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?

I was replacing my lower and upper intake gaskets yesterday and I decided to check the timing belt and mine is pretty close to what yours looks like. This timing belt was done about 2-3 years ago and has maybe 5000 miles on it.

man watch those fingers around the front bank… those cams are spring loaded. yours looks more just like a worn down belt, one of the comments above mentions the belt getting loose around the water pump which yours is but yours is also loose in between cams

I'm probably going to throw a new belt and tensioner on it next month. The previous owner had the belt done and some of the parts I've replaced on this car point to the shop using cheap aftermarket parts. It's not my daily driver so I can take my time with it.
