[V8] T belt slip...

[Dave Saad]

I would bet on the leak being the source of the problem.  I fought a strange noise that radiated all over the front of the motor - and I think others did too - and finally found that coolant got into the bushing of the tensioner and all but glued it in place.  The coolant can come from the thermostat housing, leaky upper hose, or leaky pump.  they all drain right on top of this bushing.  In my case it caused the belt/tensioner to make an odd clack at certain RPMs.  It would come and go with temperature, moon phase, angle of dangle, or anything else to lead you off track.  If you tear it down, I would be real curious how that bushing looks.

I pull the left cover off now and then to inspect for leaks and proper movement of the tensioner.  FWIW, some of the V6 motors have a similar tensioner and similar issues.
