As you may already know, there are many problems
associated with the stock timing chain tensioner.
Here are some of the most common problems
that develop with the stock unit:
-The timing chain stretches and the guides wear over
time creating excessive slack in the overall assembly.
-When throttle is lifted after a high rpm pull, the sudden
change in momentum causes excessive slack in the timing chain.
This also causes a sudden change in oil pressure
in the stock tensioner.
-Sudden downshifts in the transmission or engine braking also
further exaggerates the slack in the chain mechanism.
-Installing higher tension valve springs and high lift
camshafts will also contribute to the problem with chain slack.
-The most common problem is the noise associated with start-up
and idling, which has to do with lack of oil pressure behind
the tensioner piston and excessive wear on the worn screw gear.
