September 22, 200619 yr Oil galleys 2.5L 1997 I have the JDM factory Oil Temp and oil pressure gauge. The pressure sender i can bolt in using a sandwich plate (rather not since it requires a differnt oil filter). Where can i put these things. I was a bit surprised to find out they are english threads. The temp sensor is 1/8 and the pressure sensor is 3/8. Pictures would be helpful too. nipper

Then you still have the idiot light working when pressure is at or near zero. I brought the pressure sender to my favorite part store and they found the right fittings for the job. I have no oil temp gauge though.
September 22, 200619 yr Hi nipper, well I have mine torn apart at the moment so no pics, but installed an amsoil bypass filter and put the pressure and temperature sensors on the bypass filter mount. Yep I had to get a stewart-warner 1/8" british standard pipe taper or something 27 threads per inch I think to 1/8" national pipe taper 28 threads per inch adapter at the oil pressure sender. Works pretty well though.
September 22, 200619 yr Author Hi nipper, well I have mine torn apart at the moment so no pics, but installed an amsoil bypass filter and put the pressure and temperature sensors on the bypass filter mount.

Works pretty well though. ok mine is 1/8npt and the other is a very sloppy 3/8, which i am going to guess is metric. SInce i love pain so much (joke) and hate things not working, i used the sandwich plate. The senders leaked, but worse yet they were dead. I need to investigate them some more. i think the temp is the 1/8npt (three wires as in a thermistor) and the larger (weighs a ton) is the oil pressure. There is also a mystery wire at the sending unit harness that may have something to do with the dead gauges. nipper
September 22, 200619 yr interesting nipper. i usually put a stainless worm gear hose clamp around the senders and the hook a ground wire to the clamp screw as poor ground as i'm sure you know will cause the gauge not to work.
September 22, 200619 yr Author interesting nipper. i usually put a stainless worm gear hose clamp around the senders and the hook a ground wire to the clamp screw as poor ground as i'm sure you know will cause the gauge not to work. i really didnt want to do that, but i mught have to. Ill have to chase back that mistery wire and see where it connects. i thought maybe it went to the oil pressure switch, but i may be wrong. At least the temp sensor will be easy to check , the pressure one i dont have the setup for. i suspect thats a metric thread, and a straight thread at that. nipper
September 23, 200619 yr I've been planning to install an oil pressure gauge in my engine compartment for a year now. You are making me glad I've been too lazy.
