CYLINDER HEAD COVER(S)
DESCRIPTION
The cylinder head covers are made of stamped
steel. The covers are sealed with steel reinforced sil-
icon rubber gaskets. The cylinder head cover uses
rubber isolators at each fastener location (Fig. 21).
NOTE: Due to the tight packaging near the cylinder
head covers, which makes spill clean-up difficult, a
spill during an engine oil change may be misinter-
preted as an oil leak. When investigating an oil leak
in the location of the cylinder head covers and
intake manifold, follow the procedure found in Oil
Leak Diagnosis (Refer to 9 - ENGINE - DIAGNOSIS
AND TESTING) for determining the source of a leak.

EXHAUST MANIFOLD
DESCRIPTION
The exhaust manifolds are log type and made of
Hi-Sil-Moly (high temperature resistant) nodular cast
iron. The exhaust manifolds are attached directly to
the cylinder heads and a cross-over pipe connects the
two manifolds.
OPERATION
The exhaust manifolds collects the exhaust gases
exiting the combustion chambers. It then channels
the exhaust gases to the exhaust pipe that is
attached to the rear (right side) manifold.
