Engine Valve Lash - Inspect/Adjust
SMCS - 1102-025
To prevent possible injury, do not use the starter to turn the flywheel. Hot engine components can cause burns. Allow additional time for the engine to cool before measuring valve clearance.
This engine uses high voltage to control the fuel injectors. Disconnect electronic fuel injector enable circuit connector to prevent personal injury. Do not come in contact with the fuel injector terminals while the engine is running. Note: Valve lash is measured between the rocker arm and the valve bridge. All measurements and adjustments must be made with the engine stopped and the valves fully closed.
Valve Lash Check
An adjustment is not necessary if the measurement of the valve lash is in the acceptable range. Check the valve lash while the engine is stopped. The range is specified in Table 2. Table 1 Quick Reference for Engine Valve Lash Setting Inlet Valves Exhaust Valves

Valve Lash Setting TC Compression Stroke of No. 1 Piston TC Compression Stroke of No. 11 Piston (1) Firing Order
0.38 ± 0.08 mm (0.015 ± 0.003 inch) 1-2-3-7-8-10 4-5-6-9-11-12
0.76 ± 0.08 mm (0.030 ± 0.003 inch) 1-2-5-6-9-10 3-4-7-8-11-12
360° from TC compression stroke Refer to Illustration 1 in order to locate the No. 1 cylinder.
If the measurement is not within this range adjustment is necessary. Refer to "Valve Lash Adjustment".
