To I was setting my timing and I removed my tensioner in the process. Now after reinstalling it the chain is slack. Here are before and after pictures.Before:After:Its almost like its not strong enough to spring back like a notch or two now. Should I replace it? I unistalled it then reinstalled it and its still the same.

I wouldn't worry about it. Most of the pressure from the tensioner is from oil when the engine is running. I'm also assuming that that is right after you set the cam timing, and before you turned the engine over at all?

I set the timing then reinstalled the tensioner then rotated it and every time it hits tdc its slack.

Is there a way to manually make the tensioner tighter?

Also just now I was rotating the motor a few rotations and notice something weird. Everytime I hit tdc the chain would be tight but then I could watch it slowly droop down. What ever could cause that I think is my problem. But I dont know what would cause that.

The tensioner is oil pressure based. It will go away after you start the car. The slack comes in from the valve springs pushing back on the cams
