Description

Check part compatibility by using our vehicle filter options below. If you find your car, this part is compatible.

Precision-engineered for Ford Transit, Land Rover Defender, Peugeot Boxer and Citroën Relay engines, the Camshaft / Rocker Cover Gasket provides a reliable seal between the cylinder head and rocker (valve) cover to prevent oil leaks around the top of the engine. As engines age, the original gasket can harden, crack or compress, leading to oil seepage, visible leaks in the valve cover area, smoke on startup or low oil levels. This direct-fit replacement restores a proper oil-tight seal, helping maintain consistent engine lubrication and clean engine bays while avoiding damage to ignition coils and other nearby components.

Frequently Asked Questions (FAQs)

Q1: What is a camshaft/rocker cover gasket and what does it do?
A camshaft/rocker cover gasket sits between the valve cover (rocker cover) and the cylinder head, forming a tight seal that prevents engine oil from leaking out of the top of the engine.

Q2: Which vehicles is this gasket compatible with?
This gasket fits a range of diesel and petrol engines in Ford Transit, Land Rover Defender, Peugeot Boxer and Citroën Relay models where the OEM or equivalent gasket is specified — always confirm fitment with your exact engine code or part reference.

Q3: What are common signs this gasket needs replacing?
Signs include oil leaks around the top of the engine, oil on ignition coils/valve cover, burning oil smell on startup, visible drips under the vehicle, low oil levels between changes, or black smoke from burning oil on hot surfaces.

Q4: Should I replace the gasket if there are no visible leaks?
Yes — if your engine has rough idling, worsening fuel economy, or a smell of burning oil combined with high mileage, replacing an old, hardened gasket proactively helps prevent future leaks.

Q5: Is installation difficult?
Replacing a rocker cover gasket requires removing the valve/rocker cover and properly cleaning the sealing surfaces before installing the new gasket. It’s generally a moderate-difficulty DIY task, but professional installation ensures correct seating and avoid oil leaks.
