If the ticking noise persists, proceed with step 3.
3.
Let the motor run at idle and use a stethoscope or Steel screwdriver to determine which bank is noisy. Once you have determined the location, turn
the key off. (Figure 1)
4.
Remove the cylinder head cover on the noisy bank.

Inspect each rocker arm for clearance at the valve (when the rocker is on the base circle of the cam and the valve is closed). The noisy rocker arms
are the ones with clearance. (Figure 2)
