Diesel Blown Head Gasket & Car Service Mechanic Slacks
Creek - Brisbane
When an engine is over heated from a cooling system failure or the diesel engine is put
under abnormal loading the increased temperatures of combustion will melt and burn
any sharp edge that protrudes into its path. Once the hot spot is established the extra
heat generated by the molten metal adds to the combustion temperature, increases
detonation and aggressively continues to burn away the cylinder head, sealing ring of
the head gasket, piston crown or edge of the cylinder wall. While this is happening the
performance of the engine will be noticeably reduced, accompanied by audible pinging
and knocking.
The coolant temperature will be high and the oil pressure considerably lower than
normal. A few good reasons to shut off the diesel engine but most drivers prefer to
squeeze the last few yards out of the engine. When the diesel engine is continually
driven after the head gasket has failed between cylinders, the combustion cross firing
between the two cylinders burns out a groove in the head and block face. The head will
often require building up in the burnt area before surface grinding.
