Ther only real problem with breathers is the smell you get sometimes after a high boost run pushing any type of pressure into the crankcase will cause fumes to be noticed.
If you engine is so tight you have zero blow by then you are lucky I guess. Not saying it doesn't work because it will under ideal conditions.
A large oil seperator before your turbo inlet would stop it from sucking oil into your intake tract but the exhaust would really be the best bet for evac.
Has anyone noticed any smoke from the tailpipe with an exhaust evac type of set up?

 

the smell is from a wounded motor. i had breathers on my 6.0 and i smelled the fumes. put them on my 408 no trace of fumes, havethem on abuddys 6.0 no fumes at all, have them on a ls1 no issues. my 6.0 had issues thus smell and consumption of oil

 

That's what I never understood. Why the breather? Why do you want to allow air into the engine? Why not both lines (or one, like thunder550) into the catch can and then the intake, so that only blowby fumes enter the intake? As long as there is minimal blowby, the crankcase will be in a mild vacuum. During WOT with leaky rings, all of the blowby would be burnt in the engine. Wouldn't it?

 

On my personal truck I run 3 3/8 hoses off the valve covers to a catch can/breather setup infront of my inlet air filter.This way the inlet sucks in the fumes.From my years of FI experience ,ni PCV is good no matter what you do.Just run a breather setup.

Now my secret is out.

 

you not allowing in as much as you are letting air out of motor. pcv is a pollution way of dumping the air back into the motor to be burned which is done by vaccum so if you have any issues with the motor it will suck the problem into the motor. if you have oil issues, the oil in the combustion chamber can cause denotation and we all knwo what denoation causes.

or you can go hardcore and use the vaccum setup off the headers but thsi is for race and not street.

 

The last time I tried to run a breather in the oil cap it got saturated with oil pretty quickly. Was I doing it the wrong way?

 

Mine is definetly hurt.

 

Don't forget about the part where it caught on fire and almost burned your truck down,
