Hey everyone, I haven’t been on in a long time so here’s a quick update , I’ve been traveling way to much. I finally got my firewall painted and my engine dropped back in. (pictures/ video hopefully tomorrow) Nevertheless there’s always issues. I primed the engine and saw oil reach the head seeping out of the rockers, so I started the engine and got it to idle. Man it sounds mean and awesome. It hasn’t been back in and running since I graduated high school in 07.



Even though I saw oil reach the rockers my gauge didn’t ready any pressure, so I wanted to make sure I didn’t put the oil sender in a bad port per say. I installed the sender in the front driver side down near where the fuel pump would be.



I know I have a bad water sender out of the box because it shoots to 250 as soon as it gets power to the gauges. Im hoping I don’t have a bad oil pressure sender as well. Also there is no Teflon tape on the threads of the sender its bare to the block. Any ideas guys?

From reading your post it seems you are using an electric oil pressure gauge. If you touch the wire going to the sender to earth does the needle of the gauge move. If not you don't have power on the sender. If it moves it would suggest that your sender is faulty. It is not unusual for the senders to get a sliver of Teflon inside the hole and block the sender from reading. You could always just get a mechanical gauge and screw it in where you have the sender just to check that you have oil pressure.

When you unscrew the sender you should get a little oil run out of the block. If not check there is oil there when the engine is running. Just give it a crank over with the oil lead off and oil should spurt out. If not try one of the other positions on the gallery. Just make sure you plug the outlet you don't use.

Yes you are correct it is an electric unit. Tomorrow I will definitely try grounding out the gauge and see if it reacts.

It's a long shot, but I've seen this happen once.  I was helping a friend sort a lack of oil pressure problem in his new engine he had instlled in his '56 Bird.  After all the usual checks, I just idly stared at the bottom side of the engine, trying to think of something else to check.  Then I spotted it.  He has screwed the oil prossure switch into the water petcock hole!

As you know, oil to the rockers mean you have or had pressure. The electric gauge set up in these machines could be erratic when new or nearly new. I replaced the original OP gauge set up with a mechanical gauge when my '56 was nearly new, due to the long time erratic behavior of the electric gauge.

well i found the issue when i realized non of the gauges were reading... for some odd reason i forgot to add a Grounding wire to the gauges. so they would all jumped a little bit, and since it was cold and i knew i had just a little fuel i thought they were reading correctly, but when i added another 6 gallons of gas and the gauge didn't adjust i knew there was something i was missing.



As promised heres some pictures and videos

Nice clean engine bay, where are you running wires for headlights etc? under the fenders? and the gas line coming up the back of the engine, just remember rubber line can not be more than 6" long if you bring it to a track.

What are the headers? They look a lot like a set of early Headman's that I have had forever. They also bolt to the original head pipes which makes instalation simple.
