Hi Groovygal, wow you're quick! Good for you on the small engines! Maybe its just me but I found Grooving a lot easier with a vice to hold the TB or carb being grooved. I bought a Panavice model 301 from
they are here in Reno NV. You are off to a super start, my congrats to ya!
Ok on your Focus... I dont have any info here on the PCV setup for that car. I would first try searching the Net to look for info/pics.. try Google-ing 2010 Ford Focus PCV location. OK I just tried that on the first page of search results I found links to a few focus forums where people were asking same question. I tried to paste in the link but it came up here as lines of code! Just Google-search that and look through the results. I did read folks talking that it's easier to see/access from underneath the car. Look under exhaust manifold driver side for starters.
Once ya find the critter follow the hose on PCV valve to how/where it connects to intake manifold downstream from throttle body--that will be a connection to manifold vacuum. Idea is to leave PCV valve intact If the PCV Valve itself is connected to the Crankcase. One end of PCV will always be into man. vac other into crankcase. A PCV Valve can potentially be on either end of the hose. We just want to cap off the Manifold Vacuum port the PCV hose connects to and move the open end of PCV hose to tee in to the breather hose.
Breather hose will go from downstream of air filter to crankcase, most often to the valve cover. If you find and identify these hoses/connections you can realize they form an air flow path. Fresh filtered air enters between air filt. and TB, goes into crankcase. This fresh air mixes w/ blowby and crankcase fumes. It's then drawn through PCV valve and into intake manifold to be burned w/ air/fuel charge in cylinders.
Whole "curcuit" is "powered" by MANIFOLD VACUUM, and this acts as a big Vacuum Leak reducing manifold vacuum level. Any reduction in Man. Vac hurts the Groove effect and MPG! So we just allow crankcase gases to enter engine BEFORE TB, to be burned as before. As airflow increases w/ more throttle opening there is a slight pressure drop (vacuum) in the air intake duct. This along w/ slight crankcase pressurization from blowby ensures these gases will travel this revised path into engine. But this way we conserve vital Manifold Vacuum.
Groovygal, have a good look around the site for more about PCV Re-routing. There is another thread on this page with good pics of how another Gadgetman re-worked the PCV hose, I cant remember the name its late here! Just look around here you will find it.
PLease keep asking questions you are doing GREAT!!
