Thanks for the idea. I took my stethoscope back out and did some more listening. Here is what I heard:
1. Water pump - bearing noise is a bit louder than on the PS pump or alternator. There is a metallic click in the sound.
2. Tensioner shock - At the top of the tensioner shock the noise I've been hearing is much louder than at the water pump bearing. At the bottom of the shock the noise gets louder yet and I can feel a strong vibration there. I can't see any runout of the tensioner idler pulle but it's hard to see much down there.
QUESTIONS
: Does this sound like a bad shock? a bad idler puller? or a bad tensioner? How would I check these out? So far I have tried applying pressure to the top of the shock but no change in the sound resulted.
