[QUOTE="96dreamer, post: 16190838, member: 52560"] Continued. Cylinder walls all looked great, very little glazing and hardly galling or scratches. [ATTACH=full]1570939[/ATTACH] So I kept tearing down. Didn't take long to find something though. Pulled the pan to find this. [ATTACH=full]1570940[/ATTACH] That is a large chunk of piston skirt from the forged Ross pistons that were in the car when I bought it. Immedietly pulled that piston/rod to inspect more. Rod bearings looked great so I had that going for me. [ATTACH=full]1570942[/ATTACH] Some how the piece was 95% intact in the pan, just a little bent up from smashing into the crank i'm assuming. [ATTACH=full]1570941[/ATTACH] [ATTACH=full]1570949[/ATTACH] [ATTACH=full]1570950[/ATTACH] Manley h beams were fine, crank was fine, all the bearing surfaces looked perfect and the cylinder of the piston that broke had a very minor scuff of aluminum that you a fingernail wouldn't even catch so I lucked out and all the expensive bits looked great. While tearing down and inspecting all the other pistons I found 7 of the 8 pistons had developed cracks in the same spot as the one that broke. So these had all been developing cracks and would have went eventually. So all things considered I got super lucky only one did in a situation where I was able to get it back home safe. [ATTACH=full]1570945[/ATTACH] [ATTACH=full]1570948[/ATTACH] Stopped when I had a bare block on the stand. [ATTACH=full]1570944[/ATTACH] After finding the culprit of the marble in a tin can noise I let everything sit for a while so I could make a game plan on what I was going to do next. [/QUOTE]
