Hmmm... now that looks like some perty bad piston slap thar son.
That should buff right out. I can't wait to see what the piston looks like. Suffice to say shavings of it have pretty much ruined the cam journals and probably everything else. More pics coming as I get things taken apart.

Wow. Either that bore was WAY outta spec, or you actually damaged the piston enough to cause that. There is no way you couldn't have heard that happening, unless it happened in fairly short order.
I want pics of that piston, and that rod bearing and journal. if it was rtocking that much, the rod bearing id going to come out concave and the journal hammered.

Yeah, detailed pics of everything are coming as I pull things out.
It happened over about 1k miles. It ran perfectly fine when warmed up, but I started to notice piston slap on cold starts, and it just kept getting louder every start. Also power output dropped off sharply.
Also, it was overheating badly towards the end. The headgasket was blown for sure on the Driver side rear corner, same location as dead cylinder. Probably warped the head with all the heat from combustion getting past the rings, or the extra friction from all the metal shavings everywhere.
Ironically, I still had 165 compression in that cylinder, and 180 in the rest.

Almost looks like the piston rings expanded too much for the available room in the cylinder..Piston slap usually will mark up the thrust faces on the cylinder wall..

That was my first thought after i read the word "overheating" and "blown headgasket" .. no fun. Makes me glad i'm at the wide end of JE's spec, i drove around with a blown HG, overheated almost every day, bores looked fine when the head came off.
Sorry bro. No Bueno.

thats a keeper...
u might beable to bore that 140 or 160 over but wow!

You can have it cheap, fast or good. Pick any two.
If you want it cheap and fast, it's not going to be good. If you want it cheap and good, it's not going to be fast. If you want it good and fast, it's not going to be cheap.

WTF....Now that got me all paranoid about my piston slap... I hope the pistons are salvageable. If not get some CPs. Let me know when you need a hand. No worries about the rally. I understand
However how come only number four is fucked? why not the rest, they slap just as much?.
Might be time for the FTY block, will save alot of time.

Goddam!
what the heck happened there Dan! that looks really nasty! It looks like the piston was rocking back and forth like mad! I remember when we put that back together the piston to wall clearances looked correct. If the head gasket was leaking into the cylinder real bad maybe it never let that piston heat up and expand correctly, just an assumption, i may be talking out of my ass. but that looks nasty!
