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.  |

I don’t want to answer for OP but my understanding is he is worried about bypassing his external oil cooler and overheating. Operating oil pressure hasn’t been part of this conversation.
I view this discussion as largely theoretical. Unless the external oil cooler and plumbing is stupid restrictive the bypass in the oil filter console is a non issue. On the other hand, if you do have a HIGHLY restrictive external cooler and hose assembly, the last thing in the world that you ought to be doing is plugging or increasing the relief pressure of the oil filter console bypass. That situation of high external oil cooler restriction, is basically the same limitation of oil flow as a plugged & restricted oil filter. This can cause bearing damage due to loss of pressure and flow at the bearings. Which of course, is why the automotive engineers that designed the system put the oil console relief valve in there in the first place (ie to ensure oil gets to the bearings). This is why I initially suggested that the oiling diagram be looked at closely. |

But if you're that worried about it then stop using those cheesy cheap-ass sandwich adapters and use one of Chris' good bespoke ones: https://tangerineracing.com/shop/ols/produc...-oil-cooler-kit |
