Hey guys, as some of you may know my oil pressure sending unit fitting broke flush with the block and this is a write up on how to get it out. Yes there are several ways to get this fitting out, such as pulling the engine, removing the engine mount etc. This is what worked for me and can be used as a reference for other 2.5l renix owners. This problem started when I swapped my cluster from the dummy lights to a full cluster. The oil pressure switch ( which turns on the dummy light if oil pressure goes down) does not work with the full cluster. I got the oil pressure sending unit and it is a direct swap, so i thought it was going to be a 20 min job at the most. As I am trying to loosen the original switch the fitting it screws into breaks flush with the block. After singing like a sailor, i started scratching my head. Attempt #1 I thought about using a 5/16 extractor bit. The bit fits into the hole but without removing the engine mount there is not enough room to be able to get a drill to spin it out. Attempt #2 I ran to Home depot with the advice of some of my fellow members and got a set of pipe nipple extrators These would have been perfect if it fit into the hole of the fitting. It would work beautifully but since a hammer doesn't fit to tap in the extractor. Attempt #3 So the next attempt was getting a small metal cutting blade and modifying it w/ an angle grinder to fit into the fitting Before cutting away at the fitting, I removed the alternator and the ac compressor Covering the blade in grease carefully cut 2 grooves into the fitting on opposite sides, either top and bottom or left and right. Once the grooves are cut get yourself a flat head screwdriver (one that is just as wide as the fitting) slide it into the grooves and carefully back it out

Hey guys I was wrenching on the jepp today and nothing good happened. The plan was to go in and remove the oil pressure light switch in favor of the oil pressure sending unit I have for the gauge to read properly. As I was trying to take the old one out *SNAP* the 90° brass fitting snapped at the block. I am trying to figure out what to do. I have tried an extractor bit but the drill doesnt fit the the space and the engine mount is in the way. I will post up pics soon

Hello again, a few of you recently helped me out with my '90 Cherokee. On the same vehicle( 4.0 5spd), the oil gauge doesn't read anything, though I'm almost positive the oil pump is still good. It died on a trip this winter. I tried ohming it out, and got erratic readings. Also tried using another working sender from an MJ, and I still got no gauge action. I'm curious if the sender feeder, or whatever it's called, can get plugged since it's only the size of a pinhole? Only idea I got.
