The coating on the back of the belt coated the pulleys, and it squealed unmercifully. Could only stand it for a couple weeks before an oem went back in. Got it from 3sx, and unsure if was the Gates as they have 2 kinds.

A collapsed tensioner would cause your mechanical timing to be out of whack too, especially when it causes the belt to be loose. You got real lucky to not lose time from the loose belt alone.Quote:

How old was this tensioner? Was it OE? Was it ever allowed to fully extend?

3k old, oe, yes it extended fully when forgetting to put the pin back when I swapped the kevlar belt out after 2 weeks.
Staying with the oem cam gears for now.

The tensioner did however extend back out when I stuck a screwdriver between it and the arm of the pulley. It remained tensioned, but I did not let it sit to see more than 10 minutes to see if it would collapse again. I assumed that it was strong enough to stay while hand turning, but collapses while engine running. Yes I got very lucky!

After looking back it was this teardown when it extended fully, and there is 4k on it.

I dump them if they extend fully. Some have had luck but I don't chance it.
I've heard that it's not the belts themselves that stretch. It's the physical distance between the gears as the metal expands and contracts with engine heating and cooling. I would think though that in theory since you set it while cold that the belt will just get tighter as it heats up and things expand.
Unfortunately I only found to put them in a vice, and re-pin in my search of the subject. I now know!
