Valve Train Analysis— Engine Off—Valve Cover Removed
Check for damaged or severely worn parts and correct assembly. Make sure correct parts are used
with the static engine analysis as follows.
Valve Train Analysis— Engine Off, Rocker Arm
z Check for loose mounting bolts, studs and nuts.
z Check for plugged oil feed in the rocker arms (6564) or cylinder head.
Valve Train Analysis— Engine Off, Camshaft Roller Followers and Hydraulic Lash Adjusters,
Overhead Camshaft
zCheck for loose mounting bolts on camshaft carriers.
z Check for plugged oil feed in the camshaft roller followers, lash adjusters or cylinder heads.
Valve Train Analysis— Engine Off, Camshaft— Engines
z Check for broken or damaged parts.
Valve Train Analysis— Engine Off, Push Rods
z Check for bent push rods (6565) and restricted oil passage.
Valve Train Analysis— Valve Springs
z Check for broken or damaged parts.
Valve Train Analysis— Engine Off, Valve Spring Retainer and Valve Spring Retainer Keys
z Check for correct seating of the valve spring retainer key (6518) on the valve stem and in valve
spring retainer (6514).
z Check for correct seating on the valve stem.
Valve Train Analysis— Engine Off, Valves and Cylinder Head
z Check for plugged oil drain back holes.
z Check for worn or damaged valve tips.
z Check for missing or damaged guide- mounted valve stem seal.
z Check collapsed valve tappet gap.
z Check installed valve spring height.
z Check for missing or worn valve spring seats.
z Check for plugged oil metering orifice in cylinder head oil reservoir (if equipped).
Static checks (engine off) are to be made on the engine prior to the dynamic procedure. Klj . 14 ba

Valve Train Analysis—
Engine Running
z Start the engine and, while idling, check for correct operation of all parts. Check the following:
Valve Train Analysis— Engine Running, Valves and Cylinder Head
z Check for plugged oil drain back holes.
z Check for missing or damaged valve stem seals or guide mounted valve stem seals.
z Check for a plugged oil metering orifice in the cylinder head oil reservoir (4.6L engine only).
If insufficient oiling is suspected, check oil passages for blockage, then accelerate the engine to 1,200
rpm with the transmission in NEUTRAL and the engine at normal operating temperature. Oil should
spurt from the rocker arm oil holes such that valve tips and camshaft roller followers are well oiled.
With the valve covers (6582) off, some oil splash may overshoot camshaft roller followers.
Valve Train Analysis— Engine Running, Camshaft Lobe Lift— OHC Engines
Check the lift of each camshaft lobe in consecutive order and make a note of the readings. 1. Remove the valve covers.
2. Remove the spark plugs.
3. Install the Dial Indicator Gauge with Holding Fixture so the rounded tip of indicator is on top of the camshaft lobe and on the same plane as the valve tappet.
4. Rotate the crankshaft using a breaker bar and socket attached to the crankshaft pulley retainer bolt. Rotate the crankshaft until the base circle of the camshaft lobe is reached.
5. Zero the dial indicator. Continue to rotate the crankshaft until the (1) high- lift point of the
camshaft lobe is in the fully- raised position (highest indicator reading).
6. To check the accuracy of the original indicator reading, continue to rotate crankshaft until the (2) base circle is reached. The indicator reading should be zero. If zero reading is not obtained,
repeat Steps 1 through 6.
7. NOTE: If the lift on any lobe is below specified service limits, install a new camshaft, and new
camshaft roller followers.
Remove the Dial Indicator Gauge with Holding Fixture.
8. Install the spark plugs. Klj . 15 ba
