Engine Damage: Part Out or Repair?

Give me a call i'll give a hand, it would be good to learn how to do this 1st hand before i rip my motor apart.

I'm pretty sure the problem is in the bottom end, and if so I'm just gonna fix it, and sell the car as planned :) The end.

It was the bottom end. Take a look at this picture taken when we pulled the head. The side of the piston looked melted and all 3 rings were gone in that spot.

ooh damn! ouch! Tough luck man. Time for something more tough!

Why not search around for a stock shortblock? I've seen them for sale for relatively cheap. ~400-600?

Off topic, but does a lot of detonation on a piston top ruin a piston? I have a block here that the hg was blown on and it had bad detonation. I dont think any of the numbers are really even visible on the top of the piston anymore. It still has good compression and the wall looks fine. I was going to sell it to someone for cheap before, but his unlce who is a mechanic said it isn't good anymore. His uncle is also supposedly a dsm guy and couldn't do a 6 bolt in a 2g swap either because they are too difficult. I wouldn't really believe him.

Check that, otherwise, if the piston tops don't have any holes, they just get peppered, no biggie.

How do I check that? Take it apart? It was when I had my many "good" head problems and it had over 150 for compression in that hole after the problem with one of the heads before putting a 6 bolt in. I never ran the motor after though. I just tested compression with different heads on it. The piston doesn't have any holes, but it was detonated a lot. (mainly salt now).
