would it do any harm if i removed JUST the omp Rod, and ran premix without removing the actual system? because my jspec s5 air pump mont clear without it removed. and im already premixing... any ideas?

 

That would be okay as a temp solution, couldn't hurt to block off the OMP, remove the lines and oil injectors and plug the holes with AN plugs. That's what I am doing right now because I couldn't hook up the oil pump connecting rod to the FD throttle body I'm using. As long as your premixing you'll be fine.
