This is horrible. I just read the thread and looked at the pictures. Sorry to hear.

Couple of questions though. Is the valve outline on the piston tops normal? I read in there that if they were hitting it would run like crap and you would notice that. I think that's obvious enough. However, if it's bumped up to it with really really minimal clearance, like .001 inch, then the output shaft takes a dump, engine revs wildly for a second, the intake valve top shears off as it made contact with the piston while the cam still turns and shoves a lifter up to the pushrod (that has bent and broken the tray already), lifter gets misaligned in the tray now and, well, did what it did.

I'm guessing the 3rd valve imprint is the cylinder the valve broke in?

If that piston can't travel the full range because it's blocked, I'm assuming that jams up the entire crankshaft and rods and the weakest point gives?

Dude this sucks to see. I'm just trying to think in order of events here. This is kind of what I do for a living. I can't see your cam having anything to do with this other than the chain of events that led up to it and that lifter got jammed in there. I don't see how a valve top can separate especially seeing that your valve springs are all intact unless contact was made with the piston.

Hope you are up and running soon!
