• Q: How to replace the Lash Adjusters on 2003 Chevrolet Corvette?

  A: The valve lifters replacement process starts with removing the Cylinder Head while also eliminating the valve lifter guide bolts followed by removal of valve lifters and guide. Use an equivalent tool as the valve lifter remover (J3049-A) to dislodge stuck valve lifters because of gum and varnish deposits. You should organize or mark the guide components for proper reinstallation once the valve lifters are removed from their position. Perform an inspection of valve lifter assemblies then clean both valve lifters and guides for new installation. Make sure to reinstall re-used valve lifters into their original positions in the engine. Add clean engine oil to both valve lifters and engine block valve lifter bores then place valve lifters into lifter guides while aligning top lifter flat section with guide bore flat areas until the lifter reaches the bore limit. Install the valve lifters and guide on the engine block while ensuring a 12 nm (106 inch lbs.) torque setting for the valve lifter guide bolt. Installation of the Cylinder Head concludes the process.
