I have the FSWerks CAI enroute to my house to install on my 05 focus. I currently have just a simple breather filter on my valve cover where the EGR hose was attached, however the filter shows obvious signs of oil leakage. Is this normal? I read in a post about the PCV delete that an EGR re route has been done with just a hose to route the EGR down to the road surface. I also have tossed around the idea of just capping the EGR off. Any advice and insight i could get would be great. What are the differences between running the hose down and out of the engine bay compared to a Breather Filter? or would it be more to my benefit to just run the hose back into the intake? Also what effects could I expect if I were to just cap it off until I could get the EGR De-activated?
