I'm not sure about out in Calgary... but this mod would be considered illegal in Ontario :roll: :roll: :roll:
The PCV is considered part of the emissions controll I beleive
This modification is illegal in the US as well. Modifying the factory emission control system is a big no no in the states. Also, in IMO, this is not a good modification to make to a street driven vehicle.
Did you gut the PCV valve, or are the internals still there?
Personally, I do not like venting the PCV to atmosphere.
Here's why:
1) At idle, vapors venting in engine bay have a distinct odor, which can make their way into the passenger compartment.
2) Having the PCV routed correctly, just after the TB allows a vaccuum to occur within the cylinder head, which helps remove the blow by gases and helps with piston ring sealing at idle.
3) If the PCV valve is just left on the head, with the internals intact, it could impede the ability for the head to ventilate the blow by gases, therefore causing problems down the road, such as other seals leaking, etc.
If your concern is only with the oil vapors re-entering the intake track and gumming up crap, then you should install a catch can IMO. This will allow you to collect the oil vapors there, but still retain the proper function of the factory PCV system.
