After removing the cylinder head on my M42 to change the head gasket, it was apparent that there are 16 years of buildup on the tops of the pistons. There is flaky black carbon on the piston tops - maybe because the car wasn't properly tuned up on a regular basis.
Is there a simple way to wear this buildup down? What if I use a couple bottles something like Redline SI-2 in consecutive tanks of gas?
Any ideas?
I don't want to take the engine apart just to clean off the pistons, but would like to clean it up as much as possible while I've got the head off.
Thanks!
