Notice: Ensure each valve lifter is filled with clean engine oil and the valve
lifter does not tip over (plunger down) before the installation of the valve
lifters. The loss of oil in the valve lifter lower pressure chamber or the
dry stroking/cycling of the valve lifter plunger will allow air to travel
into the high pressure chamber of the valve lifter. Air in the high pressure
chamber of the valve lifter may not be purged causing extensive engine component
damage.
- Inspect the stationary hydraulic lash adjuster (SHLA) in the following areas:
| • | A plugged oil passage (1) |
| • | A scored or worn camshaft follower pivot area (2) |
| • | A damaged or broken retainer (3), some applications |
| • | A severely scuffed or worn SHLA body (4) |
- Replace the SHLA or SHLAs as necessary.
