Install the camshaft thrust plate. 4. Install the balance shaft drive gear. 5. Install the timing chain and sprockets. 6. Lubricate the lifters with clean engine oil. 7. Install the lifters in the block. 8. Complete the installation in reverse order of removal.

The installation process follows the reverse order of removal.

Install the timing chain and sprockets, along with the CMP sensor.

If the camshaft is being replaced, always install new lifters as well. Do not use old lifters on a new camshaft.

Begin by removing the engine from the vehicle, followed by the valve covers and the intake manifold. Next, take out the rocker arms and pushrods, then remove the timing chain and sprockets, and subsequently the cylinder heads.

Store the lifters in a labeled box to ensure they are reinstalled in their original locations. Clean them thoroughly with solvent, checking for scuffing or wear.

Lubricate the lifters with clean engine oil and install them in the lifter retainers, aligning the flats properly. For 2005-on 5.3L models, ensure the raised surface aligns with the notched area of the retainer.

To inspect the camshaft, the lobe height and base circle should be measured to determine the lobe lift. The results should be compared to the specifications, and the camshaft should be replaced if necessary. The camshaft bearing journals should also be inspected for wear and damage, and measured with a micrometer. The camshaft lobes should be checked for discoloration, score marks, chipped areas, and uneven wear.

During inspection of the camshaft, you should: 1. Clean the lifter and camshaft with solvent. 2. Check for wear and damage on the lifter and camshaft. 3. Measure the journals and cam lobes for wear. 4. Replace the camshaft and bearings if they are damaged.
