Oil pressure...
I tried to search on this topic but it won't let me because the word "Oil" is too short.
So here's my dilemma...
I just purchased a 1988 F-250, 302ci motor, with 81,000 miles. I've noticed the oil pressure gauge reads a little on the low side even when driving down the road. The motor has plenty of power, it's not making any noises, it's not smoking, it's not even leaking...
A friend of mine (who used to work at a Ford/Dodge dealer) says that the sending unit or the gauge is a known problem and that the motor probably has decent pressure.
Anyway, I'm going to find a manual gauge and test it, but I wanted to know if he is right about this, and see if anyone else has had a similar problem.
Thanks,
Dave.

the dash gauges are electric, the signals are sent from senders that dont like heat and thorough some little poorly insulated wires. if it reads anywhere in the normal zone it's fine, if it read L al the time but makes no noise don;t worry about it. Get an aftermarket gauge set and forget about the dash,

Dave, I agree completely with pfogle. Our 80's models trucks are notorious for having inaccurate guages. A decent aftermarket guage is cheap peace of mind. As far as oil pressure goes, the guy that did the machine work on my 351W when I rebuilt it is considered to be one of the best engine guys around. He says that as long as you have 10 psi for each 1,000 rpm you're good.

I have both a mechanical and the dash guage hooked up, and the usually nowhere close to accurate. I've had it on the n with 75psi. So as long as your sash shows some pressure you should be alright.
