Swampy Posted April 20, 2018 Share Posted April 20, 2018 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 Link to comment Share on other sites More sharing options...
DirtyComanche Posted April 20, 2018 Share Posted April 20, 2018 Take the engine mount off for access? Pound in a pipe extractor and turn it with a wrench? Link to comment Share on other sites More sharing options...

DirtyComanche Posted April 20, 2018 Share Posted April 20, 2018 It looks thin enough you might be able to collapse an edge of it with a punch, then turn it out with a pair of pliers. Link to comment Share on other sites More sharing options...

The thread would either 1/8 or 1/4 NPT; same size as the oil pressure sensor. Pipe thread taps are tapered so it should be easy to start. Link to comment Share on other sites More sharing options...

They will go into the hole but I can't get a wrench, drill etc behind it because the motor mount is in the way. And I don't know how I would move that mount out of the way Link to comment Share on other sites More sharing options...
rokinn Posted April 20, 2018 Share Posted April 20, 2018 Can you get a ratcheting box end wrench on the tap and just re-tap the hole threads? Or extractor, may work, but I've never had much luck extracting rusted broken parts. You could put a die on the new part to know what size the threads are! Just a thought, worth a shot, maybe?

HOrnbrod Posted April 20, 2018 Share Posted April 20, 2018 Yeah, bummer. Maybe unbolt the engine mounts and raise or lower the engine w. a jack & block of wood under the pan enough to clear? Link to comment Share on other sites More sharing options...

And I don't know how I would move that mount out of the way Support the engine with a floor jack and pull the mount out piece by piece. The pipe nipple extractors are low profile and you should just be able to pound one in and put a wrench on it. Alternatively Snap-On sells some small extractors for not too much, Google search REX114A for an example. Link to comment Share on other sites More sharing options...
DesertRat1991 Posted April 20, 2018 Share Posted April 20, 2018 The temperature sensor on top of the engine near the firewall is brass and hollow as well. I accidentally snapped it off and was pretty much left with your situation in the picture below. I was able to tap a short allen wrench into the hollow shell and the hex points were able to get enough bite in the brass to spin out what was left. Good luck.

HOrnbrod Posted April 20, 2018 Share Posted April 20, 2018 Not that it helps you Swampy, but the HO engines have the oil pressure sensor mounted on the oil filter adapter; real easy to get to. Sometimes I think the Renix design engineers were a bunch of sadists. Link to comment Share on other sites More sharing options...

I'll also suggest some key stainless steel items. and coating the floor. and some extra paint in the bedsides. and... Link to comment Share on other sites More sharing options...
sinkrun Posted April 20, 2018 Share Posted April 20, 2018 Are you using a old style long easyout/extractor? Snap on and mac have short ones around 1 inch maybe shorter easy outs that should do the trick. I can dig mine out and get you A pic if I can find them.

mjeff87 Posted April 20, 2018 Share Posted April 20, 2018 Long time ago I snapped off the MAT sensor flush with the intake manifold on my 2.5, much in the same way as your OPS there. I ended up using a set of flat fluted extractors to get the remnants out. I just pounded one into the remains and it spun right out using a small crescent wrench on the end of the extractor. You might try one of those if all else fails. Jeff edit: like these.....https://shop.tifco.com/Catalog/id/11836 Link to comment Share on other sites More sharing options...

omega_rugal Posted April 20, 2018 Share Posted April 20, 2018 i would use a thin saw to carefully cut it from inside, the use needle pliers to extract it... Link to comment Share on other sites More sharing options...
Jeep Driver Posted April 20, 2018 Share Posted April 20, 2018 This is a oil passageway, anything but an extractor is asking for trouble. NAPA sells a decent 4pc extractor set for about $15, it's good. Link to comment Share on other sites More sharing options...
Swampy Posted April 21, 2018 Author Share Posted April 21, 2018 So this is where I am at right now. I went to homedepot and bought the pipe nipple extractor set because they are shorter than the extractor I had. And I bought a new fitting being optimistic. But still no dice, the extractor set is perfect if I had enough room to hit it with my little hammer. So back to square one. I also tried to take the engine mount off but my ac compressor is in the way. Just in case people need part numbers (optimism) The brass fitting And some humor for my pain Link to comment Share on other sites More sharing options...
