Musashi Camshaft / Rocker Cover Gasket • TPM9175N

Musashi TPM9175N Camshaft / Rocker Cover Gasket

Replacement Musashi camshaft / rocker cover gasket for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC 1.8 and 2.0 petrol models listed in the compatibility table.

Designed as an aftermarket replacement for the original component, this gasket seals the joint between the camshaft / rocker cover and cylinder head, helping retain engine oil within the upper cylinder-head and valvetrain area.

One gasket set is used per engine. Age, repeated heat cycles and long-term compression can cause the existing gasket to harden, flatten or lose its seal.

Common reasons for replacement include oil weeping around the camshaft-cover joint, oil appearing around the upper cylinder head or replacement while the cover has been removed for other engine work.

Installation notes: Clean and inspect the camshaft-cover and cylinder-head mating surfaces before installation.
