Jeep J-10 Series 1982 Technical & Service Manual page 151

NOTE: The 360 CID engine uses an aluminum coated
laminated steel and asbestos gasket. Retightening head
bolts after engine has been operated is not necessary.
(1) Apply even coat of nonhardening sealing com
pound to both sides of replacement head gasket.
NOTE: Do not apply sealing compound to head and
block surfaces. Do not allow sealer to enter cylinder
bores.
(2) Position gasket flush on block with stamped
word TOP facing upward.
(3) Install cylinder head over gasket.
(4) Tighten cylinder head capscrews evenly with 80
foot-pounds (108 N»m) torque following sequence out
lined in figure 1B-123. Then repeat sequence and tighten
screws with 110 foot-pounds (149 N»m) torque.

Rg. 1B-123 Cylinder Head Tightening Sequence
(5) Left side: connect air pump mount bracket and
power steering pump, if removed, to cylinder head.
(6) Right side:
(a) Connect alternator support bracket to cylin
der head.
(b) Install air conditioner compressor mounting
bracket, if removed, and battery negative cable on cylin
der head.
(7) Adjust all drive belts to specified tension. Refer
to Chapter 1C—Cooling Systems.
(8) Install exhaust manifold and tighten retaining
screws with 25 foot-pounds (34 N»m) torque.
(9) Install intake manifold. Tighten retaining
screws with 43 foot-pounds (58 N«m) torque.
(10) Install all disconnected pipes, hoses, linkage and
wires.
(11) Install push rods, rocker arms and bridge and
pivot assemblies in original position. Loosely install cap-
screws through bridges. Tighten capscrews alternately,
one turn at a time, to avoid damaging bridges. Tighten
capscrews with 19 foot-pounds (26 N*m) torque.
(12) Reseal and install cylinder head cover. Tighten
retaining screws with 50 inch-pounds (6 N«m) torque.
(13) Install spark plugs and connect ignition wires.
(14) Fill cooling system to specified level.
ENGINES 1B-83
LUBRICATION SYSTEM
Oil is pumped from the sump of the oil pan through a
pick-up tube and screen assembly to a horizontal oil
gallery located at the lower right side of the engine block
(fig. 1B-124). A passage in the timing case cover chan
nels oil into the oil pump. Pressure is developed when oil
is driven between the gears and pump body.
The oil is forced from the pump through a passage in
the oil pump cover to the oil filter (fig. 1B-125).
The oil passes through the filtering element and on to
an outlet passage in the oil pump cover. From the oil
pump cover passage, the oil enters an adjoining passage
in the timing case cover and is channeled into a gallery
that extends up the left front of the cylinder block. This
gallery channels oil directly to the right main oil gallery,
which intersects with a short passage that channels oil
to the left main oil gallery.
The left and right main oil galleries extend the length
of the cylinder block. The left oil gallery channels oil to
each hydraulic tappet on the left bank. The right oil
gallery channels oil to each hydraulic tappet on the right
bank. In addition, passages extend down from the right
oil gallery to the five camshaft bearings and on to the
five upper main bearing inserts. The crankshaft is
drilled to allow oil to flow from each main journal to
adjacent connecting rod journals. A squirt hole in each
connecting rod bearing cap distributes oil to the cylinder
walls, pistons and piston pins as the crankshaft rotates.
A small passage within the front camshaft bearing
journal channels oil through the camshaft sprocket to
the timing case cover area where the case and sprockets
throw off oil to lubricate the distributor drive gear and
fuel pump eccentric (see insert, fig. 1B-124). The oil
returns to the oil pan by passing under the front main
bearing cap.
Oil for the rocker arm assemblies is metered through
the hydraulic valve tappets and routed through hollow
push rods to a hole in the corresponding rocker arm.
This oil lubricates the valve train, then returns to the oil
pan through channels at both ends of the cylinder head.
Oil Filter
A full flow oil filter mounted on the oil pump at the
lower right-hand side of the engine is accessible from
below the chassis.
A bypass valve in the filter mounting base provides a
safety factor in the event the filter should become inop
erative as a result of restriction from sludge or foreign
material accumulation (fig. 1B-126). Oil Filter Remover
Tool J-22700 will facilitate removal.
Before installation, apply a thin film of oil to the filter
gasket. Do not use grease. Rotate filter until the gasket
contacts the seat of the filter base. Tighten by hand
only, following instructions on replacement filter. If in
structions are not printed on filter, tighten filter until
gasket contacts seat and then tighten an additional 3/4
turn. Operate engine at fast idle and inspect for leaks.
