im in the process of rebuilding my h22a, i took the head off today. figured id clean those pieces of aluminum that hold the cams in place. i was washing them in a tub with water, an all purpose cleaner mixed with amonia, i let them soak for 10 minutes came back and everything is now oxidized.

shorting of pulling out some 1200 grit sandpaper, how do i fix this?

 

pics???? do not sand the caps on the mating surface to the head or where the cam rides at.

 

use brake cleaner...its what you should of used in the first place

 

ill try it soon, thanks a lot. you should read my other post, the reason why i pulled the motor in the first place.
