INSTALLATION
NOTE: Before replacing parts, inspect all related
valvetrain components for damage to prevent
engine misfire.
NOTE: Black valve seals are intake. Brown valve
seals are exhaust.
1. Install valve seals (1).
2. Coat the valve stems with clean engine oil and
insert them in the cylinder head.

4. Install valve springs and valve retainers (2).
5. Compress valve springs with a valve spring com-
pressor. Install retaining locks and release tool.
6.If valves and/or seats have been reground,
measure valve tip height (A). Make sure mea-
surements are taken from cylinder head surface
to the top of valve stem.If valve tip height is
greater than 52.96 mm (2.085 in.), grind the valve
tip until within specifications.
7.If valves and/or seats have been reground,
measure installed height of springs (B). Make
sure measurements are taken from top of
spring seat to the bottom surface of valve
spring retainer.If height is greater than 44.45 mm (1.75 in.), install a 0.794 mm (.031 in.) spacer in head
counter-bore under the valve spring seat to bring spring height back to 43.69 - 44.45 mm (1.72 - 1.75 in.).

LUBRICATION
DESCRIPTION
The engine lubrication system is a full-flow filtration pressure feed type.
OPERATION
Engine oil stored in the oil pan is taken in and discharged by an internal geartypeoilpump,whichisdrivenbythe
crankshaft. A pressure relief valve is located in the timing chain case cover; it regulates oil pressure. The oil is
pumped through an oil filter and feeds a main oil gallery. Also, oil is routedtoanexternaloilcooler.Themainoil
gallery feeds oil under pressure to the main bearings, connecting rod bearings, and camshaft bearings. Passages in
the cylinder block feed oil to the hydraulic lifters. The oil then flows through hollow pushrods, which feed the rocker
arm pivots.
DIAGNOSIS AND TESTING
CHECKING ENGINE OIL PRESSURE
1. Remove oil pressure sensor (Refer to 9 - ENGINE/LUBRICATION/OIL PRESSURE SENSOR - REMOVAL).
2. Install oil pressure gauge.
3. Warm engine at high idle until thermostat opens.
CAUTION: If oil pressure is 0 at idle, Do Not Run engine at 3000 RPM.
4. Oil pressure should be 68.9 kPa (10 psi) at idle or 310 - 517 kPa (45 - 75 psi)at 3000 RPM.
5. If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck
open.
ENGINE OIL LEAK
Begin with a thorough visual inspection of the engine, particularly at thearea of the suspected leak. If an oil leak
source is not readily identifiable, thefollowingstepsshouldbefollowed:
1. Do not clean or degrease the engine at this time because some solvents maycause rubber to swell, temporarily
stopping the leak.
2. Add an oil soluble dye (use as recommended by manufacturer). Start the engine and let idle for approximately 15
minutes. Check the oil dipstick to make sure the dye is thoroughly mixed as indicated with a bright yellow color
under a black light.
3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected area of oil leak. If
the oil leak is found and identified, repair per service manual instructions.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles), and repeat inspec-
tion.If the oil leak source is not positively identified at this time, proceed with the air leak detection test
method.
Air Leak Detection Test Method
1. Remove the PCV valve from the IAFM. Cap or plug the PCV valve grommet.
2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kPa (3 PSI) of test pressure.
3. Gradually apply air pressure from 6.89 - 17.23 kPa (1 - 2.5 psi) maximum while applying soapy water at the
suspected source. Adjust the regulator to the suitable test pressure thatprovide the best bubbles which will pin-
point the leak source. If the oil leak is detected and identified, repair per service manual procedures.
4. If the leakage occurs at the rear oil seal area, refer to the section, Inspection for Rear Seal Area Leak.
5. If no leaks are detected, turn off the air supply and remove the air hose and all plugs and caps. Install the PCV
valve.
6. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the vehicle at various speeds approx-
imately 24 km (15 miles). Inspect the engine for signs of an oil leak by usinga black light.

INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in therear seal area of the engine, a more
involved inspection is necessary. The following steps should be followedto help pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area:
1. Disconnect the battery.
2. Raise the vehicle.
3. Remove torque converter or clutch housing cover and inspect rear of block for evidence of oil. Use a black light
to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaftdamage.
b. Where leakage tends to run straight down, possible causes are a porous block, distributor seal, camshaft
bore cup plugs oil galley pipe plugs, oil filter runoff, and main bearing cap to cylinder block mating surfaces.
4. If no leaks are detected, pressurize the crankcase as outlined in the, Inspection (Engine oil Leaks in general)
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch forleakage. If a leak is detected between
the crankshaft and seal while slowly turning the crankshaft, it is possible the crankshaft seal surface is damaged.
The seal area on the crankshaft could have minor nicks or scratches that canbe polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially machined to complement the function of the rear oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until disassembled.
