What is this? Filter? Restrictor? Whats it there for?

And the first pic is for water in water out?

And the black one oil in and below it oil out?

[Simon-S14]

its a oil filter, and its on the water fitting. Oil is the top one

It's pretty special....

There's no in or out for water on a core, but the out should be rotated slightly higher for thermosiphoning to take place as per garrett recommendation.

[Adz2332]

Thanks! We couldnt work out why it was on a water one

The oil only drips through it, doesn't get pumped in there like some people think, you can always tell the bottom oil drain as its the only major difference between all the other fittings, so the top one is oil in (opposite to oil drain) then yeah water return is supposed to sit slightly higher than water in.

What? Are you serious?

It is pumped through it. How else would the oil get there? Ball bearing turbos need less flow than bush bearings, but certainly way more than being dripped on....

There's a guideline on how much flow, and I can't remember it, it its not measures in drips!

The smaller oil inlet then outlet is only to stop the oil building up pressure in the core. There should be a flow of oil but having the return bigger then the inlet should ensure that the flow is never restricted causing pressure.

Maybe I wasn't clear with what I meant to say - It doesn't flow through it at 50psi "as some ill experienced people have thought. Of corse it has a flow rate or how else would it move through the turbo?

But thanks for the serious reply.

[Simon-S14]

pressure is the opposite to flow, by having the restrictor in place you reduce the flow to the required amount but the pressure goes up,

[89CAL]

Pressure is indirectly proportional to flow

To the OP, I'm guessing you were talking about the cylinder shaped object between the oil inlet and the line? It looks like it might contain a mesh filter to me, but the easiest thing to do would be to pull it off the other fitting and have a look. If it has a mesh filter inside it should come apart for cleaning. If its a one way/check valve (and I'm not real sure why you would put one there) then you can test that by blowing through both ends.

If its a restrictor, and it seems WAY over the top for that, you should be able to blow through it but feel quite alot of restriction. In my head theres no way its a restrictor, there are much more discreet/compact ways to do this
