So today i decided to remove the chain guides and paint my valve cover. when i opened up the valve cover there was heavy sludge and carbon build up in there. What are the most effective ways anybody here has gotten rid of this in their cars, besides removing it and taking it to get cleaned. ive used seafoam in a different car but i never opend up the engine to check it after. Any opinion is good thanks:bigthumbu
