No oil pressure in the 1st 8 seconds, How to get turn of the key oil pressure Options

[Vietnam6871]

Engine is brand new 2.3 liter stroker that runs great except no oil pressure in the first 8 seconds then it runs fine with 30 lbs at idle and 60 lbs at highway speeds. Temp runs at 180 degrees normally with 210 being the hottest on very hot days. Any ideas on why it takes 8 seconds? Validated on dashboard guages and a mechanical guage. I can't drive this until I get pressure with the turn of the key.

I see my mechanical gauge showing pressure right after the engine starts. 60 psi is great. I would attach a gauge at the engine and have someone start the car to see if you have instant pressure. If so you have a delay of oil pressure reaching the gauge.

Something about a mechanical gauge, I have one for sure. Cheap insurance

Agree with the sentiment/concern in some of the other questions, that something external like a cooler or filter could be causing drain-back when the engine isn't running.

This is worth validating - 8 seconds to generate oil pressure after startup is too long.

Do you have a high-mounted remote cooler or filter by chance? Gravity could be your enemy here.

Edit - you could check for presence of oil in any external oil circuit before startup by disconnecting oil lines.
