I had to maintain some semblance of idle, otherwise the video is moot. Nonetheless, that's a cold start.
Mine pretty much sits at 70 psi as I warm it up. At the track fully warm, it's close to if not 80 as I go through the traps, but the oil is at full temperature. Your video looks like it wants to go much higher when cold. Do you have an adjustable regulator?
No, but it might be going higher than that cold. Hard to say from the video. There is a big difference between cold oil and hot oil as far as how much stress there is on parts.
I have whatever the TA cover came with. This is after driving for a while, at idle. Seems a bit high to me.
Back the adjuster out. There may be too much preload on the relief valve. That won't affect the idle pressure, just limit the maximum pressure. To get the oil to the highest temperatures requires 15-20 minutes of highway driving.
I had to remove the 60 lb spring the ta pump comes with and install a 40 lber to get the pressure to where I wanted
I just read a thread about distributor gear issues and realized I never updated this one. Dan Zepnick was kind enough to send me a few larger (diameter) roll pins that required widening the hole in the shaft & gear to install. It worked like a charm and took quite a few good thrashings after my wheelhop issue was resolved.
I had a 455 shear the distributor roll pin . I replaced it . Then it was putting out too much pressure and ballooned the oilfilter and pushed the element out and clogged the pick up . Thus starving the motor of oil .
Many years ago I sheared one on a really cold morning. I had a HV oil pump and it would sometimes hit 100 psi when cold out. This particular morning I had to jazz the throttle to keep it running bc the choke had been acting funny. Saw 100 on the gauge followed quickly by zero and silence. Unfortunately I did not have an adjustable regulator
