Piston damage

[Mile_high]

Just picked up a used LB7 today. The guy used a ball hone to clean up the cylinders to have a look. One bank looks fine. The other looks like the hone scuffed up the cylinders a tad. Two of them look like they have chips in the lip and a few dings down in the bowl. Are they ok or will this really hurt them?

I know nothing, but i think i would tear it down, hone the cylinder walls with a torque plate at a reputable shop and probably have them de lip and coat the pistons

Lets see what others say.

IMO it depends on what your guna do with the truck. And pictures can only have us see so much. It could look terrible, but not be anything to worry about at all from the pic.

If its going to be a work truck, remove pistons to make sure he didnt hone it with the pistons still in it :rofl:

If the cylinder have no scoring, simply run a ball hone through it, install new rings (if skirts / lands on pistons look fine) and run it!

It's going in my DD. I plan on building it so when my injectors get iffy I can swap out the engines. I'll take it apart this week and take it to a shop for inspection.

When you run a finger across those two they are really rough in a few spots, one of them is that way in the center of the piston.
