1983 With WATER in oil
I have heard it could be the Oil Cooler. The car started and ran (16 months ago) with WHITE SMOKE form tail pipe.
That puts water in the cylinder since it is making Steam Vapor. This is where I get a little fuzzy on the 928.
The race cars have an oil cooler that is JUST FINNS no water contact. I assume since I have not had time to take it apart that the Oil Cooler is like the Trans Cooler with a jacket between the oil and Water.
I know
But if someone has experience with this I can eliminate buying head gaskets and pulling the motor if it is the Oil Cooler.
Not the Blue one that is GONE.

What does the coolant look like?
What does the oil look like?
Something to remember is that there is a fair amount of water produced in the combustion process (Hydro-carbons plus oxygen makes CO2 and H2O).
A car that's been sitting for a while may well produce a rather disturbing amount of steam until the exhaust warms up, especially if it's been started and run for short periods of time.
That moisture often ends up in the oil.
Not the "Chocolate Mousse" look of a bad head gasket, but there can be a fair amount of white goop around the oil fill cap.

I have resurrected 2 928s in recent years. One was sitting for 17 years and the other was 4 years. Both smoked badly for about 20 minutes but cleared up and ran fine.
check the oil, check the coolant.and go from there.

What does the coolant look like? Water,green Coolant last time I saw the car.

Thanks for the guidance
1. it IS USA spec
2. Car was parked for 27 months per my records then started and was a bug sprayer with white smok NO oil smoke or smell
3. Cars is in front shop with about 3 pounds of dust and dirt since it has been siting for 3 years.

yes the 78 79 9 2/8 did have oil coolers but the 1980 -1984 USA cars did not. Given the 55 mile-per-hour National speed limit and 85 mile an hour speedometers Porsche did not feel they needed oil coolers

That was the point of the story about my car, when the dealership ordered a replacement unit, only non-cooler units were available.

Sounds like your car doesn't have an oil cooler, but if it did a leaking cooler won't allow much coolant into the oil. The oiling system operates at much higher pressure than the coolant system and oil will get into the coolant, not the other way around.
Your symptoms sound like a bad head gasket, cracked head or cracked block allowing coolant into at least one of the cylinders. There it will burn and produce a sweet smelling white smoke when running. When sitting the coolant will leak past the rings into the sump and turn the oil into a milk shake. If this is the case the oil level will be high due to the coolant that has leaked into the sump.
Don't attempt to start the engine or even crank it. If a cylinder is full of coolant it could split the block and/or bend a rod.
