oil breathers on ecotec?

[vx6]

where do oil breather go on the ecotec motor?

unfortunatly the PCV valve is inside the intake manifold so you can't get to it unless you split the manifold and you can't plumb into it either. the other breather comes from the intake manifold in the valley somewhere and goes to the TB. most people put a catch can in this line to stop the oil getting into the TB

You could block the one in the intake manifold and to the TB, then plumb your own into the tappet covers. Remember, an open breather system might not be legal where you are.

i wouldn't go that far. i'd block the factory PVC valve and then fit the catch can into the TB breather with a PCV valve somewhere in the line. that way you still have a closed breathing system and the added benefit of not having any oil recirculating through the intake.

i have done this on the VN (slightly different setup) and works well
