Fellow abodies, I am in need of some guidance. I am restoring my fathers 70 Duster. He bought it when I was 2. Unfortuneately he passed away in 2004. I have had it stored since then. I brought the car from his place to mine , once home I cranked it up and let it run for a minute. I had zero oil pressure so I shut it off.

I brought the car out of storage this past fall and have been getting it ready to ride with the thought that I had to replace the oil pump. Well, I did that and still no O.P. I dropped the pan and checked the pickup, no problems there. I primed ccw with an electric drill. Still no pressure. I removed the sending unit and put a manual gauge in , tried the drill still no pressure. lastly I remove the manual gauge and tried the drill, the oil just oozed out of the sending unit hole. Seems like it should have squirted out.
Any suggestions?
thanks,
Johnny Dop
 
Are you sure the hole at the sending unit isn't restricted?

Sounds like the oil has thickened up in the passages if there is no restriction.
 
Ok, I am going to put a K/N on tomorrow night. After reading some of the forums I have found out that I currently have the Fram filter of death on the car.lol. Can it be that simple
 
As far as the sending unit hole, it is open enough for me to look into with a flashlight. I guess that is open enough.
 
I have them in a pdf on the welcome wagon, I am still trying to figure out how to post them when they are open. Give me a few and I will try
 
Lets see.

Wow it worked!!!Now if I can get the oil pressure to work, I'll be cooking with fire!
 
The oil filter will not stop pressure. Make sure you have the proper gasket between the pump and block, as well as the little "O" ring on the snout of the pump.

Remove the filter which will remove all "head" pressure against the pump. You should be able to get oil out of the filter mount in a fraction of a second with the drill.

If not, pull the pump off the block, and either immerse in oil and turn, or pour oil into the pump and turn it

Then fill the filter, install, and try to prime. If the pump is primed, you should immediately feel pressure against the drill
 
Thanks, that is about the plan for tomorrow. First my buddy Joe and I were going to remove the filter and use the drill to see if we shot oil out of the pump. Then put the filter back on and try again with the drill for pressure. If not , then pull the pass side valve cover to check the pick ups and lifters. Does that sound good?
 
Are you sure a lifter hasn't pop out of the hole. It won't have any OP if it has. Since the car sat, it might have a stuck valve which in turn bent a pushrod which allowed the cam to knock a lifter out of the hole. Pull the valve covers and look for a lifter out of the hole.
 
Mopar 367, yes that was one of the first things I picked up on while cruising the site. Thanks for your input. Will I be able to see if the pick up is bent, and will I be able to see if a lifter came out when I remove the valve cover?

Yes with a flashlight there are openings in the heads so you will be able to see all 16. It might be obvious when you remove the valve covers. Push rod stuck through a rocker arm or bent push rod.
 
Yes if your lifter came out of bore your push rod is most likely bent too. So you will have a loose rocker arm on that particular lifter. As for if your oil pickup is bent, put like a clean piece of wood that is about 1/2" thick in pan. Your pickup should be about 3/8 inch off pan bottom. So with the 1/2 piece of wood in pan it should just almost sit flush on bottom of block. Also some people use plastercene in a baggie to squish and determine pickup height.
 
yes , I meant to type push rod, I checked the pickup last night, cleaned it out , checked for cracks, all was well and reinstalled.
 
Roy, I hope that is the case, I was beginning to worry about my cam bearings being shot and I can't afford to pull it and rebuild it right now!
 
It's very common for the oil pump to lose its prime from sitting so long. PUt some oil in the filter and try it again. If there is no oil film between the oil pump rotors, sometimes they will not pump. Seen it happen a good bit.
 
Tks Rusty, hell we even packed the new pump full of grease to try to help prime it.

If that's the case, something is bad wrong. As I said earlier, pull the filter and see if you get oil out the filter mount. If not, the problem is

wrong direction (they turn ccw)

busted gasket/ o ring(s)

cracked pickup tube

NO OIL IN THE PAN!!!!
