Position camshaft so that the base circle of the lobe is facing the cam
follower of the valve to be checked.
Using Valve Spring Compressor T88T-6565-BH or equivalent, slowly apply
pressure to the cam follower until the lash adjuster is completely collapsed.
Hold follower in this position and insert the proper size feeler gauge between
the base circle of the cam and the follower.
If the clearance is excessive, remove the cam follower and inspect for
damage.
If the cam follower appears to be intact and not excessively worn, measure
the valve spring assembled height to ensure the valve is not sticking.
If the valve spring assembled height is correct, check the dimensions of
the camshaft. Refer to Specifications.
If the camshaft dimensions are to specification, remove, clean and test the
lash adjuster. Refer to Section 03-00.
Install the lash adjuster and check the clearance. Replace damaged or worn
parts as necessary.
