So im in the middle of a over haul on my 22re head. My valves are caked with some nasty stuff im looking for a safe way to clean them up. I know not to work on the seating surface. But what kind of abrasive would be safe to get the crap (mud) off. Also got a bit of build up on some of the piston heads. Is there a way to clean the tops with out removing or replacing them. The origional problem is leaking valves so im trying to not open the bottom end as the cylinder walls look fine. Just trying to get the gunk out safely.
Thanks
Bela
