[V8] Oil pressure

[Dave Saad]

Hey V8ers!
I have some memory of these IC problems. I found that the internal ribbon cables are a problem. They are made of solid conductors and seem to crack after the cable vibrates for a few decades. I fixed mine by replacing the wires with individual stranded wire. Since the cracks can happen above the circuit board, resoldering may or may not solve your problem.

And to test - the pressure sender is actually a mechanical rheostat. To test the gauge you need to apply appropriate resistance to the terminals at the sender connector. If the gauge reads correctly then bad sender.
And the sender is NLA? Is this one with two senders in one unit? ( I sorta remember that...)

About 60% of the time it reads high(5) whether idle or foot on pedal.  Then it will go to normal at idle(straight up) and go up to 5 with a tap on pedal like it’s supposed to(or like Lago’s done the entire time I’ve owned it).  Guessing it’s the sender, and since they’re NLA, I just don’t pay attention to it.  I do however feel better when it’s reading right.  If you verify that you actually have low pressure, then what?  I know you’re in for the long haul like me, but first thought would be oil pump….doesn’t sound fun.  Worn main bearings/screwed.  If you didn’t clean/resolder all the connectors on that IC, then I’d do that before anything else, as doing that made everything else work the way it’s supposed to and am confident my gauge issue isn’t in the cluster(soooo many of those solder joints were loose).  Do you have a spare oil sender?  Both my spare motors are sitting on very squished out tires and pretty sure I removed one of the senders to put on one of the cars, but might have a spare if you don’t for testing…..Tom
