Good To Know

Q: Does this gasket need any sealant during installation? A: A head gasket of this type is normally installed dry on clean, flat surfaces. Always follow the torque sequence and specifications in your service manual for the 951 DI engine.

Q: Can I reuse this head gasket if I remove the head again? A: No, a head gasket is a single-use item and should be replaced any time the head is removed. Reusing one risks compression loss and coolant leaks.

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