with shot #6 cylinder. First one had 58k miles, #6 had a hole in the piston. Likely caused by detonation due to low octane gas or the fact the owner had a manual boost controller. Second one at 70k miles, #6 had bad rings. This was determined by a leak down test, I have not yet disassembled the motor (probably will this weekend). If you can, do a leak down test and pinpoint the source of low compression.
