I just got done cleaning the UIM and doing the VIAS fix to save me some future headaches, but once i go it reassembled the Arm with the butterfly valves in the UIM doesn't turn as smoothly as before. it will turn but feels like it needs to be lubricated and requires a lot of force...like me using pliers to turn it. Any help on this?

 

Maybe u tightened it overspec?? Lubricate and retorque, see what happens

 

its probably the orings/clip thingys that go around the rod. its hard to explain, but its basically the only parts that touch the inside of the manifold at each port.

 

ill try loosening and what should i use to lubricate the O rings? or what would be safe to use

 

since its expose to air intake, Dont lubricate

 

I had a broken O ring for that arm....i gotta pull it out and put a new one on there.
