The Subaru is a 97' Legacy wagon with the 2.2L engine (129k). PO said that the engine had been run out of oil and pretty much melted. He said that he swapped in an engine with 90k on it. Vehicle runs perfect and I have put 8k on it since I bought it in November. Is there a way to find out what year the engine is and possibly what it came from? Not sure where to start looking. Thanks!
