F22 w/NOS engine damage

Ok here's the deal... A friend of a friend hooked up his NOS on his 92 accord (i believe it's that year) with a 55 shot. He has no internals done on the F22 engine at all. When he was showing off all day constantly hitting the NOS eventually something happened to his engine. There seems to be no compression on at least 2 of the plugs when you pull them out of the engine and there is a small "clink" and "blub" sound now and the engine is running like shiznit. So my question is, what is most likely wrong; pistons, valves, something else? Just curious if anyone has a clue from my ungodly explaination. Thanks.

Ouch. 55 shot on a stock f22 huh? Hmmm... No compression of two cylinders... most likely piston rod(s) and/or rings, I should think. But it sounds like you've already entertained those ideas. So I'd have to say... all of the above? It might be time to take the engine in for some overhaul work. Just wondering, dry or a wet shot?

It was a wet shot, I believe it is a Zex(sp?) kit. As of yesterday after this all happened he is selling the kit :D

i'll tell you exactly what happened.....unfortunatly...it's more severe than you think....the exact same thing happened to me...

your crank shaft most likey lost compression and spun either one or two bearings. now there is no oil pressure because oil is just leaking through your bearings. if your crankshaft is intact and not scracthed... all you gotta do is get new bearings... if your crank shaft is scratched... dont drive it and do what i did.... go buy an h22.. lol.. N2O is some bad shit....

good luck man....
