HLA

Problem	Possible Cause	Remedy
1. Tappet noise occurs when engine started immediately after engine oil replacement	No oil in HLA	Tappet noise should dissipate from within a few seconds to ten minutes
2. Tappet noise occurs when engine started after setting more than one day	No oil in HLA	Tappet noise should dissipate from within a few seconds to ten minutes
3. Tappet noise occurs when engine started after cranking by starter more than three seconds	No oil in HLA	Tappet noise should dissipate from within a few seconds to ten minutes
4. Tappet noise occurs when engine started after HLA replaced	No oil in HLA	Tappet noise should dissipate from within a few seconds to ten minutes
5. Tappet noise continues more than ten minutes	Low oil pressure	Check oil pressure (Refer to Section D)
5. Tappet noise continues more than ten minutes	Defective HLA	Inspect HLA (Refer to page B-54)
6. Tappet noise occurs at idle after high-speed driving	Low oil level	Add engine oil
6. Tappet noise occurs at idle after high-speed driving	Degenerated oil	Replace engine oil
