Pics of the motor
I posted a few weeks ago about my buddys b20 vtec that blew up. Well he finally got the pics developed. There not great but here are a few.
 The center of the piston is gone but the cylinder walls where not very bad.  As I posted before, all 4 valve heads where gone. But the stems where still in place. Its kind of hard to see in the pic, but the entire combustion chamber in the head looked exactly like the top of the piston. Except for the hole. Any ideas on what happend?

all the fittings where fine, it ran with the stock bottom end for a long time. then he put high compression pistons(11.5 to 1 i think) in it. And it ran good and strong for a while after that.

Re: Pics of the motor
looks like a melt down, but why only on 1 cylender, maybe there was something in the cylender and it caused this all to happen. but i dont know

Re: Pics of the motor
if i had to guess, id say that the injector failed and it ran lean. the combustion temp would be a lot higher, and that could cause the valve stems to get hot and melt. this is just a guess though.

Re: Pics of the motor
detonation? weird that it ran well for a while and then that one cylinder gave out. Maybe when he last modded his engine he damaged it without knowing? How long was he running the engine?
