Re: How bad do my pistons look?

Jason75,

I sure relate to how you say you feel sick about a situation that you've put a lot of effort into, and that looks bleak; I've been there and felt identical. I am not a mechanic, nor an engine specialist, but in LOOKING at the top end on your motor, to me, the pistons don't look horrible. One thing is for sure, and that is there was not a 3/8 nut bouncing around in cylinder 7 as there doesn't appear to be any high-velocity impact damage to the top of that piston. There is definitely a bit of carbon build up that could be cleaned up and vacuumed out of the holes. I'm sure the owners who have rebuilt lots of these blocks will weigh in with advice, but from the limited amount of diagnostics that can be determined from pictures only, I wouldn't think things are dire, that's for sure. One issue that did seem to stand out, is the water circulation holes sure seem full of flake and sludge and one would think that should be addressed before putting things back together. Chris.
