INSTALLATION
NOTE: Replace spark plug well seals and bolt
assemblies when installing a new cylinder head
cover gasket.
(1) Install new cylinder head cover gaskets and
spark plug well seals (Fig. 30).
(2) Replace cylinder head cover bolt assemblies.
CAUTION: Do not allow oil or solvents to contact
the timing belt as they can deteriorate the rubber
and cause tooth skipping.
(3) Apply MopartEngine RTV GEN II at the
camshaft cap corners and at the top edges of the 1/2
round seal (Fig. 31).
(4) Install cylinder head cover assembly to cylin-
der head. Install all bolts, ensuring the single (1)
stud used to attach the upper intake manifold sup-
port bracket is located in the #8 location as shown in
torque sequence diagram (Fig. 32). Tighten bolts in
sequence shown in (Fig. 32). Using a 3 step torque
method as follows:
(a) Tighten all bolts to 4.5 N´m (40 in. lbs.).
(b) Tighten all bolts to 9.0 N´m (80 in. lbs.).
(c) Tighten all bolts to 12 N´m (105 in. lbs.).
(5) Install ignition coil and spark plug wires.
Tighten fasteners to 12 N´m (105 in. lbs.).
(6) If the PCV valve was removed, apply Mopart
Thread Sealant with Teflon to threads and install
valve to cylinder head cover. Tighten PCV valve to 8
N´m (70 in. lbs.).
(7) Connect PCV and make-up air hoses to cylin-
der head cover.(8) Install upper intake manifold. (Refer to 9 -

block (Fig. 45).
(20) Using a mallet gently tap the bed plate loose
from the engine block dowel pins.
CAUTION: Do not pry up on one side of the bed
plate. Damage may occur to cylinder block to bed
plate alignment and thrust bearing.
(21) Bed plate should be removed evenly from the
cylinder block dowel pins to prevent damage to the
dowel pins and thrust bearing.
CAUTION: Use extreme care when handling crank-
shaft. Tone wheel damage can occur if crankshaft is
mis-handled.
(22) Lift out crankshaft from cylinder block. Do
not damage the main bearings or journals when
removing the crankshaft.

The crankshaft journals should be checked for
excessive wear, taper and scoring (Fig. 46). Limits of
taper or out of round on any crankshaft journals
should be held to 0.025 mm (0.001 in.). Journal
grinding should not exceed 0.305 mm (0.012 in.)
under the standard journal diameter. DO NOT grind
