Valve Lifter Installation

WARNING: This page is about a different car, the 2003 GMC Envoy XL and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: When using the valve lifters again, install the lifters to their original locations.

If camshaft replacement is required, the valve lifters must also be replaced.

Lubricate the valve lifters and engine block valve lifter bores with clean engine oil.
Insert the valve lifters into the lifter guides.
Align the flat area on the top of the lifter with the flat area in the lifter guide bore. Push the lifter completely into the guide bore.
