I should know this,Oil pressure Gauge

[Freight_Train]

Ok,New problem that ain't technically a problem.....Fired her up today to make sure I wasn't stoned and didn't halucinate she ran great.Noticed the oil pressure idiot needle wasn't working.Guess this gives me a perfect reason to install the OP gauge tomorrow.Now,where is the best place to get accurate oil pressure readings?Using an autometer Electric gauge so I won't have to worry about routing a hose.

On my truck i removed the factory sending unit and tee'd in my guage there. The factory unit is located near the bellhousing on the passengers side of the motor.

good luck

I heard the best place is right at the oil filter there is a plug you can remove and use for the sending unit but that is for the mechanic gauge, I really don't know about the electric ones if there is any difference.

My oil cooler did not have that plug. The original one did but when i replaced it i was looking at the new one and the plug was not there, so thats why i put mine at the factory location.

Thanks.I'll have to crawl under there later today and see if I can find the plug on the cooler.Does it have a square head or a recessed square drive?

There is a plug farther back than the oil cooler as well. It is in the ear that sticks out just ahead of the bell housing on the driver side of the engine, pointing out, directly sideways. I put both my fuel pump safety switch and electronic gauge sending unit there and they work great.

I have my mechanical gauge in the plug in the oil cooler and it works great. I believe it is a square head that you can take out with an adjustable wrench. I can snap a couple pictures of it if anyone wants them.

I'd like to see those pics please?
the oil cooler also has a pressure switch right? any body have an exploded view of one?

mine is in the factory hole, works fine............. general question along the same lines here fellas....should i have constant oil pressure regardless of RPM's? if im idling, i have very little pressure, but if im at speed, i have normal 50 pressure.

evergreen ranch,
your motor should hold 40-70 psi of oil pressure at 2200 rpms, those are the specifications according to alldata and shopkey5. take the pressure reading when engine is warmed up.

the faster the pump spins the more oil it is going to pump (up to a point)

Most engines have less than 10psi at idle, so don't panic.

Sorry it took so long to get a picture but It's been a hectic week since I started EMT school on Monday. Here is a picture of where I put my oil line in the oil cooler, that goes up to the gauge. If you have any other questions let me know.

Classic,

For your own good I would suggest you get rid of the copper tubing for your gauge. Replace it with the nylon tube that usually is used with mechanical gauges. The copper will eventually break from engine vibration and that is not a good thing.

Better yet, get braided hose like Russell Pro Flex! The nylon is not much better IMO, if you use nylon, you will definetely want to avoid the heat from the manifod and such.
