Kinda embarrassing, but i didnt pay attention to the old Oil pressure sensor when i removed it. The new one is not bottoming out. I am not sure if it is supposed to or not. I have about a 1/4 inch gap between the base (flat part) and the block. Although its definitly got more than the 16 inch pounds of torque on it. Mind you, this is not an oem sensor, dimensions are not the same, but the threaded portion was pretty damn close. I did start the engine, and the light went out and i didnt notice a leak in the 5 minutes i ran it. I'll keep an eye on it, but just hoping for someone elses thoughts who have changed it before.
