PCV crankcase, catch can installation...

[mars]

OK OK, I know I am the worlds greatest MS painter you've ever seen, but I am just wondering of this plumbing is correct...

Have a look, and leave a comment.




As of now, I have the PCV hooked to manifold, and a breather on the rear valve cover...

I NEED to eliminate the breather, the fine here for a breather is HUGE...

Thanks!

You do not want to remove the PCV from the intake manifold. You need that "strong" vacuum from the intake during idle and off boost times. For boost times (PCV closes) you want something in the intake track previous to the turbo to pull the crankcase gases in. Where you have it in your diagram is fine, but do not remove your PCV from the intake plenum.

is the pcv on the rear valve cover or the intake plenum?

The PCV runs from the rear valve cover to the intake plenum. 8)

On a 3400 the PCV is front side   8)

Thanks for the info.  I just thought for some reason it was possible to completly isolate the PCV blow by gunk from going into the intake, but I guess you can't do it that way.

Thanks!

You will have low vacuum (more like air moving) at all times at the turbo inlet stream...but it will not be as strong because it is not a part of the "vacuum circuit" post throttle body. 8)
