I noticed engine oil dripping from my AC compressor...what would cause that? Valve cover? My coolant is a little brownish too. And it is leaking from the coolant level sensor o-ring on reservoir tank.

Lots of places it could be coming from like valve cover gasket, upper oil pan gasket, cam seal, oil filter, oil spillage from adding a quart. What I first thought was the O-ring on the bottom of the dipstick tube. I've heard of a few leaking, including mine. Ya just need to get under there and look up. Follow the trail upward til it stops and there's your leak, the highest point.

Coolant contaminated with oil looks like chocolate milk. When was the last time the cooling system had service? Deanshark covered it so it is a matter of looking to find the leakage.

Mine looks like someone mixed the OEM red with green and turned it brown. The compressor is above the pan and filter..maybe the vc is leaking and mixing with the coolant leak from the reservoir..I found a hairline crack next to the coolant level sensor on the reservoir..

My coolant was almost black when I bought my car, I thought the head gasket was shot. Luckily........ it wasn't. I drained it, from the drains on the engine, put in 2 gallons straight (green) antifreeze, drove it for about 20 miles and drained it again. Perfectly green. I filled it normal with new AF and 6 months later it was still perfect. No need to flush for me. But....you should definately flush that ****out of there.
Now that I look more where the A/C compressor is, it's probably either the VC gasket or cam seal that's leaking.
