1983-1984 S/T trucks that are equipped with the 2.0L L4 engine were assembled with a rear camshaft cover that used RTV sealant. A new improved
cover and seal have been released to replace the production parts.

The sealing surface must be cleaned, and the main oil galley plugs should be flush with the block before the cover and gasket are installed. Torque bolts
