I have the head off the Honda for a valve job (pitted seats) and was wondering what you's guys use for carbon removal when the motor is installed in the car and just the head is off. The car only has 30,000 miles, but the exhaust valve lash was tight. Seafoam soaking on the piston tops? | ||

I've used carb cleaner for it before. It's pretty good about dissolving carbon. You probably want to make sure the pistons are at the top of the stroke so you can get everything, and it might remove some of the carbon ridge at the top of the bore, which I understand is probably good to have there. But it should work.  | ||

I've not had much luck with anything getting that stuff off two stroke pistons. About all I can do is scrape carefully. | ||

reep werent you ever single? Most guys scorch pans pull the piston and boil it in water. carbon will loosen and rub off easily | ||

Sweet! I'll do it on the grill (where I bake my cases to get bearings in and out). She never catches me there... Thanks for the tip! | ||

Well, being a car, I didn't need to pull the piston or cylinders to do it. I'd like to do it in car. | ||

It's fun to do it in car. That Honda's backseat lays out into the trunk... Oh, heck, my pan's scorched. | ||

Well, the family hauler is a Journey and the rear seats fold flat.Plus I have the Ram with a six foot bed that never has to be made. | ||

Just scrape it carefully. It comes off pretty easily, you just dont want to gouge the pistons. If you are uneasy about it, use a plastic scraper, then use compressed air to blow any debris out of the area between the piston and cylinder. | ||

Thats's exactly what the machine shop said today when I dropped off the cam seal. Thanks! | ||

"Just scrape it carefully. It comes off pretty easily, you just dont want to gouge the pistons.

I have done this in the past by folding a paper towel into quarters, and laying one on top of each piston, soaked with dish soap water. I left it overnight and all but the hardest parts wiped off. |
