Sludge

rickeyMember

My uncle stopped driving a few months ago and he wants to give me his 1999 Chevrolet Impala that has 150,000 miles. The car runs fine but when I took the Oil Cap off I noticed there was Sludge in the Valvetrain, it is black in color.

Is there any product out there that will clean this Sludge up, any recommendations would be appreciated.
