AntiRiceRacing

Long story short, i bought a hatch earlier in the year and its run like **** ever since. I bought it because it was clean and well set up plus a bitchin price. Recently i decided to tear it down and take the car in a different direction. I found out 3 of my pistons were chipped with missing pieces. There is build up on the valves (see below), how can i go about removing that before i sell the heads? Or should i not mess with it?

simple carb or brake cleaner, and a lite wire scrub brush will clean it right up

yeah, i just soaked valves off an old car i was working on in brake cleaner and it came right off with a small wire brush. looked good as new...

That worked on the intake valve, but the build up on the exhaust valve is like metal, it wont budge...

idk, try soaking a rag, and letting it sit on there for a bit?

I wouldn't sweat it to bad if you cant get them perfect.

Take them out of head and put on the wire wheel on bench grinder.

I would put the spark plug in and fill the chamber with gas. If the valves don't leak down, I would put them back on the motor and run sea foam. Or take a die grinder with a wire wheel and brake cleaner to clean them up.

If they do leak down, I would have the valves worked and let them clean the heads.
