Revised Valve Stem Seals on
1985-87 Ford Merkur XR4Ti 2.3L Engines
The Ford Motor Company has released revised valve stem seals for
the 1985-87 Ford Merkur XR4Ti 2.3L engines.
According to Ford this engine may produce some blue smoke during
initial start. The smoke is caused by oil leaking into the
combustion chamber past the valve stem seals. The revised seals
carry Ford Part #E7ZZ-6571-B for the exhaust valve and
E7ZZ-6571-A for the intake valve.
Most gasket sets available through aftermarket suppliers should
include the revised seals. Engines manufactured after 7/15/86
are also equipped with the revised valve stem seals.
