Diagnostic Solutions: Cylinder Head Repair
Cylinder head gasket failures are one of the most common mechanical issues facing today’s modern import technician. One reason head gasket failures are common is because the cylinder head gasket itself can become a wearing part. Since the aluminum cylinder head expands at a slightly higher rate than the cast-iron cylinder block, the cylinder head actually slides a few thousandths of an inch across the gasket surface as the engine warms up to operating temperature.
