Have been reading the breather posts with interest, especially if they are similar to the type sold for Sierra Cosworths etc.

Reason been when I had My Cossie I copied (fabricated) a virtual replica of the swirl pot design and heavy oil droplet design basically a pipe from the cam cover breaths through a seperator whilst heavy oil droplets collect on a splash plate and fumes/pressure released to atmosphere via a filter, oil collected is piped back to the sump. If this is the same idea I will make a test one up and try it,any views anyone. Jeff TT

As I see it, the solution you're talking about is

similar to the oil catch can design I heard about.

 

The kit in the group buy puts the crank case uder slight vacuum instead.

This will suck the oil out of the turbos, or makes it wanna

go to the sump rather than through the turbo seals.

 

This made me look at the stock setup.

At idle, the air is sucked in through the PCVs to the inlet manifold.

Fresh air enters through the hoses at the front of the intake cam covers.

There is a restrictor in those hoses which will cause a slight vacuum to build up in the crank case.

Maybe making those restrictors smaller would have the same effect as the above-mentioned kit?

On the other hand, at boost, the air will travel in the opposite direction and then you don't want small restrictors there.

 

As my turbos are fresh, I'm more interested in getting rid

of the problem with sucking in oil to the intake manifold.

This happends at a hard right turn.
