Where do you see a connecting rod in these two pics

My 1st thought was reversion on the one side the way the pistons are cleaned off. Oh and I cleaned out my inbox for PMs. I will look over the heads today.

3 and 5 should be at the same height,,looks to be different but then again,#1 may not be quit at top dead center.

any exhaust leaks on that side?that will help draw water back up.

Not that I am seeing, there was water spitting out between the riser and the riser extension that is a dry joint. I removed & pressure tested the manifold, extension, and riser as best that I could but found no leaks. I tore down the short block tonight but haven't looked it over yet. I will post some pics tomorrow.

Weird discoloration on the journals, looks like the rods were hammering on it

I am questioning whether this crank is some brand of Chinese junk & if it would be worth it to try to polish it or make another door stop & find a chevy crank. Tried to remove the harmonic balancer & stripped the threads on a brand new puller. And yes I removed the center bolt first in case anyone was wondering. Lol

randy,what is the part # on the rod bearings,from the pic they look to be a p bearing and thats no good if you have a crank with a bigger radius on the journals,it restricts the flow of oil from exiting the bearing and boils the oil.
