A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

Failure of the valve cover gasket can allow engine oil to leak onto the spark plug wires and damage them. The engine will run poorly (misfire) if the spark plug wires fail.
