I'm trying to get an oil temperature gauge rigged up, and it's all done except for the placement of the probe. I've completely ruled out drilling into the oil pan, and the oil level sensor has already been used for a pressure gauge. My two options are thus. I could acquire a cross to replace the tee I put on the level sensor, or I could drill through an oil drain plug and thread the probe through there. Has anyone done this before? Having the probe in the drain plug will make oil changes a pain in the ass, and the probe is pretty vulnerable down there. But then, I'm not sure I have room for the cross up top. Has anyone done this before? Any advice is appreciated! Thank you!
