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.

I use the tangerine valve. easy to install, just as easy as the spring and piston.

what is good is that it rides in a smooth bore with a tight fitting piston that will seal against an o-ring.

Try the stock one and oil weight first. (its cheaper).
it is a good product otherwise also.
