So, one of the nuts that tightens the water hose into the LIM (S4 T2) snapped off and broke off the bolt sticking of the LIM. And now, only one bolt could be screwed on. I don't think there's anyway around this other than to get a new LIM.

 

Drill out the broken stud and then tap the hole or install a HeliCoil.

 

Thank you so much. I was about to get a LIM. Helicoils are so cool!
