When pressure switches fail and start leaking they leak through to the actuall plug in part, not around the threads...I'm gonna pick up a KA switch and toss it in today...i'm running a Greddy IM so its not hard to get to at all.9240sx wrote:If its just leaking oil you souldnt have to replace it...Try removing it and putting on some new RTV around the threads and torque it down..That sould do the trick.
