This weekend I disassembled (engine out of car) a 2001 2.0 engine to look for the lack or compression in #2 cylinder. I found a small chunk of metal (less than 1/8 inch square) missing from one of the exhaust valves. I would normally say great I only need to have the cylinder head fixed and not consider further action. However, the inside of the block in the area of the crankshaft looks like burnt toast. There was some granular material on the oil pickup screen but not enough to consider any starvation of oil. However, I believe the oil pan has previously been off as when I got to the last two pan bolts the pan came free of the block with no need to fetch my rubber hammer. I have a question in about this to the previous owner but no answer so far. I did find a small amount of granular material in the return oil hose from the turbo but not enough to block the flow. My question is what is the best way to assess the condition of the rod and main bearings and the crank. Also, should I be concerned about carbon buildup around the rings given the coating of burnt toast like stuff on the inside of the block. What is the best method to assess the bearings. Is plastiguage something to consider or is end-play the best method? I bought the car not running so I don't have any idea of how the engine ran at this point. I did a compression test before disassembly and got normal compression readings on all but #2 where I got zero. The odometer reads 123,000 miles. Another question, should I rebuild the turbo while I have everything apart. Also, is this the right time to put in a timing chain? The sprockets still look good. Please let me know if you have advice on best next steps. Parting thought, the clutch was down to the rivets if this stimulates any thoughts. Is this about right to wear out a clutch?
