I have a couple of v6 engines here that have suffered head gasket failure. They have a lovely creamy coating throughout the innards but I am loathed to ditch them when they are the perfect base for rebuilding. I have used Forte biodegreaser on engines when I've dealt with oil cooler failure in the past but in that instance the engine(s) could be fired up to flush them through. These engines are on stands ready to be dismantled and cleaned up. My question is what you guys might suggest as a suitable cleaning agent on these engines as I take them to bits? Thanks in advance!
