Valve Lash (Clearance) Adjustment


The 4.2L, 4.6L, 5.4L and 6.8L engines do not require valve lash adjusting, because they utilize hydraulic lash components in their valve actuation systems. The 4.2L engine uses hydraulic valve lifters, whereas the 4.6L, 5.4L and 6.8L engines utilize hydraulic lash adjusters, all of which automatically adjust the valve lash. No valve lash adjustment is necessary.

Valve lash on the diesel engine is not adjustable.
