Subject: [T3] Engine oil temp?
I do realize most don't use added gauges. The VDO oil pres/temp/voltmeter.
I replaced the oil pressure and temp gauges and so far the oil pressure
sender. It's mounted on a square profile steel elbow to the cooler with a
banjo fitting , don't recall if that came on my engine.
The pressure gauge read 10 PSI key on engine off, faulty gauge, Senders
ohm readings were all over the map , faulty.
Have a new temp sensor that reads fairly close.
Here's the deal . The oil pressure readings are a little higher than the
10 pSI per 1,000 rpm rule. I don't know who made the rule but I do know VDO
gauges are not 100% accurate at least to say they may not be.
7 mile drive 81 * idle PSI 25 . Oil temp read 180* . Shut it down for an
hour temp dropped to 140 oil pressure back up to 35 pSI 1,000 RPM the
highest it gets @180 * 40 PSI. Drove home 7 miles ambient 85*. read about
the same. Shut it down for 10 minutes oil temp was 190* .
The temp will rise yet it almost seems as if the cooler always has oil
flow.
