Could be coolant getting in the oil. Is the oil on the dipstick foamy as well or just under the cap?

I had this problem. Ended up replacing oil cooler seals and it fixed it. Also happened to replace AOS seals at the same time since I had the milkshake in my TB. If this is the case with you, you might want to consider that as well

Oil coolers are a popular fail point. Ive gone through 4.... Your car could still have the original seals. They updated the gasket because of this problem. Usually you will get oil in the coolant as well. So there could be another area at fault? Either way I would replace those seals and flush everything thoroughly. It can be done without removing any major components. For easier access, disconnect the exhaust and move it back as much as it will allow you to. I did that the first time I tackled it.

Could also be a bad head gasket job if it started right after that

Depending on the length of time the oil/coolant mix has been in the engine oil...week----month---6 months---a year?

If you have a high mileage car you should do the rod bearings. Normally changed at 120K to 150K is recommended (Sponsor 944Online and others)

From the WSM read bottom right paragraph:

Guys the car is an 86 with under 60K orig miles on the clock. The car has not run in 7 years! over the past two years, there has been a new head gasket (wide fire), new water pump and thermo, all new samco hoses. I was trying to take the car to the dyno today and figured I would change the oil before doing so. That is when I drained the chocolate milk.

for what it's worth, I overheated my car one day about 20 years ago (broken hose, needed to get to place to fix), and the heat damaged the oil cooler seals. The oil would leak into the coolant, but not the other way around. I drove it that way for about ten years until I gave the car to my brother. The only downside was ugly looking coolant (but no corrosion) and the softening of the hoses from the oil. Eventually, I changed the seals, ran TSP + water as coolant for a day, changed, repeated twice, and the car is fine.

If the engine hasn't reached full operating temperature for very long and has not been ran much over the last couple years, it could be condensation in the engine/ crankcase.

I've been living on 1 head gasket sealer treatment and then another bottle of Blue Devil a few months later (for good measure) going past 40 k miles with my 968 and no issues.... we're talking hard driving, endless transcons, etc (including another 1,200 mile trip just 5 days ago)--a year after this thing was eating a gallon of coolant every 5 minutes.

looks like i'm going to make it to the V8 swap without having to do the headgasket. I was told by one very respectable tech, that despite conventional wisdom, these engines respond quite favorably to the devils milk, and my engine is living proof. awesome, you ask me.

two months out from milkshake and still no word/update/s.

down but not out...

if it goes worse, you can always change to V8 and never look back.
