Thread: What do you engine guys see here?

Pat, that makes sense about the end gap causing the problem. The engine did get up to 230 a couple of times until the cooling system burped the air out, then it would come down and stay at 190-200. Maybe that didn't help.

Steve, it looked different to me last night when I first saw the scoring, but tonight when I took the pictures the true pattern of the scraping showed up and it was obvious they were very straight and deep, like steel had done it.

Rrumbler, yep, we have a new set of C heads that will get the full treatment. The ones we had are Ga heads and were done by someone else and will become doorstops.

Street T, we are going to start pulling things apart so we can disassemble the engine completely. We built the engine, twice actually. The first time was about 5 years ago and it sat so long before he got the car done that we tore it apart and completely went through it a second time.

On the plus side, we can salvage a lot of the parts to reuse when we get the new block back from the machine shop. The car had 50 psi oil pressure and the cam and lifters broke in very well, no wear at all on them. We will have the pistons cleaned up and at least 7 of them should be reusable, so we will maybe only have to buy one to replace that suspect one.

We will take EXTRA care this time fitting the rings and the rest of the parts to make sure this doesn't happen again. While we are talking about rings, what type do you guys like for a street engine.....cast iron, moly, chrome, etc.?

Thanks everyone for the help, I'll post some pictures of what the internals look like when we get it torn down.
