No oil pressure (Page 2/4)

George, thanks for your reply.

I will take everyone's advice and verify oil pressure before jumping to any conclusions. Thanks again for all of the suggestions.

I'll update this weekend when I can get back to the care and try a few things.

The likelihood of you accidently snagging a oil sending gauge wire, or something coming dislodged when the pan was removed, in my opinion seems much more likely.



That's exactly how I feel about it.

But yeah, you don't want to make assumptions either way. Temporarily attaching an aftermarket mechanical oil pressure gauge (if nothing seems obviously wrong with the factory setup) to confirm oil pressure is a good idea.

I just hooked up a mechanical gauge, and still no pressure. Anyone have any thoughts?

Well damn.

Before dropping the pan, I'd try what is suggested below. I use a modified junk distributor (powered by a drill) for this purpose.

Remove the distributor. Get a drill with an extension and a socket to match the hex size of the distributor shaft and with the drill spin the pump until you get oil pressure.

I'm guessing you did not remove the pump, while the pan was off.
But if you did... IIRC, there is a driveshaft that goes between the distributor and the oil pump.

I would be inclined to pull the distributor, and use a prime tool to pump up the oil pressure. The pump might be trying to start without a prime.

Yes... maybe that oil pump driveshaft is missing!

Willy, did you accidentally pull the driveshaft out with the distributor... and not put it back in?

I don’t believe so, I didn’t remove the Distributer, and I don’t think I touched anything when I removed the oil pan. But obviously I messed something up.

Perhaps you bumped the oil pickup tube when fiddling around with the pan. Now it is sucking air

Thanks for all the help on this thread. I am going to try to prime through the distributor, and if that doesn't work it's back to pulling the pan to see what's going on. Unfortunately it's going to be about 4 weeks until I can get to it, so I will have an update here then.

Thanks again.

Willy, did you make any progress this past weekend?
