We have a 1995 850 turbo wagon with 145K miles. I had what appeared to be oil in the coolant reservoir. Several days a go I had the cooling system mechanically flushed. Today, just three days later, I am again seeing signs of oil in the reservoir. The system was pressure tested with no sign of leaks or lost pressure. There is absolutely no indication of water in the oil system. This car has had all required maintenance since new.
Can anyone tell me a possible cause for the oil showing up in the cooling system? Is the turbo cooled by coolant and possibly a seal someplace in the turbo that could be failing? Any input is greatly appreciated. Thanks!
Rick
