That would be the easiest but I'm not sure the best or most accurate. The temp sender would have to be in the oil stream, installing it above and t'd off the pressure sender may not allow enough contact with the oil. I'm also not sure at what point the oil at the pressure sensor is in it's circulation, before engine heat, during or after. Measuring oil temp depends on where you're trying to measure it. Installing a temp sender bung in the pan measures temp after it has been through the engine and heated up, but it also will give an average of oil temp including any heat loss through the pan. I wonder where race car builders put it?
i like that idea. hey thanks guysI have a remote adapter on my Ranger and one on another vehicle which allow dual filters. There is no "tap" on the part that threads onto the engine filter mount, which would be the best place for heat monitoring. They do have possible taps on the remote filter mount part, but that will mean you'll get some cooling of the oil before it sees the sensor. Some oil cooler sandwich mounts have a temperature valve (bi-metal spring) in the engine mount that automatically opens when the oil is hot to allow it to travel to the cooler, this will by-pass the filter to allow the oil to go to the cooler first after the oil is hot, then to the filter.
Ok, one thing I would like to point out is that if you are using an unmodified factory oil pressure guage, you are not measuring oil pressure. Look at the sender unit. On a 3.0, it's behind the passenger side head on the back of the engine block. If it is fairly small in diameter, it is not a pressure transducing sensor but in reality is an on/off switch. There is a fixed resistor in the circuit somewhere ( on my '93 it is soldered to the back of the cluster) that forces the gauge to read mid scale if there is more than about 5 psi of pressure. Below that the switch opens and the guage reads zero.
wow i dident know that.. thats honestly kinda stupid...... ill check into that mod.. and i did check into the adapters. but i dident know what thread a ranger was
The drop out may be because the hill climb is so steep the oil in the pan goes the the back of the pan and below the pick-up tube. You may need a custom pan.
No need to "jumper the resistor", just "T" the factory pressure switch with the new pressure sensor.
That would work, as long as you realize going into it that the guage will be reading much lower than usual. If you jumper the resistor, you will get more of a mid guage reading (if the pressure in the engine is good) and the guage will be more sensitive to changes in oil pressure.
