LS6 top end knock and map sensor code after over rev I had my C5 Z06 out at the drag strip for the first time after buying it from copart and getting it road legal. The car has about 105k miles. Everything was running fine driving it around town. But during the first pass I made down the strip, the clutch disc exploded as I was shifting from 1st to 2nd and caused the engine to over rev to maybe 7200 rpm. I immediately shut it off and towed it to a shop to have them put in a LS7 clutch. We immediately heard the engine knocking on the first start up after putting in the new clutch. It's also throwing a map sensor code and running very rough. I ending up towing it home so I could take off the heads and examine everything. We'll I took the heads off and everything looks fine, no bent push rods, the lifters look fine, valves all look good. I am now stumped as to what is happening but I am still a little suspicious of the lifters. I never found any vacuum leaks that might explain the map code either. Does anyone have any ideas?
