What are the signs of a blown head gasket on a 1994 Buick park avenue?
A blown head gasket may cause a number of different symptoms. Coolant in the engine oil, an engine misfire or oil leaking from the engine could all be a symptom. Each of these symptoms could also have other causes and an actual blown head gasket may show none of the above symptoms.It is easy to be mislead, when trying to diagnose a bad head gasket. Symptoms will often vary considerably, depending on how the gasket fails. The term "blown head gasket" does NOT necessarily describe a single thing. Head gaskets may fail in several different ways. With each failure type different symptoms may result. The symptoms each person sees depend on how and where the head gasket fails. To make diagnosis even more confusing, other things may cause the same symptoms as a head gasket failure. Another issue may be multiple failures which can cause more than one symptom. For example, a restricted radiator may cause an engine to overheat, very much the same as a head gasket failure. The farther we drive the vehicle, the more it may overheat. Often, intake gaskets cause coolant in the oil. Coolant in the oil is often mistaken as a head gasket. Each of these symptoms may suggest a head gasket problem, but may have another explanation. Diagnosing the problem requires experience and a logical approach.
