Valve Clearance Check
- Open the engine compartment and fit paintwork protection sheets. Open to the service position.
- Carefully remove both engine covers, taking care not to damage the plastic fixings or the rubber inserts.
- Disconnect the battery ground cable.
- Remove the cam cover from the 'A' bank and the 'B' bank. Refer to VALVE COVER LH and VALVE COVER RH .
- Rotate the crankshaft so that there are four valves which are 'off the cam' (cam lobes uppermost), so that their clearance may be measured.
- Measure the gap on each of the four valves. Note which valve has been measured, along with its relevant clearance.
- Rotate the crankshaft a small amount so that the next four valves are 'off the cam'. Measure and note the clearances.
- Repeat this step a further six times, until all valve clearances have been measured and noted.
- Refit the cam covers and associated components. Refer to VALVE COVER LH and VALVE COVER RH .
- Refit the engine covers.
- Move the engine compartment cover from the service position and connect the gas struts.
- Remove the paint protection sheets and close the cover.
- Connect the battery and fit the battery cover.
