Pulled the pistons and everything looks ok. No broken lands and rings look good also. Is it normal for piston skirt to have wear scuff marks? I found a little nasty black film on pan it sparkles so think its from lifters and cam they have abnormal wear like hardening was bad. Bearings ok I guess not really sure but looks like normal wear no copper. At this point should I check the main bearings also? This is the furthest Ive been in an engine so I have read alot but no experience makes it a little tough to know what is ok. Thanks

A little wear on the skirts are normal, however I agree some that some pics would definitely help judge...

Completely normal looking but I would not reuse them. New 5.3 pistons are cheap.

actually the one in the front has a spot where it has more damage almost like a small flat spot
Will do when the time comes but for now going 6.0l

That wear looks normal, does the cylinder wall itself have any scuffing?

No they look good except for #8 has a vertical scratch barely can get my nail to catch.

If you can feel the scratch with your fingernail, usually the rule of thumb means that it would at least need a hone.
