SUBJECT:
METHOD OF REMOVING PUSH ROD COVERS ON 2.5L L4 ENGINES
MODELS AFFECTED: 1985-86 SKYLARKS, CENTURYS AND SOMERSETS WITH 2.5L ENGINE (VIN CODE R OR U)
A method has been developed to remove the push rod cover from 2.5L L4 engines without damage, using components already on the engine.
1985-86 Centurys 1985 Skylarks (VIN Code R)
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, unscrew the studs until the cover breaks loose.
1986 Skylarks 1985-86 Somersets (VIN Code U)
To remove the cover, repeat the above operation using two standard 6 mm nuts instead of two original nuts on #2 stud. This stud is too short to use nuts
with washers.
