Good To Know

Q: What are the signs of a failing head gasket? A: Common symptoms include coolant loss, white exhaust smoke, overheating, and low compression. A leak-down or compression test can confirm the diagnosis before teardown.

Q: Should head bolts be replaced at the same time? A: Many service manuals recommend new head bolts on the 951 engine since they can stretch. Always follow the specified torque sequence and values during reassembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
