The belt looks to be in pretty good condition. I can spin the pulley with very little drag from the belt. the belt has about 3/8" flex when I deflect it on either side of the Idler pulley that is in between the cams. I think were on the same page.
Yea it has 250k on it I was just looking it over before winter. Its a friends vehicle and i'm not 100% familiar with it. It drove like a 3.0 with 250,000 miles on it. Has good idle and ok response, I believe it was pretty well maintained by a previous owner. I was just wondering if one of the cam pins may have sheered off and caused the slack.
I agree with you completely on how it can turn into a bad thing quick. I didn't think it was right by looking at it. I believe it has a hydraulic tensioner. I havnt looked at it yet. I'm not familiar with Toyotas but it seemed obvious to me. I appreciate the Information. I'll put that on my list for this project. Thanks , Jack
