Low Idle Oil Pressure, Wanting to find out how easy it is to install Tangerine's oil pressure relief kit Options

[Highland]

The engine is a fresh rebuilt 2056 stock D-jet engine running Brad Penn 10W40. Once the oil gets warm the idiot light comes on and the oil pressure gauge (electrical VDO) goes to almost nothing.

Thinking about trying Tangerine's Oil pressure relief valve:

Is it pretty easy to install with the engine in the car? Does it slide in easily or does it need to be pressed into the bore?

The description says it bypasses the oil cooler so is the oil always going through the oil cooler even on cold start?

One more note. I misplaced the engine's original plunger and spring assembly so I bought a used one. I have since found the original spring and plunger. Just wondering if anyone thinks putting the original part back in will fix the problem. The original engine was built as a 1.7 and I don't recall it having this problem.

Yes, new bearings all around and the crank was measured for matching bearings. The rods are new H-beam and I plasti-gauged all of them at 0.0015".

During break-in I used a mechanical gauge and after the break-in run the engine settled at 1200 rpm 40 psi (mechanical gauge) with 30W break-in oil. I used a thermocouple to measure the oil on the dipstick at 125F.

I will try the 20W-50 and reinstall the original oil relief assembly at the same time.

I'm surprised I'm not getting more encouragement to use the Tangerine product. Does anyone know if it's pretty easy to install or is it difficult to press in upside down from under the engine?
