A method has been developed to remove the push rod cover from 2.5L L4 engines without damage, using components already on the engine.

PUSH ROD COVER STUDS:

To remove the cover, unscrew the four nuts from the cover attaching studs, reverse two of the nuts so the washers face outward and screw them back onto the inner two studs. Assemble the two remaining nuts to the same two inner studs with washers facing inward. Using a small wrench on the inner nut, on each stud, jam the two nuts tightly together. Again using the small wrench, on the inner nut, unscrew the studs until the cover breaks loose.

After breaking the cover loose, remove the jammed nuts from each stud. Remove the cover from the studs. Examine the stud and rubber washer assembly and replace if either stud or washer is damaged (See Illustration for Part Numbers). Re-assemble the two studs to the middle two positions and torque to 10 N-m (90 in.lb.).

Use applicable labor operation number and labor time.
