Detention kills the pistons at the edge, and breaks away sections adjacent to the top ring. Link to comment Share on other sites More sharing options...

The log looks really good actually. The motor is getting rebuilt so no need for a camera. I'll post a pic or two when I get it apart. Link to comment Share on other sites More sharing options...

I know my turbo pistons have seen a lot more abuse and are still serviceable. Link to comment Share on other sites More sharing options...

I would have got it off today except I have all the kids home and only had a couple of hours to work on the car while the baby slept. Link to comment Share on other sites More sharing options...

No signs of detonation and one cracked piston. The pics tell the tale mostly but if it's hard to see then I can tell yas that it's cracked the ring lands, bent the rings and cracked through the piston about a quarter of the way around where the second ring goes. One thing that has me wondering is the broken piston is completely clean for some reason where the other 5 aren't. Could the oil have cleaned it off on the short drive home? It was burning a fair friggin bit from that cylinder. I did clean the piston crowns when I assembled it and it only ran for a few weeks so the carbon build up is very slight. More to the story, after a few weeks I replaced the plugs as it felt a bit sluggish on boost. It picked up a lot of power when I swapped the plugs and immediately after I swapped them, I went for a drive and it broke. 1 Link to comment Share on other sites More sharing options...
