Well considering the contact points, it seems your pistons are hitting the head maybe? I'm not sure bc I'm no expert, but it seems logical. I don't know what would cause that though. Maybe that's your problem!

 

you have a problem

 

i have no freakin clue but i am suscribed...best of luck to you

 

it looks like something got in there and was getting smashed between the piston and the head.

 

def some kind of forign metal got into your engine and caused that. My old motor looked the same, but the damage was caused by chunk of the valve relief area of the pistons breaking off and getting whewed up in there.

the damage to the head was repairable and came out well

That definitely makes sense. I think this guys got it, the problem is, where did that come from? I'd try to find that information so the absense of that piece doesn't pose any more problems, as well as replace whatever it came off of...tough break though man, that looks horrible

 

blow by..........did u check you sparkplug tips to see if they broke?....did you find any metal in the cylinders when you took apart the engine?....it wasnt your valves because you would have contact points on them....time to upgrade pistons....good luck

 

Have you drained the oil? Any shavings? Doesn't make sense that something got into 2 cylinders, and only did damage on the front and back of piston. Cyl walls look fine too. almost like the pistons were banging up into the cylinder head? And you didn't find anything in the cylinders?

Are we getting the whole story here? Def sucks.

 

yeah why'd you take your head off in the first place? it looks like something that wasn't suppose to be but i honestly don't know..,.. goodluck with it all though

 

i had engine knock after running it too hard.

the 4th cylinder completely smached the spark plug shut. it probably did break the tip and thats what was being throwned around!

 

PM'ed

 

i just notice a small crack on the top and bottom of cylinder #4



will this give me problems?

 

Looks like Detonation

 

if there was metal floating around then why are the valves untouched?

 

Will a cracked sleeve give you problems???

yuh

 

ever noticed smokin issues?

 

no my car has never smoked =, not even during full boost

 

FULL BOOST FTL

 

looks like detonation to me

 

Possible rod bearing failure on cylinder 3 and 4. when the rod bearing goes it allows the piston travel further (possibly protruding the deck of the block) and could have made contact with the cylinder head. Especially if the head has been milled or the block had been decked at all which reduces said clearances.

 

well im not sure whats goin on with the car
but good luck trying to fix it

never thought about that, but it makes TOTAL sense.

 

could the type of headgasket play a role here....
