As some of you know, I was having a misfire in the #5 and #7 cylinder. Wasn't spark plugs, wires, coilpacks, or the injectors.

So this afternoon I decided to take the head off on the drivers side, really wasn't that bad, esp since I didn't have to do anything with timing like you would with a 4-cylinder. Ill let the pictures speak for themselves. This car ran awesome besides the misfire by the way, didn't really feel like it had a loss of power or anything. If you don't see it, the piston head is shattered on the edges on both cylinders that were having the misfire:








Which I guess explains these pieces I found in the plenium awhile back:



My questions
1) Does it appear that I have dropped a sleeve? I wasn't leaking coolant, which leads me to believe that I didn't drop one, but Im not sure. There was no coolant in the oil prior to taking the head off?
2) Where is the cheapest place to buy new pistons assuming the sleeve isn't dropped?

 

how did you manage this?

 

Previous owner did not take care of it at all, I got it in this condition.

 

im sending luca brasi to take care of them

 

Haha, somebody must be watching the godfather, I'll take some of his money, assuming the sleeves haven't slipped, its still going to be around 400-500 bucks to fix this.

 

watching part III now,,,

i am a godfather fanatic though

you gonna do the work yourself?

 

I do all the work myself, except for machining, just don't have the tools. Engines are so simple to work on.

 

oh i know it,, built the engine for my first rig at 15. my dear old 69 el camino,,,

if only guys like us had our own machining tools haha

 

That is gnarly. At 4:00 o'clock it looks like the block is damaged behind the sleeve. Is that dirt or a crack? Either way I think you need a new engine unless you know a good machinist.

 

It looks to me like you dropped a sleeve.
It's really hard to tell in a pic but it looks like there is a ridge at the top of the cylinder, I would crank it over by hand and run that cylinder to BDC and have a better look see.
