Chrysler (AMC) Camshaft Timing Pin Failures
Some 1977-80 Chrysler (AMC) six cylinder passenger car engines may experience camshaft timing pin failures that will result in incorrect valve timing. The pin is located between the camshaft and timing gear, and may shear or break allowing the camshaft to slip.
Replacement or removal of the camshaft is not necessary to repair the problem. After the timing cover is removed, extract the old pin from the camshaft by using a self-tapping screw on spring type pins or a drill and a stud extractor screw on dowel type pins.
To prevent the camshaft from pushing back and breaking loose the rear camshaft oil plug, wedge the camshaft by removing the fuel pump and inserting a pry bar or large screwdriver through the fuel pump opening. The replacement spring pin is AMC part number GM456384.
