I'm suspecting my head gasket has failed due to the fan being disconnected and temp running high, water is like baileys and I seen gunk on the filler cap but not on the dipstick. Ive recently replaced the pressure switch to stop an oil leak so could this have let a little water in causing the gunk or should I be worried?
I want to take the rocker cover off to inspect and clean before I do an oil change and waste money but im worried that the current rubber gasket wont be usable for a quick inspection.
Any suggestions?
