Default Leaking Coolant Elbow

I replaced my leaking coolant elbows again on Friday night, and the cars been dry since then. Went to move it this morning and pulled out of the drive way, and backed back down, then got out to check it just in case, and noticed a good sized pool of coolant developing under the car. The elbow connection that has 2 orange o rings, the upper one, was leaking. Looked like the LIM seal was fine, but the other end was leaking.

Then as it started to warm up the drips quit. I don't get it... How does it go from dry, to all the sudden leaking a pool like that and then not leaking again. The only thing I could come up with is maybe there is a blockage somewhere in the system causing excess pressure?

Try to wiggle the elbow to get it centered in the hole. The plastic might be up against the metal causing the O ring to not seal as good.

Thanks Dan, I'll give it a try and see if I can get it in a better position. It'* hard to tell though since the leak is so random.
