This doesn't look right...

 

Pistons are in good shape

 

I've seen a thread with a similar pic here before. IIRC that hole is normal, but I'll let someone else chime in on wtf that is for.

HOLY detonation batman, how much timing advance were you running? PSI?

 

Yes nice healthy piston

 

15 PSI on a GT2554R. Timing was 10° too far advanced. It was fun.

Anyone got word on that hole tho? I'm curious if this block is junk

 

thats the oil return. it would be a problem if it wasnt there..

 

block hole is normal, pistons....not so much

 

normal. i tried to find a pic of mine, but can't.
i have the same hole.

 

i dont really see much det in the pics, just really hot melted pistons

 

hole is normal. are you selling the pistons? collector's item

 

how were the cylinder walls?

 

For the right price lol I planned on keeping them to show my kids how badass my flamboyant car was.

Surprisingly good I think. Little aluminum buildup from the melted piston. I don't know what I should all get done at the machine shop to get this thing back together.

 

Yeah, that looks norma... ...HOLY CRAP!

 

Don't mind the cobwebs....

 

I think you might be thinking of my thread asking the same question about that hole.

 

It just doesn't look factory...

 

It's a very raw hole in the casting, but as hidden as it is they obviously didn't give a ---- how they look. Everyone's looks a little different.

 

There absolutely has to be a hole there. That is how oil gets to the bearings. The crank does not ride on the bearing itself, but rather the oil film in between itself and the main bearing. If there was no oil there, it would take all of 3 minutes to completely eat the bearings. You gotta read up on engines man.

 

I'm pretty sure that we're all talking about thr large, rectangular, roughly-cast hole in the block next to the cylinder bore, not the drilled oil galley in the main bearing journal.

Fail on my part. What I get for posting when my eyes are dialated and can't see things.
