I've taken engines apart before, but quite honestly never took the time to "study" the parts to understand what they were telling me about engine operation. This is a small block 360 motor, weekend driver, about 7 seasons, a few 1/4 mile races in-between, but otherwise a normal 7k mile street time.

Well, I have taken quite the opposite approach this time around and would appreciate feedback on what these pics are telling you. As best as I can tell there are really only two problems here:

1) some main cap walk on #1 and #3, which shows in the cap<=>block spotting (there is probably a real professional term for this) and the tell-tale wear on the bearings

2) weird cylinder wall wear on #4, not sure if this may actually be a crack?
About 3 years ago I ran into head exhaust cross-over porosity which caused coolant to leak through to the cylinder, but it never locked - steam only as best as I could tell - and when I pulled everything apart the walls looked clean, and when the machine shop pressure tested the head to find the leak it was a tiny amount of air bubbles coming through, tiny enough that it took them a while to figure out where this was coming from

Beyond that I am a little surprised by the 2nd piston ring wear pattern, I expected it to look like the top one with even wear.

Here are the pics:

1) cylinder wear




2) connecting rod bearings




3) main bearings






4) piston ring


5) main cap walk

All feedback greatly appreciated, maybe this all looks "as expected", I am hoping those of you with way more experience than I can share your know-how.

Thanks!
