Rb25 Oil Filter Pressure Relief Valve Help

[thegame-01]

Hi SAU,

Did some research but don't have a solid answer and don't want to risk it.

Ill be running after mark oil cooler and removed the stock on of my RB25DET

Where does the oil filter pressure relief valve go? left hole or right hole and why (educate me please:)

Thanks in advanced

See attached pic.

An easy google image search would give you and answer as to which one. Logic should tell you that a fully machined lead in on the left side is where it goes.

Thanks Dobz for the logic

i need to do this too, but my block has a 'plug' of some sort in that hole. how do i remove it?

If it were me, I would drill and tap the plug, get a slide hammer screwed into the hole and try and slide hammer it out.

The fact that you are going to drill it means that swarf is going to be created, so you would want to give the oil ports a good clean out. It would be best done with the engine out of the car and the block stripped

FYI, I run a thermostatic oil cooler plate and still have the plug installed with no issues at all. I think you can buy an oil filter that has an internal bypass to get around the problem of not having a physical bypass in the block but I havent looked into that fully yet
