The intake gasket on my Lumina blew, I went ahead and tore the motor down to check the head gaskets and replace, the motor oil was a milky white, my question is when cleaning the parts such as the heads, can I just clean the heads in my solvent tank as well as the intake manifold, like the rest of the parts, or should they be taken to a head shop and be rebuilt? The car has 127,000 miles, I do not know the history of the car,however, it would start and run. Should I be concerned about the oil pump or anything else? I just purchased it to fix and sell. Also is there a oil flush that can be used to clean the block internally after I put it back togeather? Any help will be appreciated.
