brake cleaner will remove that krap. ps, no chiseling! the rings have to seal against the sides of the ring grooves, and the fit and finish must be preserved. save the seal!
for what is the good life if not doing things thoughtfully?

spray or soak in brake cleaner, and a toofbrush work great! in the olden days we had carb cleaner that would make los pistones look brand new, but i'm afraid those days are gone. i got the latest, greatest carb cleaner, and it didn't work worth didly.

I scraped the carbon off the tops of mine with a broken piston ring and then threw the rod/piston combo in the dishwasher when the wife was at work. Came out lookin' like new! SHHHHHH!

Its got 250,000 miles, "some taper and a lip you can barely feel"...it's wore out brother. Save your time cleaning those pistons, toss them in the trash, buy some new ones and bore the block.

I'm thinking the same thing.

Combine or not, you are going to have to hone the step and the taper out for it to seal. How big will it be then?

Thousands of engines have been "rebuilt" like this and run just fine. Deglaze, new set of cheapo cast rings and go. No one's claiming it's as good as new but it'll be a definite improvement.

A easy way to see the taper is to put a used ring in the cylinder up at the top square it up, measure the gap, then push it to the bottom of the bore and remeasure. Im betting .008+ But should probably last 100K anyways, might start using oil pretty fast though
