I am interested in buying a 1996 Oldsmobile Cutlass Ciera (3.1L V6) with 86,000 miles on it. The common problem of the intake manifold gaskets has already been repaired.
The day before I was supposed to test drive it, the owner emailed me and said that they started the car, let it warm up and they have a “major oil leak”. They said that they thought it might be the PCV valve, but they are having it towed to a repair shop to see what the issue is.
I emailed them back and asked if they know how many quarts of oil leaked out and how long it was running before they noticed the leak, as well as whether the “oil” light on the dash came on. They replied that It looks like about 1½ quarts, and that it had “no oil pressure”. They added that it is either the PCV valve or the oil pump has a leak around the seal.
I’m not terribly familiar with that engine, so while they are waiting to hear back from the mechanic, I wanted to see if I can get opinions on what happened and whether it damaged the engine. The owner seems to have limited mechanical knowledge, so there is a good chance that they are incorrect in their diagnosis.
