CLEANING
CLEANING AND INSPECTION
1. Before cleaning, check for leaks, damage and
cracks.
2. Clean cylinder head and oil passages.
3. Check cylinder head for flatness.
4. Inspect all surfaces with a straightedge (2) if there
is any reason to suspect leakage. If out-of-flatness
exceeds 0.019 mm (0.00075 in.) times the span
length in inches in any direction, either replace
head or lightly machine the head surface. As an
example, if a 12.0 inch span is 1.0 mm (0.004 in.)
out-of-flat, allowable is 12 x 0.019 mm (0.00075 in.)
equals 0.22 mm (0.009 in.). This amount of out-of-
flat is acceptable. *Maximum of 0.2 mm (0.008 in.)
for grinding is permitted.
CAUTION: This is a combined total dimension of
stock removal from cylinder head surface.
INSTALLATION - CYLINDER HEAD(S)
NOTE: This procedure covers either the left or
right cylinder head.
1. Clean all surfaces of engine block and cylinder
heads (Refer to 9 - ENGINE - STANDARD PRO-
CEDURE - ENGINE GASKET SURFACE PREPA-
RATION).
CAUTION: Remove all gasket material from cylin-
der head and block using a plastic scraper only.
DO NOT use a metal scraper, as damage to seal-
ing surface may occur.
NOTE: A multi-layer steel head gasket is used.
2. Install new gasket(s) on the engine block. Assure all coolant passages and bolt holes align properly..
CAUTION: Cylinder head bolts are coated, DO NOT
