Why did my engine explode? *Solved*

[Shifty]

As long as its West Systems epoxy it should hold up, kidding.

You never know, some people really have that much faith in JB weld.

duct tape should do it

couple years ago I was doing a midnight swap out and was taking my top end and putting it on a spare set of cases/crank. Pulled the cylinder only to find that both skirts on the pistons were cracked. I got lucky. Had 2+ seasons on that motor with a whole lot of time and competitions on it.

It happens.

I just saw this thread and I see you know where the pieces of metal came from.. but Im still going to say it.

Who put the rice on your one piston??

That sucks dude I hope your crank is still good.

Questions that need answering. What is a the thrust side? How long is too long on a set of pistons? Has anyone ever just replaced the circle spring on the rear seal? Why does your wife/girlfriend ignore you when you ask a question starting with "honey"?

Umm well there are alot of factors.
1. The engine has NEVER been rebuilt, its original from 1994
2. I put on a high compression head sunday, even though the rear cylinder was about 10 psi lower before
3. I ran a friends gas. Idk what the ratio was. He said it was 50:1. I guess my modified SJ needed a little more oil
4. Sunday was the first day it ran, for over a month, since it had sunk!


Im honestly not too sad about the fact it died. It was a strong engine for almost 20 years! The rear cylinder was dieing anyway, glad it happened yesterday instead of while on vacation somewhere.

for some reason i though this was on a fresh rebuild.
1. no way!? thats awesome, but way too long to be running.
2.sign #1 that needed a rebuild
3. never run someone elses gas. run your oil, your ratio, ect.
4. what!?!?!?!?!?!?:no:

Has anyone seen Wisecos do this ? I have only seen it in cast pistons.
