my 2002 camaro ss blew the motor at 26k 3 weeks befor i blew the motor put in magic stick 3 and long tube headers and had a local guy tune it every one says it is the tune or a injector well any way hear are some pics tell me what you think there is a pic of my new 408 being put in and i just did drill mod with a ram power grip hd so i hope this holds up but and going to order the hp turbo kit but any ways please tell me what did this to my old motor thanks

 

Dam thats [pretty nasty i dunno what you did but why did you do the "drill" mod ive never seen or heard of it on a piston before?

 

i didnt do the drill mod om my piston i did it on my trans

 

i for got to say that the motor ran on this tune for 3 weeks befor the piston and cylinder cracked

 

looks like debris were in there.but no valves spark plugs miscellaneous bolts lost in the intake manifold.............im not too sure if detonation would gash in those patterns..who put in the camshaft....

 

unless detonation took a good chunk off the top of the piston and bounced it around...ms3 being a big cam...mabey the tune was too much for the fuel injectors.

 

looks like something gut sucked in there that shoudn't be there.

 

thats what I was thinking

 

have a plug break off?

 

thats the same thing i was thinking cause it def. looks like something was in there trashing the s##t out of things.

 

The size and shape of all those dents looks like the electrode from the #7 plug was bouncing around.
Are you sure it's the right plug? Take it out and report back the numbers.
Maby someone accidentally grabbed the wrong one and installed it.

What the hell is up with the RTV on the front cover?
GM spent tons of money on developing the bad *** gaskets we get to use.
Take it somewhere that deals specifically in LSx's to have it tuned next time.

 

i did put the cam in the spark plug is fine nothing got sucked in i think when part of the piston broke it did that damage and if you look the cylinder is craked in 2 places i think it was pre ignition from timing i dont know what else whould have cracked the cylinder

 

I dunno how much timing you had in the car, but to do that it must have been alot, or maybe you got some gas at a station that put 87 in a tank of 93, and then proceeded to hammer on the car hard on a really hot day... or you're fuel pump took a crap and things went really lean.


The way that piston has a hole melted in it looks like a nitrous detonation/hot spot type situation... were you spraying the car at all?

 

Looks like a little bit to much hotrodding to me... on a bad tune...

 

I think it was nuked by too little punctuation... I mean fuel... Punct-uel...

It was lean.

 

It is funny that more often than not it is #7. My friend just wiped out #7 he had 59cc AFR's, I think his CR was like 11.6-11.8. The outer edge of the piston came off at 10-11 oclock. Lean or detonation.

 

damn man you didnt hear that crap bouncing around in there? It looks like it took a little while before it punched through? I think something worked its way into your intake.....

 

if thats the case then he should check to see if theresa whole in his air filter or in the screen in the maf, if he still has the screen.lol

 

it looks exactly like mine. debris was stuck in my intake when I pulled it apart(not sure what it was). My plugs were also fine.

That does not look like its from detonation. Looks like something was in there

 

That is too bad about your motor. Good luck on your new one.
