What I did was screw the fitting in until you could only see 4 or 5 threads. Then I put JB Weld on those threads and tightened it down all the way. I think it may have started to strip but it's in there nice a tight. Then I put a beads of JB Weld all around the fitting and sealed it. I left a portable heater under the car to help it dry overnight. Will I have problems or will this seal it nicely??? JB Weld seems to work good unless its under high pressure or lots of drastic temp. changes. I just want to know if I did this thing right...

 

Thats how I did mine for the turbo, seems to work fine so far.

 

same thing here works great, no problems

 

it will eventually crack, JB weld is junk!

 

I've had JB Weld on my radiator for 5 years, and it hasn't leaked yet. A friend's dad used it to seal up holes in his cylinder head, and got another 100k out of it.
