I posted a couple days ago about having no oil pressure. Had the car out and everything was fine. A couple days later I started the car and zero oil pressure. Was suggested that I check the shaft that turns the oil pump. Pulled that apart and it looked good to me.(see pics) Got a priming tool and hooked it up to the cordless drill and had my wife video the gauge. It when up to 20 and drill needed to be put on higher setting. It went up to 40 psi which it normally runs at. Put everything back together and it ran fine, 40 psi, took it down the street and it was fine. Two days later I got my classic motor oil delivered and changed oil and filter. Started it up and zero pressure. Pulled distributor and gear out. Tried to prime it (counterclockwise) and it would not prime. Dipstick showed full. Also put oil in new filter before installing. I guess my next thing to do is drop the pan and check pickup and maybe replace the oil pump. I am not a mechanic and can use any suggestions anyone has. If anyone is in the Baton Rouge area I can use a good mechanic. I will attach some pictures to see if anyone sees anything. I also pulled the valve covers and everything seems ok in there Thanks Jim a.jpgb.jpgc.jpgd.jpge.jpg
 
I take it you have no oil up to the rockers ? If you do, it's possible to have a faulty oil gauge system. Gauge, sending unit or related wiring. I'll give you a little tip. Pack Vaseline in and around the oil pump vanes, when ever you replace, or just disassemble the pump. You will achieve pressure much faster. And don't use any other type of grease, the pump won't prime. Ask me how I know. Keep us posted.

When I primed it I had pressure and when I started it I had pressure. I just don't know how I can have oil pressure, park it for two days, change the oil and filter then have no pressure. Is there anyway I can upload a video from my phone to this site. So why wont any other grease work besides Vaseline. Thanks

Any grease will work, including oil, but an engine assembly lubricant is best as it will dissolve in oil. I like to pack pumps with white lithium. I squirt it in, turn the rotors, and install pump. Engine assy greases like white lithium, assy lube, etc are better as they dissolve in the oil. Regular grease won't or is difficult to do. On a side note, I don't use Vaseline as it won't necessarily dissolve in the oil.

As far as loosing oil prime, what kind of oil filter do you use? Does it have an "Anti-Drainback" valve in it? I do know slant six engines require it as the filter is upside down, whereas the RB is on its side. If the pickup was bad, it should be bad all of the time, not at selective times.
 
Jim, take the oil filter off and then spin the pump up again C/C with your drill motor to prime the pump, should come right in. loosing prime and /or drainback...........? What filter are you using. Is guage mechanical or elec. Many oil systems need to be primed up this way when the pump is dry. Oh yeah,might want to put down a pan under the pump when it primes up, then put filter back on. good luck

I have always used a wix filter. This time I have a Nappa filter. The gauge is mechanical. Right now I have drained the oil and have the car up on jack stands. I was planning on dropping the pan as soon as I have a day off. I also dropped the steering link so I can hopefully drop the oil pan. Maybe I should just buy a new pump first. Thanks

Ask the parts supplier to check into the filter specs. Most good filters have them, but there are some that don't.
 
Might want to look at the oil pump check valve. If it's leaking, or hung up...no oil pressure.

With your valve covers still off, but oil filter on, try priming the oil system. You should get oil up to one side, or the other, at the rocker arm shafts. Normal deal is get oil to one side, have to rotate the engine a little, to get oil to the other head. If you get oil at the rocker shafts, you should be getting oil to the oil pressure port, where the gauge gets it's reading.
 
Check pick up tube and block to make sure you do not have a point between oil and pump where air can be introduced to system.

Since I don't have a day off for a while I ordered a new pump and some Wix filters and I will try a new pump before dropping the pan. Ill also take the filter off and try to prime it. The reading comes off on the top behind the carb.

I will try that after I put new pump on. When you say check block, what block do you mean. Thanks

Hmmm...good luck with that! Oil goes from pan, through pick-up tube, FILLS the filter, and through the pump to the motor itself. Put the filter on.
 
I believe it goes through the pump first and then through the filter, but I have been wrong before.
 
all those wix and k&n filters have serious drain back issues but should work once they're full of oil oil.
 
I used axle bearing grease just once, and had no oil pressure. Cleaned the pump of the grease, used Vaseline and had immediate oil pressure. I think the grease first used was just to heavy. I rebuilt a number of engines over the years, both professionally and as a hobby. Not that I'm no ways an expert. I just do what has worked in the past

As far as no oil pressure, changing oil should have to bearing on it. And I yet ever to see an oil filter be the problem. Pull a valve cover off. Ether prime the engine by mechanical means or run the engine. If you see no lubrication at the rockers, then you have a problem. My money is on a faulty oil gauge. This is why I use a light as well as a gauge. Good luck.
 
Believe your right IQ52...just had it backwards. Lol, I get that way sometimes. Still the fact all the pump will do is dump oil on the ground, if a filter isn't there.

All I've ever used on pump assembly is Lubriplate.

Keep us in the loop Jim. :thinker:
 
Here is the video when I primed the oil pump. It went to 40 psi. [video]https://m.youtube.com/watch?v=96qeFXFc2d0[/video]

This video is when I started the car. I took it around the block and it ran fine. Two days later I changed the oil and zero pressure. I could hear it start ticking. Pulled the distributor out to prime it. Zero pressure. How can I have pressure then change oil and have zero. I put oil in filter also. Looking forward to suggestions.

Just thinking out loud. Assuming no major oil leaks anywhere.

You showed pics of the oil pump drive shaft. The drive gear for the shaft, that meshes with the cam gear, any chance the drive gear on the pump shaft is loose?

What weight oil are you using?

Something is rotten. Oiling system is pretty cut and dry. But, has to have all elements in play. Really sounds like something basic, like the pressure relief valve, or system clogged somewhere.

You should NOT have to fill the oil filter, when you install it. It is mounted directly on the pump, and if the pump gets oil, the filter fills itself, before the oil goes to the rest of the motor.

Last evil thought. When you lose oil pressure, pull the dip stick, does the oil look okay? Or, is it aerated? If air is mixing with oil, oil pressure won't read right, if at all.
 
No leaks. The shaft and gear are tight. I use 15/40. My neighbor and I looked at the prv and it looked good. The spring was in one piece. I bought a new pump and will install that as soon as I get time. I also have the car up on jack stands ready to pull the oil pan if needed. I dropped the steering linkage so I can get the pan off. I guess if the new pump doesn't work the next thing to do is drop the pan and check the pick up tube. Any tips on removing the pan would be appreciated. Thanks
