ERC7865 is a valve stem seal for the 3.5 V8 twin carburettor engine, designed to control oil flow past the valve stems in the cylinder head. These seals prevent engine oil from bei ng drawn into the combustion chamber past the inlet valve stems, a common cause of blue exhaust smoke, elevated oil consumption, and fouled spark plugs on ageing V8 units. Replacing worn stem seals restores correct oil control without requiring a full engine rebuild.
