The engine failed at 91,000 miles. I bought the car with the engine knocking badly. Neither the crank nor 2-rods were salvagable. I can hardly believe how much used engines cost; I paid $1,200 for a new short-block from Subaru. With gaskets, oil pump, valve grind, etc., I'll have about $1,700 in it. The cheapest used engine I found had 95,000 miles on it and was priced at $1695 + freight! The old engine was full of sludge, especially the PCV system (it was totally plugged); I suspect the oil hadn't been changed in a very long time!
