Bearing clearances and oil pump selection with correct spring! Clearances affect oil pressure! Main, Rods, and Cam bearings are crucial for correct oil pressure! 2.0-2.2 mains, 2.2-2.4 rods, AND check the side clearances on the rods! Good Luck!
Oil filter bypass isn't going to change a thing. Even if it was stuck open it would only bypass the filter. It has no effect on oil pressure. The pressure relief in the oil pump could certainly have an effect but it wouldn't increase with RPM if that was stuck open.
Or that secret 1/2 oil plug might be missing?? If you look down oil send hole u should see it down there , Put a thin wire down there should go down about 10 inches or so, if it goes past the oil filter housing its missing.
Just wondering is the pickup tube tight how about the torque on the oil pump bolts I would think you double checked the rod and main clearences right?...
I have a 383 stroker in a 34 Ford that started doing the same thing change the oil and went to a heavier weight worked a little better but still not where it should be. Check the oil pump. Everything looks good don’t know what to do next.
Man I went to 15/40 oil and its up to 25 psi hot idling I'm not happy with it some guys tell me they are running 20/50 oil and happy mine is a 1 price rear seal block and from what I've read they don't hold as much oil pressure as the old blocks do
Have you tried switching gauges.i noticed the oil pressure was rising when you reved it.. if it was i could not see it..I would try strait 40 or vr50 weight. Just some thoughts
man from the research ive done the 1 peice rear seal blocks have larger oil galleys so at idle chevy said they didnt need but 15 psi so with that ive been running it and no issues
I made a comment about the distributor, but took it down.. I was thinking they going to think I’m crazy lol.. the second part of my comment with clearances go to a little heavier weight oil and last thing I mentioned was a leaking rear cam bearings.. I hope you find it.. it looked like you got up to 25 though
i tried to find the rest bof your message and couldnt iguess they will think 2 of us are crazy im going from 10/30 to 15/40 and see what that does the distributor swap did pick it up around 5 psi

Distributor depth can decrease oil pressure.Because the galley will be open also
Try the primer again. See if it’s same or better. Maybe try adding a quart of oil. Did you check pickup to pan clearance?
the pickup to pan clearance is 1/2 inch
I heard it ok to run around 7psi for every 1000 rpm.

Put in a stiffer oil pressure relief valve Spring.

all the clearances were 3 to 3,5 thou oilpickup is 1/2 off the pan and welded

Good video. Hope you find the issue!!
Have you tried switching gauges.i noticed the oil pressure was rising when you reved it.. if it was i could not see it..I would try strait 40 or vr50 weight. Just some thoughts
i did replace the gauge and they both read the same im going to check the bypass tomorrow and then maybe try 15/
trying some 15/40 instead of 10/30
Man, I hope it’s just the oil bypass sticking .
Maybe try another gauge before tearing into it just to make sure if not yeah try checking the bypass.
chevy i replaced the gauge they both read the same so the bypass is next
@@oldmanintheshopbuiltnotbou8726 👍
You have internal problems, the idle was terrible. Check the timing, did you degree the cam? Pull the pan and check the bearings.
Joe the motor is fine I did pull the pan and all clearances were 2 thou. To 3 thou
So did you ever get it was it the bearings? Let me no good video
2 years later so what was it???
man from the research ive done the 1 peice rear seal blocks have larger oil galleys so at idle chevy said they didnt need but 15 psi so with that ive been running it and no issues
Maybe the bypass is stuck
im going to try that tomorrow russell
Howdy everyone 😀 😄
hey guys

How about the o ring on the oil pump pickup tube?
this setup doesnt have a o ring in the pickup
That gauge sure seams lazy maybe try another one
that is the second gauge
I got no answers hopefully the bypass fixes it old man
lenxy i sure hoping it does
Use a heavier weight oil
Nobody wants to hear, cam bearings not tight enough.
15/40gives it 25 psi hot I'm not happy with it but it's doable
