Description

This is a Hard Exhaust Valve Seat for MG 1500 and 1600. Valve seat inserts are a very important component of the valve train in your MGA engine. These hardened valve seats are the interface between the Exhaust valve and the cylinder head and the Valve and valve seat work together to seal off the combustion chamber from the exhaust gases trying to escape. The valve seat also keeps the valve from having direct contact with the cylinder head and absorbs part of the combustion heat which is transferred to the valve by passing it on to the cylinder head. Originally the MGA engine was designed to run on lead fuel (gasoline) which cushioned the blow of the slamming shut of the exhaust valve. Now since unleaded fuel in your only options, hardened valve seats must be in stalled to stop the tulip wear of the valve face or the destruction of the cylinder head. During a valve grind you cylinder head should be inspected to insure the valve seal surface is in good shape to keep you MGA running great.
