Valve mechanism Volvo B204

Blue smoke on acceleration after engine braking and rising oil consumption can point to worn valve stem seals or play in the valve guides – both are common check points when a B204 cylinder head is opened up. This category gathers the parts for the valve side of the B204 engine in the Volvo 940/960, so worn components can be replaced during a cylinder head rebuild.

The group includes valve guides and oil seals, valve spring washers, plus mounting hardware such as studs, nuts, sleeves and washers. Always check that the parts match the B204 specifically – the valve mechanism differs between Volvo's various four-cylinder engines, so a correct fit to the engine code is essential before ordering.
