1. Disconnect spark plug wires from spark plugs and valve cover. Disconnect necessary hoses and engine
wiring cover for removal of valve cover.
2. Remove valve cover bolts/nuts, seal washers, cable bracket, valve cover and gasket. Rotate crankshaft
clockwise (viewed from timing chain end of engine) until crankshaft pulley timing mark (groove) aligns
with "0" mark on timing chain cover and cylinder No. 1 is at TDC on compression stroke. Cylinder No. 1
is front cylinder at timing chain end of engine.
3. Ensure reference marks on camshaft sprockets are aligned and positioned in a straight line at top surface
on timing chain cover. See Fig. 7
. If reference marks are not as specified, rotate crankshaft clockwise one
full revolution (360 degrees) and realign crankshaft pulley timing mark (groove) with "0" mark on timing
chain cover and then recheck reference mark alignment.

4. With cylinder No. 1 at TDC on compression stroke, use feeler gauge to check valve clearance between
valve lifter and camshaft on specified valves. Perform STEP 1. See Fig. 8
. Record valve clearance.
5. To check remaining valves, rotate crankshaft clockwise one full revolution (360 degrees) and realign
crankshaft pulley timing mark (groove) with "0" mark on timing chain cover. Using feeler gauge,
measure valve clearance on specified valves. Perform STEP 2. See Fig. 8
. Record valve clearance.

7. If valve clearance requires adjustment, camshafts must be removed for access to valve lifters. Different
thickness valve lifters are used. Manufacturer recommends placing reference mark on timing chain and
camshaft sprockets, removing timing chain tensioner and then removing camshaft sprockets and
camshafts for access to valve lifter while supporting timing chain. To remove camshafts, see appropriate
article in ENGINES.
8. Remove valve lifter from cylinder head. Using micrometer, measure thickness of valve lifter. See Fig. 9
.
Using measured clearance and valve lifter thickness, determine correct thickness of valve lifter to be used.
See Fig. 12
and Fig. 13 . Install replacement valve lifter, camshafts and timing chain. Recheck valve
clearance.
9. Before installing valve cover and gasket, apply sealant at specified areas on cylinder head. See Fig. 10
.
Install gasket, valve cover, seal washers, bolts and nuts. Tighten valve cover bolts/nuts to specification in
sequence. See Fig. 11
