Musashi TPM9176N Camshaft / Rocker Cover Gasket
Replacement Musashi camshaft / rocker cover gasket for Mazda MX-5 Mk2.5 / NB-FL 1.8 VVT 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 is used per engine. Age, repeated heat cycles and long-term compression can cause the existing gasket to harden, flatten or lose its ability to seal effectively.
Common reasons for replacement include oil weeping around the rocker-cover perimeter, oil residue around the top of the cylinder head, or replacement while the rocker cover is already removed for timing, valvetrain or other engine work.

Fitment advice: Suitable for the Mazda MX-5 Mk2.5 / NB-FL 1.8 VVT applications listed in the compatibility table. Earlier Mk2 1.8 non-VVT models and 1.6 models use different camshaft-cover gaskets. Turbo models are not included. Please note that the open-looking section of this gasket between cylinders 1 and 2 is part of the correct gasket design.
Other items to consider: When changing this part, you may also want to consider purchasing related camshaft seals, timing-belt service components, other upper-engine seals and service consumables accessible while the rocker cover is removed.
Useful tools / consumables: Normal hand tools, torque wrench, plastic gasket / surface cleaning tools and suitable brake cleaner or degreaser.
Difficulty guide: DIY Difficulty: Moderate. Access to the rocker cover is reasonably straightforward, but careful surface preparation, correct gasket positioning and correct cover refitting are important for a reliable seal.
Why Musashi? Musashi parts are aftermarket replacement components designed for reliable sealing, fitment and service use on the applications listed. They are a practical option for maintenance, repair and refurbishment work where the correct component style, size and application match are required.

Installation notes: Clean and inspect the rocker-cover and cylinder-head mating surfaces before installation. Remove contamination and old sealing residue without damaging the surfaces. Ensure the replacement gasket is correctly located and does not become pinched or displaced while the cover is installed, and follow the appropriate workshop procedure for cover tightening and any application-specific sealant requirements.
