Is there enough oil flow at the location of the stock oil pressure switch, so that it makes sense to install temp sensor and pressure sensor with a T-adapter?
IMO, that doesn’t make sense, and, it’s unnecessary also. If you absolutely need to have an oil temperature reading, weld a bung into the pan. Oil temperature really only becomes a problem with a filled block like on a race engine.
I have a pan from Steve Reynolds SRE Inc with the 1/8 npt temp unit. My engine runs usually 180F and the oil gets in the summer on the highway & drive around 165F-185F. But when I start to Idle around, the oil gets easily up to 210F. In the night with ambient temps around 60-70F the oil is just 150F while I'm cruising around. As Larry already said, it's not worth the extra effort.
Customary to measure oil temperature in the pan, not while it's circulating in the oil galleries. Unless you're running the autobahn at very high speed (compared to USA speed limits) there's no point to dicking with oil temperature. I had a 454 in a boat that would run 300 degrees (F, of course) of oil temperature if the RPM were high enough, long enough. I discovered later that the marine water pump impeller had come apart, so that flow was obstructed and the pump was much less efficient. The replacement engine, with a fresh impeller and no blockage, won't run the oil above 220 at any engine speed. Coolant temp without a thermostat was down to about 130 from 190. I had to buy a thermostat kit to get the engine up to 160 degrees coolant temp.
Can you find an engine oil dipstick with a oil temp sending unit built in to test with ??? They say conventional oils start to break down at 250 degrees, Like Schurkey said, I have had marine engines that get close to 300 degrees before I added an oil cooler, if your oil temp is 250 degrees or higher switch to synthetic oil & test it again, then you can always add an air-style oil cooler....
oil should reach near 220 once in a while so moisture (water) can evaporate I'm having senor installed on pan just to have it and run a small micro switch and get the reading from my Trans temp gauge / single temp gauge for trans & engine oil
Thanks for your input, I think I will cancel the idea of oiltemp and just have watertemp, engine oilpressure and transmission oiltemp (pan).
