CAUTION: The cylinder head gasket is to be
installed DRY. DO NOT use a gasket sealing com-
pound on the gasket.
INSTALLATION
(1) Remove the shop towels from the cylinder
bores. Coat the bores with clean engine oil.
(2) Install cylinder head alignment studs VM.1009.
(3) After determining the correct head gasket
thickness, clean the block and head mating surfaces,
place the engine cylinder head gasket over the align-
ment studs.
(4) Place the engine cylinder head over the align-
ment studs.
CAUTION: New cylinder head bolts must be used.
(5) Tighten the engine cylinder head bolts in
sequence according to the following procedure (Fig.
68) :
a. The threads and underside heads of the bolts
should be lubricated. Use the cylinder head align-
ment studs tool number VM-1009. Position the heads
on the block and secure with the twelve large center
bolts and spacers (clamps), finger tight only.
b. Ensure that the various clamps are installed
correctly and the head gasket remains in it’s proper
position, completely covered. Then, lubricate and
install the ten small bolts, also finger tight.
(6) Install the intake and exhaust manifolds with
a new gasket, partially tightening the nuts to a max-
imum of 5 N·m (44 in. lbs.). This will align the heads.
Refer to Group 11, Exhaust System and Turbo-
charger for the proper procedure.
(7) Then, tighten the 14mm bolts with special tool
VM.1019 in the following manner:
(8) 1st Phase: Tightening Head Bolts (Fig. 68).
Central bolts (A-L): Tighten all bolts, starting with
bolt I then J-K-L-A-B-C-D-E-F-G-H, to 30 N·m.
Tighten all bolts an additional 70°, starting with bolt
A and continuing in alphabetical order. Finally,
tighten all bolts an additional 70°, starting again
with bolt A and continuing in alphabetical order.
(9) Tighten the 12mm bolts in the following man-
