Quick question for y'all.
'99 TJ Sahara, 128K miles, no major engine repairs yet except for the exhaust manifold. Last oil change was about a month ago, with synthetic
5W30.We got hit with the cold today, and on the drive home from my mother-in-law's, I saw that the oil pressure gauge was at 80. It normally runs the 20-60 range. The engine seemed to warm up quicker than it usually did (but then it had been driven for 2 hours on the way up, and only sat for about 3.5 hours before we headed home). When I took off the gas, the pressure gauge came down to 60. As we continued driving, it slowly crept down, so by the time we got home half an hour later, it was at 60 at 2000 RPM, and 40 at idle. The engine temp stayed at 210.
Some quick research showed that this is probably the oil sending unit, but the fact that the pressure gauge dropped over the course of the drive home has me wondering - if it were a bad sending unit, wouldn't it have stayed at
80?Thanks for any thoughts or recommendations.
