SETTING THE VALVE LASH
To properly set valve lash on the OVRM engine make
sure the engine is cold and at TOP DEAD CENTRE on
the compression stroke (both valves are closed). The lash
on both valves is 0.05-0.15 mm (.004") between the rocker
arm and the valve stem. (Fig 71).
To lock this setting hold the Allen wrench on the pivot ball
screw and tighten the lock nut to 65-85 inch pounds
(6.5-8.5 Nm) of torque. Double check the setting to make
sure that it did not change when the lock nut was
tightened. (Fig 72).
Place a new rocker arm cover gasket in place and install
the cover back onto the engine. (Fig 73). Torque the four
screws to 30-50 inch pound (3-5 Nm).
