You might check the cap. It is suppose to release excess pressure to the overflow. If the cap is bad, maybe its not releasing.

In addition to testing the pressure cap, have you carefully inspected the mating surfaces for any deformities and confirmed that you are properly torquing the housing during installation?

I inspected the cap.. it seems to release freely... Idk could be not releasing at the correct pressure...
The mating surface and torqueing are good..
I'm just not sure I trust traveling with this rig anymore...
