.

They are a bit fiddly to fit,but 3 hours should get it sorted..

If you wanted to really clean out the mayo,remove the cam cover and clean out from the inside. Replace the cam cover gasket and bolt "O" rings.

maybe this ?

Hey guys

I've been getting some mayo/yello sludge under my oil filler cap and in my disptick tube. This was because I've moved recently and doing shorter journeys in cold weather has led to build up of condensation which isnt going anywhere as I had a blocked breather valve. So, after research on here, e46 forums and Bavarian autos I attempted to change the oil breather/crankcase valve. My phone broke on the day I changed it and I had no digi cam to hand so no pics...sorry!

It took me around 3.5 hours with lots of bleeding knuckles! If you are going to do this yourself, a few tips: buy genuine BMW as parts are a perfect fit, buy all the hoses as they will break, watch the bav auto videos on YouTube fully before starting. Well worth the effort to do a DIY as labour savings are probably pretty significant.

the generalist, yup that was the post I remember. Thanks a bunch. Is there any chance of the mayo dissipating or is it pulling everything apart to make sure.

I got a fault yesterday for the oil level sensor so I'm trying to gauge how much time to give myself to do these all at once.

I wasn't sure if the ccv giving me the mayo might have caused the oil level sensor to go, figured it can't help anything so I want to do them at the same time.

I think they could be related, but water content would have to be quite severe to effect the sensor, so actually unlikely related. It is possible the sensor just needs to be flushed out if it were water content. The dilemma is the part is not cheap, and parts suppliers are often unwilling to refund electrical part returns, which precludes having a replacement on hand in case flushing does not work.

Considering the likelihood of successful remedial repair and what's involved, you are probably best off just replacing the stupid thing and be done with it.
