Rocker Arm Assembly: Service and Repair
Fig. 5 Rocker Arm
1982---88 V8-255 & 302
These engines use a bolt and fulcrum attachment, Fig. 5. To remove, remove attaching bolt, then the fulcrum, rocker arm and fulcrum guide, if the
other rocker arm is being removed. Some 1982 models equipped with low profile rocker arm fulcrums (part No. E1TZ-6A528-A) may
experience excessive oil displacement when engine is operated for extended periods during high ambient temperatures. This problem may be
corrected by replacing original rocker arm fulcrums with part No. D7AZ-6A528-A.
