12562818 - Zz4 Timing Chain Cover (Composite Plastic)

This new design cover is used on all ZZ4 crate engines, and will bolt to any small-block Chevrolet engine from 1995 through current model except LT1, LT4 and LS1. Technical Notes: Use RTV sealant to seal new timing chain cover. Not recommended for use with short leg water pump because there is no clearance between back of pump and the cover. Use chrome cover P/N 12342089 or early model sheet metal cover P/N 12523317 for short water pump application.
