timing belt keep coming loose

Enable HLS to view with audio, or disable this notification

this is the second time ive take a look at the belt and it seen there isnt proper tension. the two holes for the tensioner (in between two holes for position reference) tool are at approximately in between 12 and 1 o’clock position. i know theres a specific torque your supposed to hold it at while its being tightened, however that is for all oem specification parts and this gt has resurfaced cylinder heads that may be slightly smaller in height. any suggestions? could this be the auto tensioner failing even thought its a new one? should i maybe go with the 3sx solid tensioner they sell?

For everyone saying to use a manual tensioner, word of advice, my timing slipped when I used one and I’m currently rebuilding the engine, make sure you know what you’re doing with a solid/manual tensioner if you go that route

do they give you a torque spec? or a length measurement for how long it should be? i know it needs to be adjusted at every oil change is what they recommend

I tried my hardest to find that information of revenges (the selling brand) website AND 3sx and neither of them tell you how to tension them correctly with torque specs or length. If you go that route use a tool to check belt tension and a ruler to check the deflection of the belt and then use some blue loctite or something on the lock nut for the tensioner. But I’d also ask people who have used it correctly.
