Anyone else have a J&E piston (95mm) rip apart?
Has J&E improved their pistons since this 96P model? I'm not going to use 96P again in any case.
Could have been worse. Broke two rockers, bent both valves. Maybe the head can be saved. Cracked the cylinder - that's a new one on me, though much better than my several previous engine blowups, where the rod with wrist pin attached broke the cylinder apart and then started in sawing slots in the case. Here it just cut grooves in the cylinder. At the moment I can't get the cylinder out, due I suppose to its having been hammered to a larger spigot OD, or the crack did that. Remains to be seen if the Pauter rod is still straight.
Happened on the chassis dyno last spring. Engine had only chassis dyno time from a year earlier. Took me a while to get around to taking the head off to see just what had caused the problem.
