How do my pistons look?

Looks like you're burning some oil on 2 of them while the top 2 seem almost too clean like they getting washed with coolant.

 

Really hard to judge. It would help if you could keep track of which cylinder is which. Maybe too, crank the engine (manually, using bolt on end of crankshaft, at right end) so that each pic is at bottom-dead-centre. And focussed.

What’s the miles on it? How recently acquired? How’s it running?

 

I would not be happy with that going on inside of any internal combustion engines that I own at the moment I can say that I mean if it was running correctly and not making a racket and all of that I might run it until I could be through with it but if it's one of my keeper vehicles I'll move over to another one and put this one in the bay and have a look at it when I have time that's why I have several generation twos so we're never under the gun and out of transportation that's when you make foolish decisions quickly and waste piles of money.
