-- Count the visible piston threads.

NOTE:

The visible threads are all of the threads that are located to the right of the chain tensioner housing -arrow-.

If six or fewer threads are visible: the camshaft timing chain does not need to be replaced.
If seven or more threads are visible: the camshaft timing chain must be replaced. Refer to CAMSHAFT TIMING CHAIN, REMOVING AND INSTALLING .
