To descibe the noise some more, it is a definte whine similiar to a sqare cut gear noise.
There is no grinding or rattling consistant with a collapsed tensioner. The resultant sound (after upgrade) is quite different as compared to the sound before the upgrade. Before the upgrade, I had one collapsed tensioner that was quite noisy cold.
I did not touch the ramps or chains. Just replaced old tensioners with new. I did hold the chains tight when installing the new tensioners before pulling the pins.
Do the tensioners have a one way valve that hydraulically locks them in the furthest out position attained? Meaning is it possible to preload the chain to much prior to pin pull? Or, will stretched chains make noise?
It does not appear to be the alternator - just in the chain housings. I definitely do not have a sewing machine sound either.
How would one verify chain alignment as proposed above.
Thank you,
Marlin
