yet another oil pressure thread Options

[jmargush]

74 with a 2056 1 ½ seasons on it.
CB injection
Running 20W 50 Joe Gibbs GP-1
Dakota digital head temp gauge
Dakota digital oil pressure gauge and sender
Also still running stock sender and light in gauge
Not sure what temp oil sender is in the engine but the gauge is the one with the small red section.

I had the light flickering after autocross runs last year so I put the Dakota digital gauge on to see what pressures actually are.

This has become a huge stressor as now I am not sure if I trust the gauge or if the engine has issues.
The pressure is good when I start but drops to below 6psi at idle once warm, yet the stock light doesn’t come on.

I took some numbers last night to track it.
74 degrees ambient
Start up pressure 50 psi

After driving about 4miles oil temp gauge had just moved off the zero mark (case measured 165 degrees with IR thermometer)
12.5psi @idle

Drove some more
Oil temp gauge over the T
28.5psi @2400rpm
Drove more
Oil temp gauge between E/M Head temp 317 degrees (case measured 225 with IR thermometer)
26.5psi @ 3000rpm

Let the car sit for about 2hrs
Oil temp between E/M Head temp 300 degrees
15psi @3000rpm

Drove further ambient now about 68 degrees
Oil temp gauge over the M Head temp 315 degrees
10—12psi @ 3000rpm

Once I parked it and measured the case with the IR thermometer I was getting 180 -190 degrees.

Is it possible to have air stuck in the line going to the sender? If so would it cause inaccurate readings?

Does it sound like Chris’s/ Tangerine racing oil relief fix would help this?
