PCV Hose advice needed

[Nick OTeen]

I'm in the final stage of getting the 7 registered. The CARB (California Air Resources Board) wants me to route a hose from the back of the Zetec engine's valve cover (where the little K&N filter/breather now sits) over to somewhere on the intake side of the engine so that I have a closed loop.

 

The referee said it must be before the throttle plate and suggested routing it into the air filter somehow. However, that would put it before the air mass sensor's hot wire and I fear the oil vapor would could the wire. He also cautioned against routing it into the rubber "elbow" between the air mass sensor and the throttle as he feared the elbow would crack - this despite the fact I've got the parts and expertise to reliably place a fitting there.

 

I've been to the local Ford dealer and got some advice based on the stock Zetec SVT motor setup. Anyone out there with a Zetec-engined 7 that has such a hose in place?

 

Thanks

I know this sounds kind of bad but..... just do it in a way that is easiest to revert back to what you currently have... this car will never see another smog ref once approved. It only has to drive to the smog station and back home in that condition.

 

Too be honest, I have that set up (hose to tube extension that the air filter attaches to) and have no problems in 4 years. I have a breather on the rear valve cover area though. No real good pic. Oh, it's a honda but exact same issue.

Install an oil catch can (oil/air separator). Most vent to the atmosphere, as does the one on my Vauxhaul powered Westfield since it does not have to pass emissions. It is easy to convert it to a closed system - just remove the breather filter and run a line to your air filter, then put a hose fitting on the top flat part of your filter. No oil will be in the line so you don't have to worry about the gooey mess. Just drain the catch can once in a while.

I put a catch can on mine just for good practice, no emissions or inspections here in Florida. As Canadian 7 stated, its easy to drain the catch can every once in a while and it does serve the purpose. I have a sintered bronze filter on the top of mine but if I wanted a complete closed loop, I would just remove the filter and install a plug.
