Im on the same page as you, I'm not the god of motors or subbies for that matter, but I just don't see this issue occurring in a normal everyday driven car, ever. I spoke to the mechanic today, and he still has no help really to offer, Subby dealer said that itd b a waste of time to have car taken there...
I have found a possible motor (longblock) to replace mine tho. Heres the email from the guy. He is building a show car, and pulled the stock motor, and its been sitting since. Anyone able to look up the vin to see some kind of background on it?
The longblock is sitting on a pallet in my garage. It could be ready to ship by the end of the week if you want it. Plumbing, turbo, gasket sets, etc not included- but you can just bolt/unbolt most of the stuff from your old engine.
I have the VIN from the car it came from:
2005 SUBARU LEGACY GT LTD AWD VIN: 4S3BL676456205662
I would like to see it go to a good home, as it is a good mill.
