Car had r2 with kiggly spring with retainer

 

Rod bolts loose and piston hit the spark plug tip ,be sure pull out the oil pan and check the rod bolts before install new spark plugs.

 

 

I've never seen a piston melted so entirely like that on a street car before...

 

Its not melted its metal on metal valve dropped too

 

My engine also look like that and my was a rod bolts broke and the piston hit the spark plug and destroy my engine I was running 30 psi e85 with new turbo kit ATP gtx3076r I has almost 40000 miles on the new set up before rod bolt give up

 

That makes the pics make more sense to me. Looking at it from my iphone it looked melted, LOL.

 

question is what broke first...

 

Wow, that is painful to look at!

 

Wow, was this the engine at 51psi and 125 shot nitrous?


Here is what I have seen happen, first who tuned it?

I have seen a cylinder get hot and detonate so bad that it burnt the ground strap off the plug, the metal bounced around in the cylinder before getting caught by the valve trying to close. This in turns breaks the valve causing it to drop into the cylinder. At this point the valve gets pounded to death between the head and piston ultimately putting a hole in the piston and destroying the engine.

I have also seen this happen when people install bigger cams w/o checking clearances after the fact before running the engine.

 

#2 doesnt look burned up so I'd presume the tune was okay and this was hardware failure of some kind. What rpm was it at when it failed?

 

Looks like some rolled up aluminum foil and threw it in there. Sorry for your loss

 

No ef3 engine

 

He was reving to 8250 on. 2.1L

Guy is ok with his loss but I just am shocked by this and wanted to be sure

 

Damn, sorry about your loss man.
