My Ride: HellRot 330CI
Valve cover removed and white cream inside *Photos*

It all started when I noticed a white creamy substance on my oil cap a few months ago....First thing I did was get on e46fanatics.com and use the search feature to find answers...within a matter of seconds I have found a few threads about the white creamy gunk and learned what it was and how it might have gotten there.
For those who don't know its actually condensastion that builds up in the engine (aka water) when you use the car in cold weather and use it for short trips....It can come from different places...damaged oil cap seal...bad valve cover gasket...and many other places.
In my case if was a bad valve cover gasket....i had 80k miles so it was time to change it.
I was expecting the worse...I figured I would see oil gunk every were so before I opened the valve cover I poured a bottle of Gunk Remover and I let it run for about 10 minutes...I don't know if that bottle helped clean anything but my engine was very clean...no gunk whats so ever...except for the creamy oil under the valve cover...but everything else was VERY clean....thank you Royal Purple 5W-40!! thats all I used since the first day I got the car.

On with the pics......fyi...taken with a crappy phone camera...sorry
you can see the oil cap on the bottom right


even inside here....


Clean inside...

My Ride: needs a mechanic
From what I've read, that creamy gunk is from driving the car on short trips and not warming up to fully operating temperature...hence, the "moisture" not burning off. But, that's just what I've read.

yes you are correct...a bad valve cover gasket just makes things worse...and a bad seal on a oil cap as well.

water in the motor oil, not a good sign. You also might have a bad head gasket. Also check your water/coolant level, could be leaking into your motor.

It could just be moisture... im gonna do a vanos repair soon, and also do my valve cover gasket aswell. Its probably the same on mine since i had just the same as you shown on picture two.
I have a oil consumption so ive been told my ccv could be it.. so i changed that.. and that was full that yellow cream. They sad that yellow stuff also was symptoms of a broken ccv. And bmw said i didnt need to worry.

If you dont use any coolant i would be so afraid. But i recommend to change your ccv.. i havent seen any of that yellow cream since ive changed it.

Correct. My car developed a severe case of this oily cream from it being moved around the repair shop, like 50 feet and then turned off.

Nope, this is completely normal if you drive your car short distances or don't let it get to temperature for a long enough time.

I happens when you drive short distances. It's a lot more more common in the winter when it's colder outside. A good example is the cold glass of water on a hot day and it forms condensation on the outside. Same with your engine except it forms on the inside of places like your valve cover.


My car's creamy goodness which was much worse



The only cure is to let your car warm up fully and to not drive it like a pansy.

Mine used to be parked in my driveway for days. Now I'm beating the **** out of it every weekend. I did not know it could kill my engine. I hope it is not too late.

that plastic valve / camshaft cover never warms up like metal ones on short trips, keeps everything cool so moisture can collect on it.
