it's self adjusting , unless you have a million miles on it or ran it dry of oil, I don't think that's what you're hearing , What you see is the spring tension release for loosening it to remove the cams for the valve shim adjust or cylinder removal.....
from the service manual:
This is a non-return type camshaft chain tensioner.
The push rod does not return to its original position
once it moves out to take up camshaft chain slack.
Observe all the rules listed below:
When removing the tensioner, do not take out the
mounting bolts only halfway. Retightening the
mounting bolts from this position could damage
the tensioner and the camshaft chain. Once the
bolts are loosened, the tensioner must be removed
and reset as described in "Camshaft Chain Tensioner
Do not turn over the crankshaft while the tensioner
is removed. This could upset the camshaft chain
timing, and damage the valves.
Cap Bolt [A]
•Remove the spring [A].
•Remove the mounting bolts [A] and take off the camshaft
chain tensioner body.
Camshaft Chain Tensioner Installation
•Replace the O-ring [A] with a new one. •Apply grease to the new O-ring. •Release the stopper [B] and push the push rod [C] into
the tensioner body [D].
•Install the tensioner body so that the stopper [A] faces
upward. •Tighten the tensioner mounting bolts.
Torque - Camshaft Chain Tensioner Mounting Bolts: 9.8
N·m (1.0 kgf·m, 87 in·lb)
Washer [B] •Tighten the cap bolt [C].
Torque - Camshaft Chain Tensioner Cap Bolt: 20 N·m (2.0
kgf·m, 15 ft·lb)
•Turn the crankshaft 2 turns clockwise to allow the tensioner
to expand and recheck the camshaft chain timing.
