2000 Jeep Wrangler Question: adjust valve lash
Answer #1Johnny Mopar April 13, 2009, 17:43Master
There are no Valve lash adjustments on either 2.5L or 4.0L engines. Remove the rocker arms, clean and inspect the threads in the head casting, Use NEW FACTORY bolts. Install with Blue or Red LOCTITE and torque to spec. Tighten the capscrews to 28 N·m (21 ft. lbs.) torque.
