CLEANING
To ensure engine gasket sealing, proper surface preparation must be performed, especially with the use of alumi-
num engine components. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
INSPECTION
1. Inspect the cylinder head for out-of-flatness, using a straightedge and a feeler gauge. If tolerances exceed
0.0508 mm (0.002 in.) replace the cylinder head.
