Went to change oil and I saw this
- Thread starter Aimster

I noticed some smoke coming from my engine.
I thought it was because of some oil that was leaking on the bottom... The top of the engine cover looked like it was wet too but I didn't touch it, was too hot.
I've been driving this thing around for awhile. Mainly to work. 10 miles there and back.
Will I be okay driving it to the dealership that is 30 miles away or should I get it towed?

Drain the oil and check for water by using a hotplate. When if gets HOT, place a drop of oil on it, if if crackles, there is water.

Otherwise, it could be simple condensation or a bad PCV system.

I would check your antifreeze and see if you have oil in there. If so, my guess is a cracked head. If not, then it is probably just condensation, which is normal and not bad.
X5 forum is saying oil separator.
I see what leaks under my car. I park in the garage.
It's the windshield wiper fluid and oil. Two different cases.
I had a coolant leak before. I fixed that. The disappearing coolant is not leaking. It's going somewhere else. Maybe that's why my oil is fraked?

I've never seen oil in the coolant, doesn't mean it cant happen, just means I've never seen or heard of it.
Disappearing coolant and oil that looks like mustard are two sign's of a blown head gasket, though both could be caused by other problems and be unrelated. I'll stick with my first guess for now, you need a head gasket.

If its disappearing you have a leak, it just may be inside the engine. That would be significantly worse than it just dumping coolant all over the ground.

Drain the oil, what does it look like?
if the oil is normal when you drain it then that is just oil/water mix from condensation built up from your short trips in the winter. That happens sometimes, a lot of cars do that in the winter when you don't take long enough trips to burn off the condensation inside there.
Check your oil when you drain it, that will tell you if it is actually a problem or not.

Is it possible for the reverse to happen? Recently I kept getting low coolant signals... added some coolant to the coolant tank, signal came on again, added some more... signal came on AGAIN. Finally popped the radiator cap and saw gunk that looks identical to the stuff in the pictures in the original post.
Bad oil separator will give you wisps of white smoke in your engine when you start your car, but it will go away almost immediately -- speaking from experience with the same engine as you: m62 V8 in my 540i. Not a hard fix, but time consuming. I don't think that's what you've got though. I don't see how coolant would be getting back into your oil from a bad separator... especially with enough volume to give you a milkshake like that. You most likely have a bad head gasket or a cracked head -- BMW aluminum blocks are notorious for this. If you've run hot even once, you have a high chance of having a cracked head.

In engines with high compression or that otherwise tend to experience high positive crankcase pressures (e.g. turbocharging), the PCV system often incorporates an air/oil separator. This allows oil that gets pulled into the PCV system to drain back into the sump while reducing the oil sucked into the intake charge by the PCV system.
If the PCV system starts to get clogged up, water and other contaminants can get trapped in the separator and cause issues. The separators rarely "go bad", rather they simply need to be cleaned.
