Check it yorself by blowing compressed air into the cam oil feed and seeing where it comes out, assuming that you have the head off. That way you will k ow for sure.
That's an excellent product. An ecu con trolling the pump is only guessing the fuel flow needed, by actually monitoring return flow the control would be way safer.
There's heaps of info on it. Even detailed guides.
My advice is therfore search for that.
It's not hard, for me, but if you are a complete beginner it's heaps hard it's all difficult.
And it will cost more than you think.
I'm reasonable sure the front cam bearing is fed via the vct oil supply, so blocking off the vct oil supply causes it to run dry I could be wrong of course!
Don't do it man.
Can't find it can't fix it. You will probably snap it off or cross thread it It something even more mental than that.
What do you plan on doing to the cas?
How come you don't Google image search rb25 cas. It's not hidden.
But DONT DO IT. TAKE IT SOMEWHERE.
Oh just remembered, on th pre neo head you can drill out a brass plug in the front of the head near the inlet cam gear. That might be what the guy did before you?
You need to run an external oil feed to the head as the vct oil feed is on top of a coolant gallery on the rb30 block.
Vct is WAY better than being able to dial in the inlet cam.
