O-Ring — 18.5 × 2.4 mm (Cylinder Head Dowel)
This O-ring is used on the cylinder head alignment dowel to provide an oil-tight seal between the cylinder head and engine block. Installed around the dowel, it prevents oil seepage through the dowel bore while maintaining proper component alignment during assembly.
Heat cycling and engine oil exposure can cause the original O-ring to harden or lose elasticity over time, increasing the risk of leaks. Replacing this seal during head removal, gasket replacement, or engine rebuild work ensures proper sealing and factory-correct assembly.
Manufactured to precise factory specifications for size and oil resistance, this O-ring is intended for correct engine service and restoration.
