PROBLEM:

NOISE FROM TOP END OF ENGINE - TAPPETS The customer complains that when the engine is idling following a cold start, a persistent tapping noise can be heard from the engine compartment.

CAUSE:

The ‘O’ ring seal on the oil suction pipe may have been damaged during engine assembly. This will allow air into the engine oil and will subsequently lead to noisy tappets.

ACTION:

To confirm a customer complaint of the above, allow the engine to idle from cold for 5 minutes. If tappet noise persists, replace the ‘O’ ring seal with new seal, part number LYX000210L. NOTE: As further confirmation, air bubbles may be seen in the oil on the dipstick. Refer to Workshop Manual repair number 12.60.20 for repair procedure. In the unlikely event that the oil suction pipe is damaged replace with new assembly, part number LSP000040L which includes the new ‘O’ ring.
