Unbolt the camshaft sprockets from the camshafts, ensuring not to let them rotate, and mark each sprocket before removal to avoid mixing them up.

Disengage the camshaft sprockets from the timing chains and support them with wire to prevent falling into the timing chain cover.

Subtract the outside diameter of each lifter from the inside diameter of the lifter bore and compare the difference to the clearance specified in this Chapter. If both the lifter and the bore are within acceptable limits, this measurement should fall within tolerance. However, if new parts such as lifters or the lifter guide assembly (SOHC) or the cylinder head (DOHC) have been changed, this clearance may no longer fall within the specified limit.

Inspect the camshaft and lifters before proceeding with installation by placing the lifters and shims back into their original locations.

Avoid laying the lifters on their side or upside down to prevent air from being trapped inside; they can only be laid on their side if submerged in clean engine oil.
