one time thing or big trouble

[scubasteve]

my 1984 944 had an anti freeze leak for the first time- 2 cups - no oil to be found mixed in antifreeze- car sat for 2 days no drip of anti freeze -ran car on idle for 15 min - no antifreeze - cant find leak- system was pressure tested a good shop 3 times last month - now a little - very slow drip of oil - car had slow drip in past but now a little more . what does this once ex field car need?

It just needs some TLC, and to be driven.

They all leak oil, to one extent or another. try to pinpoint where the oil's leaking from. Then if it gets too bad, replace whatever gasket/seal is leaking.

Where does your car run with coolant? Two cups below the "Min" line? Or two cups below the "Max?"

Was the car completely burped? If it wasn't, that'd be one place coolant could go (as air came out).

If a shop pressure tested it and couldn't find a leak, and if it's not burping, it's probably coming out the overflow when it's hot. All cars have a different equilibrium point; if yours is happy at 2 cups low and doesn't go lower, I wouldn't worry about it.
