Thanks OldTimer. The miles are pretty low, sub-100,00. Literally driven by a little old lady to the store and back. There are loads of issues to work through here. I skipped to the part about repairs b/c that’s the urgent part.
Oil doesn’t usually disappear all at once,
I totally agree. I’m getting information through a person it took 10 minutes to walk through verifying there was no oil on the dipstick. But here are the facts as I understand them.
My wife had it at the dealer 7 days earlier for a recalled airbag. They did a large courtesy inspection & ID’d problems. I have to assume they checked the oil. That may even be documentable. One problem identified was a leaking head gasket (ah, Subaru) that caused antifreeze to leak outside the engine, but definitely not into the oil. Could be relevant, maybe not. The car has been driven several days since then and the drain plug did not fall out. My wife/mother in law did not observe any leaking oil, no smoke out the tail pipe, and no pooling antifreeze. My wife says no idiot light went on until the “really bad” noise started and the check engine light came on simultaneously. A bit of information I am less confident in is my wife claims “they” (dealership?) were able put 5 quarts of oil into the engine after she had it towed in. Assuming we didn’t just violate the Law of Conservation of Mass, I’m at a loss to explain what happened to 5 quarts of oil in 1 week.
I agree, the bottom line is we need a new/used engine. And given the age of the car they have to be a dime a dozen, relatively speaking.
