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.

Can I insert just a couple basic questions here?

- If you're removing the oil filter and replacing it with a sandwich plate...why would oil go through the bypass, given same psi on both sides of the ball with, as noted, a larger surface area on its back side; and

- Even if it does go through the bypass, whether fully or even slightly, why do you care? You could remove the checkball and spring entirely and the oil is still flowing from the inlet to the outlet.

And...discuss.

EDIT: Here's where you shold be focusing your energies:

Because it’s not the same PSI on both sides. That’s the issue here. The pressure difference between the upstream side of the valve and downstream side increases because of all the backpressure in the hoses, remote filter mount, cooler and fittings that are now positioned between the upstream and downstream sides of the valve.

- Even if it does go through the bypass, whether fully or even slightly, why do you care? You could remove the checkball and spring entirely and the oil is still flowing from the inlet to the outlet.

Because bypassing the valve bypasses the remote filter and the oil cooler. I don’t want it doing that when cooling is needed. I installed a remote cooler so it would cool the oil, not bypass.

And...discuss.

Haven’t looked at these yet.
