5. The valve seat must maintain an angle of 44.5 –
45.0 degrees angle.
6. Thevalvefacemustmaintainafaceangleof45.0
– 45.5 degrees angle.
REMOVAL
1. Remove the cylinder head (Refer to 9 - ENGINE/CYLINDER HEAD - REMOVAL).
2. Compress valve springs using Valve Spring Compressor Tool special tool# C-3422and adapter 8464.
3. Remove valve retaining locks, valve spring retainers, valve stem sealsand valve springs.
4. Before removing valves, remove any burrs from valve stem lock grooves toprevent damage to the valve guides.
Identify valves to ensure installation in original location.
INSTALLATION
1. Clean valves thoroughly. Discard burned, warped and cracked valves.
2. Remove carbon and varnish deposits from inside of valve guides with a reliable guide cleaner.
3. Measure valve stems for wear. If wear exceeds 0.051 mm (0.002 inch), replace the valve.
4. Coat valve stems with lubrication oil and insert them in cylinder head.
5. If valves or seats are reground, check valve stem height. If valve is too long, replace cylinder head.
6. Install new seals on all valve guides. Install valve springs and valve retainers.
7. Compress valve springs with Valve Spring Compressor Tool special tool #C- 3422and adapter 8464, install locks
and release tool. If valves and/or seats are ground, measure the installedheight of springs. Make sure the mea-
surement is taken from bottom of spring seat in cylinder head to the bottom surface of spring retainer.
8. Install cylinder head (Refer to 9 - ENGINE/CYLINDER HEAD - INSTALLATION).

10. Install spring compressor (1,3,), special tool#
9065, and exhaust adapter arm (1) tool # 9065if
needed.
NOTE: All valve springs and seals are removed in
the same manner.
11. Insert air hose (1) into spark plug hole and charge cylinder with air.
NOTE: Tap the top of the valve spring retainer to loosen the spring retainers locks.
12. Compress valve spring with valve spring compessor (3) tool # 9065and remove valve retainer locks.
13. Release spring compressor (3) and remove valve spring.
NOTE: The valve springs are interchangeable between intake and exhaust.
14. Remove valve seal.

1. Install valve seal.
2. Install valve spring.
3. Using special tool# 9065 (1,3,), compress valve
spring and install valve spring retainer and locks.
4. Release air charge in cylinder (1).
5. Remove spring compressor tool # 9065 (3).
CAUTION: Verify that the pushrods are fully seated into lifter and rocker arm. Recheck after rocker arm
shaft has been torqued to specification.

ENGINE BLOCK
CLEANING
Thoroughly clean the oil pan and engine block gasket surfaces.
Use compressed air to clean out:
The galley at the oil filter adaptor hole.
The front and rear oil galley holes.
The feed holes for the crankshaft main bearings.
Once the block has been completely cleaned, apply Loctite PST pipe sealantwith Teflon 592 to the threads of the
front and rear oil galley plugs. Tighten the 1/4 inch NPT plugs to 20 Nꞏm (177in. lbs.) torque. Tighten the 3/8 inch
NPT plugs to 27 Nꞏm (240 in. lbs.) torque.
INSPECTION
1. It is mandatory to use a dial bore gauge to mea-
sure each cylinder bore diameter. To correctly
select the proper size piston, a cylinder bore
gauge, capable of reading in 0.003 mm (.0001 in.)
INCREMENTS is required. If a bore gauge is not
available, do not use an inside micrometer.
2. Measure the inside diameter of the cylinder bore at
three levels below top of bore. Start perpendicular
(across or at 90 degrees) to the axis of the crank-
shaft and then take two additional reading.
3. Measure the cylinder bore diameter crosswise to
the cylinder block near the top of the bore. Repeat
the measurement near the middle of the bore, then
repeat the measurement near the bottom of the
bore.
4. Determine taper by subtracting the smaller diame-
ter from the larger diameter.
5. Rotate measuring device 90° and repeat steps
above.
6. Determine out-of-roundness by comparing the dif-
ference between each measurement.
7. If cylinder bore taper does not exceed 0.025 mm (0.001 inch) and out-of-roundness does not exceed 0.015 mm
(0.0006 inch), the cylinder bore can be honed. If the cylinder bore taper orout- of-round condition exceeds these
maximum limits, the cylinder block must be replaced. A slight amount of taper always exists in the cylinder bore
after the engine has been in use for a period of time.

18. Install a long bolt into front of camshaft to aid in
removal of the camshaft. Remove camshaft, being
careful not to damage cam bearings with the cam
lobes.
INSPECTION
1. The cam bearings are not serviceable. Do not attempt to replace cam bearings for any reason.
INSTALLATION
INSTALLATION - CAMSHAFT CORE HOLE PLUG
1. Clean core hole in block.
NOTE: Do not apply adhesive to the new core hole plug. A new plug will have adhesive pre-applied.
2. Install a new core hole plug at the rear of camshaft, using suitable flat faced tool. The plug must be fully seated
on the cylinder block shoulder.

CAUTION: 5.7L engines equipped with MDS uses both standard roller tappetsand deactivating roller tap-
pets, for use with the Multi Displacement System. The deactivating rollertappets must be used in cylinders
1,4,6,7. The deactivating tappets can be identified by the two holes in theside of the tappet body, for the
latching pins.
8. Install tappets (2) and retaining yoke assembly (1). (Refer to 9 - ENGINE/ENGINE BLOCK/HYDRAULIC LIFT-
ERS (CAM IN BLOCK) - INSTALLATION).
9. Install both left and right cylinder heads (4) (Refer
to 9 - ENGINE/CYLINDER HEAD - INSTALLA-
TION).
10. Install pushrods.

CRANKSHAFT
REMOVAL
1. Remove the vibration damper (1) (Refer to 9 -
ENGINE/ENGINE BLOCK/VIBRATION DAMPER -
REMOVAL).
2. Remove the rear oil seal retainer (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT REAR
OIL SEAL RETAINE - REMOVAL).
3. Remove the oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - REMOVAL).
4. Remove the oil pump pickup.
5. Remove the windage tray/oil pan gasket.

11. Remove main bearing caps (1) and bearings one
at a time.
12. Remove the thrust washers.
13. Remove the crankshaft out of the block.

INSTALLATION
1. Select the proper main bearings (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN
BEARINGS - STANDARD PROCEDURE).
2. Install main bearings in block and caps, and lubri-
cate bearings.
3. Position the crankshaft into the cylinder block.
4. Install the thrust washers (1).

6.Step 1 – 27 Nꞏm ( 20 ft. lbs.) torque.
7.
Step 2 – Turn main cap bolts an additional 90°.
8. Install the crossbolts with new washer/gasket.
Starting with crossbolt A torque each crossbolt to
28 Nꞏm ( 21 ft. lbs.)torque.
9. Repeat crossbolt torque procedure.
10. Measure crankshaft end play (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN
BEARINGS - STANDARD PROCEDURE).
11. Position the connecting rods onto the crankshaft and install the rod bearing caps (Refer to 9 - ENGINE/ENGINE
BLOCK/PISTON & CONNECTING ROD - INSTALLATION).
