Help! Orange Engine Sludge!

This is the only place that I know of to get real help with any BMW related issue. Full disclosure -- this is for a 2002 530i. I had a 2000 323i that recently sold and got lots of help from these boards. Hopefully I won't get flamed for having a 5, but I figured I would be safe since its the same engine as the 6s in the 3's.

At any rate, I haven't changed the oil since I have had the car (few months) but I did have to add a total of almost a quart. It doesn't leak, so it must burn a little. I added Mobil 1 0-30 (i think, but will have to double check).

I didn't notice any the first time I added the oil about a month 6 weeks ago, but now there's orange gunk all over the top of the opening (!). Did i do damage by possibly mixing types of oil? What the heck is going on here??! What do I do? Can I still drive it to work?

I am going to go search the threads right now, but figured I would ask since its late Sunday afternoon, and I still have time to go get some supplies if I need to roll up my sleeves today.

Thanks all

It's common.

edit: eww, I'm thinking there's some coolant in your oil.

Nope - the color on the dipstick is fine. Also, forgot to mention -- it has about 65k on it, if that matters.

There's coolant in the oil??

Normal in our cold weather

This is a by product of short driving cycles and our subzero cold. I noticed you live in Minnesota. Take the car out on a long drive and it should burn off.

How long is your commute? The only worry is the oil separator which could freeze and burst. Search the thread for more information. There is an upgraded winter version which should help.

Probably just a symptom of short drives and very cold weather. Suggest you take a 30 minutes highway drive and keep it in third gear for a good ten minutes at over 4 thousand rpm to get the upper part of the motor really good and hot to burn it all off.

Tell me, why are you putting M1 0W30 in your engine?

If its only around the cap and only in the winter then its normal.

I had a VW for years that did this exact same thing.
