T-stat cover leaking

T-stat cover leaking
Just replaced the thermostat in my 02 XK8, thought I had it all buttoned up correctly but now I see that I'm leaking from the bottom of the cover that goes over the thermostat. Those bolts only go to 9Nm is it possible that the thermostat didn't seat correctly? There's only one seal and it goes around the thermostat. I'm probably going to pop the cover back off and try again with a new seal on the thermostat but I wanted to get y'alls opinion first. As usually any help is appreciated.

Most likely it isn't seated correctly. Remove the 3 bolts and remove the thermostat. Is the seal fitted tightly around the thermostat? Make sure the wiggle pin is at the top 12 o'clock position. Wipe everything clean and then place the thermostat back in the housing. Hold the cover against it and run the bolts down snug by hand. t is important to tighten the bolts slowly and move from one to the other to keep the flanges parallel and not cocked. Once everything is snug torque in steps around the 3 bolts.
Unless the seal is torn or severely pinched you should have no problem reusing it.

Aluminum t-stat housing, just took it apart again and noticed that there is a paper freaking gasket there between the cover and the housing. Does any of our FLAP dealers carry this aftermarket gasket? I checked autozone online and got a nope. I can see where the gasket is just buggered up enough to not seal.
