Valley gasket to fit the Rover V8. This is the later high quality OE tin/foam gasket that fits below the plenum chamber covering the camshaft and followers etc on the Rover V8 engine. This gasket requires 2 TVR E0154 seals to complete the assembly. This gasket can leak if there are issues with the breather system on the Rover V8 engine. This gasket is suitable for all the Rover V8 variants and is a better quality part than the earlier tin version.
