3-6. ENGINE HEAD GASKET FAULTY
General Information:
Engine cylinder head gaskets seal cylinders and fluid passages. Leakage can be
detected through:
a.
lack of power,
b.
rough, uneven engine operation,
c.
abnormal pressure in crankcase or cooling system,
d.
contaminants in oil or cooling system, or
e.
engine might not start.
BDAR procedures are more difficult to perform on cylinder head gaskets, but limited
operation can be restored.
Frequent checks must be made for leakage and
temperature changes.
Engine rpm should be reduced.
