New engine:
Tearing down the engine slowly...still can't find damn recommended crank grinder.
Now as I have time I took comfort to clean the valvetrain parts and lifters in a ultrasonic bath...
Rockers took some wear but I will lightly polish them, just enough to make contact surfaces smooooooth

Old engine:
Drove some 50 miles in new 5w40 Maxlife synthetic and oil pressure on idle is 20psi.
Now I only have to pass yearly inspection and it will have a winter sleep.

Okay, new engine apart.

I will measure skirts in next few days, only skirts show wear.
Cylinder bores have a bit wear marks from the cylinder skirts also, but honing is still clearly visible. No deep scratches, can't feel them with fingernail. But, you can feel the edge at the top of the cylinder bore with finger.

I plan to reuse the pistons, wear is there, but does not seem too much. See pictures, and tell me if it is a good idea to hone and re-ring. Thnx.

This is how ultrasound cleans the pistons and rods (scrapes are from manual wire brushing carbon deposits)....

Shall I try to slightly&gently polish the skirts? Something crossed my mind: Did anybody use that cerakote stuff on skirts?

Still need to measure the skirts, but now I am obstructed and out of the garage due to the word cup... I hope You cheer for us (Croatia )

Ceracote stuff is prolly not worth the money for a mild street engine but I don't know the costs, my factory pistons had over a 100k on them with little wear
Oh, GO CROATIA!
unless they are playing the US.

@General karthief got me wrong there, was just thinking into replacing worn 0.001" with ceracote. But You are right, looking into the price tag.... does not make sense....

Pictures of rubber polished pistons attached... proud about results!!!!
Roughly measure says middle of specification. I would say REUSABLE....

You reminded me with Your footnote:
Croatia played first official soccer game under modern independed flag with - USA. Way back in October, 1990. Google it :), I remember that match as it was yesterday.
