Is this normal looking?

I was getting ready to get some work done and seen this and got worried....

Is this normal? Should I not invest the money into piston/port work?

Piston

 

[traitor08]

If the compression is good the rings are fine. The piston is ok. Id do headwork since its off. Hell since its apart put a high comp piston in it and cam. How do the clinder walls look. Any crosshatch?

I work on computers for a living not engines so just getting this far made me happy lol. First time ever opening up an engine.

So I have no clue about crosshatch. I will go take another photo though.

hoprfully that image shows you what you need to see

 

[traitor08]

Your cylinder and consequently ring and piston should be fine. There is still crosshatch pattern in there. See the fine lines inside the look like real fine scratches. The make a lattice pattern on your cylinder walls. The helps with sealing the combustion chamber. Its when you see scratches or score marks going up and down the cylinder when you have problems.

Good deal going ahead as planned ty

Take your fingernail and see if there is a ridge on the side the head bolts to, also just rub around in cylinder and see if you feel any scratches. Just to double check. Just remember, we are looking at pictures and can't see everything.

Inside the cylinder feels smooth as hell.

The 4 head bolts however..... 1 of them seems to have about a 1 inch scratch on it. Almost feels like it rubbed when lifting the cylinder off. It is near the top of the bolt.

What kind of problem would that cause?

Thanks again for your help.

Also, breaking those nuts of the head bolts was a pain in the ass. I thought I was gonna snap it in half.

Something I remembered , I think it was Jody (Boost) was make sure that the cylinder stud does not loosen instead of the nut. The back right tends to do this as there is an oil gallery on this one.
