Re: How to clean pistons?

You should get some seafoam and lpour some in each cylinder and let it sit overnight. It helps break up all build up in the ringlands.

Re: How to clean pistons?

just pick up a new set of pistons from EC automotive. a brand new set for me only cost $160 for my car, probably around the same for yours. and another $10 per piston to change the rods over. and theyll get you oversized pistons or whatever your engine needs along with new rings and such. then again, doing that is basically a rebuild anyways. seafoam FTMFW

That's pretty much how I do mine, just have to make sure it's a soft wire wheel and you don't gouge anything.
