Maintain precise engine alignment and reliable head gasket sealing with this Genuine Nissan Cylinder Head Dowel, designed specifically for Nissan Patrol GQ Y60 models fitted with TB42 carburettor and TB42E EFI engines. This OEM dowel is installed between the engine block and cylinder head to ensure accurate positioning during assembly and correct sealing of the head gasket.

Over time, cylinder head dowels can become corroded, damaged, or lost during engine rebuilds or head gasket replacement. A missing or worn dowel can lead to incorrect head alignment, causing coolant leaks, oil leaks, compression loss, overheating, and premature head gasket failure.

Manufactured to genuine Nissan specifications, this direct-fit replacement ensures proper alignment between the block and cylinder head, protecting engine integrity and long-term reliability.
