Rb25/30 Rb30det Vvt Internal Oil Control

[cdorhout]

Wow, that's great. I thought about the same theory when I did my RB30, but I didn't dare pull that plug out for fear I'd never be able to find something to go back in there. Very good idea!!

anybody else doing this mod?

im going to give it ago just wondering if there are any others out there who went with this method.

[fletch rb30]

mate of mine did it and has been running for maybe a year with no problems

I did it after reading this post. Worked great! Plus, I got rid of my oil leak from the external oil fitting in the head. I had the hole in the head welded shut.

[SS#eater]

awesome, going to go with this method. you would be crazy to go external if this is so simple.

hi just wondering what the bung does you circled in blue in the last pic?and what you did with it.also do you have to make an oil return for this vvt setup? cheers

[psi]

The blue circle is the oil return port for the VVT.

The oil comes into there from the VVT valve and this port allows the oil to return to the head and drain away.

does that clear that up for you?

I pulled it out just to see what was in there! There is nothing that I can see in there that would/could be of any other use!

(but I did have to check! hahaahaa) Anyway, DONT pull it out unless you need to.. and I cant see why you would need to..

[psi]

yea mate.. That explains it very well!

Now you have seen it... how easy is that to do?

Cheers for the pic, I didn't think to do the pic like that..!

Good one.

If you click on my pics of the plugs, its easy to see where I drilled the holes.

Now with the new pics above ^^, that should remove all guess work of how it works.

cheers

[daisu]

Just to get an idea of how it works, is this what is happening with the oil feed?

Thanks for the Pm Aaron, after reading it then finding the above pic, confussion all sorted

Going to pull the plug out tommorow nite

[psi]

Feel free to take more pics and post them up..

I tried to give as much info as I could, so, you should be able to do the job without too much bother.

be kind to the plug when removing it.. you dont want to break it in half! or drill too deep!

happy modding mate!

[works 510]

Damn that plug is in there tight!

Well its out and getting the drill treatment tommorow

Cant belive how straight forward it is

[TriniGT]

I have a Neo engine and I am not seeing the plug you'll have I am only seeing what looks to be a metal slug and a welsh plug not sure if it is the same thing. Any ideas?

Read the WHOLE thread again! check out post #4.

I put some colour on the bit that you need to look at!

[JVDSKYRINE]

Hey i was wondering if you still need an upgraded oil restrictor after this mod?

[TiTAN]

this mod has nothing at all to do with restricting oil flow to the head, it is changing where the oil goes once it is in the head.

Damn what was I looking at??? But in the pic you can see that mine has some sort of ballbearing on the outside, is the plug behind that? Would I need to drill into the ball and then somehow get something screwed in and pulled out and then tackle the plug?

[psi]

I han't done a Neo head.. but I'm guessing that Nissan didn't stray too far from what they already know works.

Please take another pic, up close and front on, just like mine so everybody can see what your looking at.

[bigturbo]

hey just one more thing on this does it actually work because on the factory 25 block the vvt is getting a direct high pressure feed straight from the oil pump wheres this method is only getting in from the head?also when you other guys are putting the pistons in the block do you put oil on the rings or assemble dry 2 prevent the bores glazing up cheers chris nz
