Oil breather/catch tanks

[berg]

Just after opinions on the best way to set one of these up on the GTE engine

 

After having all my turbo pipes off again i noticed the oil residue inside all of them (which i know is normal) i guess as the engines get older and the mileage goes up this inevitably gets worse

 

I'm thinking about adding a breather system (BPU on stock twins)

 

Ive seen just the exhaust side ran to a breather tank with intake side still connected to manifold, And I've seen the usual setups on single turbo cars where both valve covers run to the breather tank

 

Whats the best way to do it on these engines?

 

Also for running both to the breather tank, is it just a case of blocking off the existing ports on the intake manifold and the turbo pipe or is there more involved?

IMO the best way is to delete and block the low throttle/load side of the PCV system (the one connected to the plenum by a one way valve, link the two cam cover breathers together, run this to a catch can, preferably baffled (filled with stainless scourers to hep oil drop out, and run the outlet to the turbo intake, this will still use the high load side of the PCV system and aid ring seal etc, and still get rid of most of the oil residue.
