HELP, GMC 2.4L Twincam, Re/Re waterpump, now camchain slack

Off the truck topic a bit, but this newsgroup has the best techs.

All kidding aside.
This problem is a 2.4 liter GMC twin cam engine with the
TIMING GEAR DRIVEN WATER PUMP.
How do you get the timing chain tensioner (hydraulic + spring) to re-tension (bounce bask out) after reassembling the timing chain after a water pump replacement? Yup, pinned the timing gear alignment holes to reset chain timing. The chain tensioner pushed in easily with some spring tension, seemed to lock in when turned and now won't release or bounce out, even under hydraulic pressure after test startup.

You need to push the tensioner all the way in quickly and it should release and start auto-tensioning the chain. Pretty common oversight on these engines.
