This cylinder head gasket seals the combustion chamber between the engine block and the cylinder head. It sits at the interface of the crankcase and the head, containing compression pressure and preventing coolant and oil from mixing between passages. A failed gasket allows compression loss, coolant contamination, or external leakage, which reduces engine power and can cause overheating. Manufactured by Victor Reinz, this gasket is formed to the same thickness and crush profile as the original, so the cylinder head bolt torque sequence and final clamping load match the engine manufacturer's specification. On reinstallation, clean both sealing surfaces thoroughly and follow the prescribed torque pattern and angle-tightening steps for the head bolts.
