Somewhat recently acquired an 87 GT and have been fixing it up. The old oil pressure sensor leaked so I replaced it and now it informs me I have low oil pressure (around 15 at idle and 30ish highway cruising). No knocking or bad noises just yet, but I'm hoping to get ahead of that. I've seen lots of conflicting info out there, some say it's an easy job that lasts a long time, and others say that the high-volume oil pump destroys the bearings. I'd just like some accurate information and if any of you have a good source for these parts assuming it's worth doing.

What oil viscosity are you running?

Did you check pressure with manual gauge?

I have not. Is this a necessary step? the sensor is brand new.

New or not, you're sending the reading through 30+ year old wiring, connectors, etc. Like mentioned above, get a manually operated oil gauge. Add to your buggy a threaded tee, nipple & a plug. I believe 1/4" is the size. The plug is to plug the hole where the gauge will be if you don't want to leave it installed permanently. With both new oil sender and new mechanical gauge installed you can compare the two readings anytime.
ps: I recall some bad gauge readings got 3 Mile Island into some trouble in 1979. Ask me how I know.

It is not necessary unless there is a problem. Since you have one I would try this before tearing the engine apart to replace a bearing.[This message has been edited by fredtoast (edited 06-26-2023).]

Don't do that unless never drive in Winter.
10W anything maybe "rated" to ~ 0°F but doesn't like being push to cold or hot limits.
Yes, what he said, Do Not trust any Dash meter/gauge. Not even for new cars saying oil or temp too low or high.

I think that depends greatly on where someone lives.

How about 5W-40 or 5W-50 then? Or maybe 0w-40, 0W-50?
