My daughter has a 87 Porsche 944 with 202,000 miles on it. She lost her oil and spun #2 rod bearing, so I dropped it off at the machine shop and told him to do his thing while it was out. The cyl have no measureable wear, the pistons are fine, the rings show some wear. The head and valves look fine but going to do new rings, a valve job and a little port cleaning while off. I beleive this engine would have made 300 to 400 K if hadn't of lost an oil cooler.
