Default 4.0 IL6 Valve Lash adjustment?
Is the valve lash on the 4.0 IL6 adjustable? If so, what are the specs?

According to my manual it's not adjustable.

There isn't any adjustment. If there is any looseness in the rocker arm or arms it usually means that your lifters are collapsed!

There is an initial rocker arm settinig/adjustment, per the FSM. Usually, a hydraulic valve train does not need periodic adjustment, after the initial setting, but it's not unheard of either.
