Bypass Valve on Stock Oil Filter Console, Looking for relief pressure of bypass valve to help with design of remote oil filter and cooler Options

[Mr Beckstar]

Hi all.

I have a 4 cylinder 2 litre and am adding a remote oil filter and oil cooler circuit via a spin on adaptor attached to the stock oil filter console mount. But I noticed the oil filter bypass valve in the stock oil filter mount (circled in photo below) and now I’m concerned that, at high rpm, I’ll be bypassing the remote cooler/filter circuit. Does anyone know the bypass valve relief pressure setting? Knowing that would at least allow me to judge whether it’s an issue.

Where in the world did you come up with 3 psi?

I appreciate the idea that you’re going to try to measure the pressure drop across the filter but I’d seriously suggest you look into the accuracy of the gauges you’re using to do the measurements. If you’re using conventional dash mounted pressure gauges, the measurement will be lost in the noise and inaccuracy of the gauges. As a mechanical engineer, I will tell you that if I were trying to do what you’re proposing, it would be done on the bench and the test would be done on the filter console only without bringing an bunch of other variables into the test.

If you’re that worried about bypassing the external cooler, you should be using a full flow cooler and should not be using a spin on adapter.
