I've got a engine whine that I can't locate on my '87 Maxima with 65 K
miles. The whine started about 1K miles after service of the t-belt,
trans fluid change, and power steering pump hose replacement. I've
been all over the engine with a stethescope and still can find it, but
sound like it is coming from under the t-belt cover. It happens in all
trans positions, at any temp and increases with engine speed. I have
removed all the accessory belts to see if was the water pump, ps,
alternater, idler pulleys etc. Oil pressure looks to be ok at the
spec'd rpms. I replaced the timing belt and tensioner pulley at the
proper tension. I found that the dealer installed the timing belt too
tight and I thought I found the problem. I checked the t-belt covers
for signs of rubbing. Still no luck. Anyone have a oil pump go out or
have a bad torque converter? Any other ideas?
TIA

When stealership 'service' swaps new round teeth belt on squared teeth sprockets, billin is ensured and customer & engine whinin the big result. At least they play dumb in findin the noise source... DIY swap of squared belt to squared teeth helps in this problem. [=my max story
That noise doesnt kill however; previous owner tells that this max whined well for 5yrs, 30k
(I know I am negative while the situation isnt really so bad at stealerships: theres at least one guy in nissan-europe who is able to service maximas...

My guess is what ever belt was serviced that is the driven item causing the
noise. The load on the driven item has been changed.

Tensioner bearing noise: 1. do NOT change and it breaks due to ageing 2. do change and new bearing is faulty = roll dic
Tst loosen the accessory belts to count them and their tensioners out..
