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.  |

Okay, I just used a brand new gauge with 0-15 PSI scale to measure bypass pressure with air using a leak down tester.
Bypass starts to open: 6 PSI but flow is just seeping through Bypass fully open: 10 PSI with significant flow These values are very similar to the values I calculated using kitchen scales so I have a high confidence that the values are ballpark within say plus or minus 1 PSI.  |
