Subject:
Cylinder Head Gaskets
ATTENTION:
Service Manager/Service Technician
This bulletin supersedes Technical Bulletin Group 1, Number 9209, dated 8-11-92.
Models Affected:
All four cylinder engines from M. Y. 1983 and all eight cylinder engines from M. Y. 1978
Concern:
Marking cylinder heads which have been machined and using the correct cylinder head gasket after machining.
Repair Information:
Should cylinder heads require machining to the cylinder head gasket surface, the letter "N", approximately 6 mm in height, should be stamped on the
casting in the location as shown in Figure 1A and Figure 2A. If the final thickness dimension is at or between the specifications listed in Figure 1 and
Figure 2, a thicker cylinder head gasket is required. (See parts information.)
