All true, that is why I used Heater Hose because it is more rigid than regular rubber hose. I also made sure that no kinks were in the line running down to the new cannister and made sure to lock the hose down with a couple brackets along the way. I also made sure to route the exit hose from the cannister all the way out the back of the vehicle. I thought about welding a 3/4 bung to the end of my exhaust. That would probably pull the CCV vapor through the line and into the soot mix, but decided against the extra work. I would not tap into the exhaust before the muffler since there would be back pressure that would cause the CCV to add pressure to the already pressurized Crankcase. All in all it is a good mod. I have no oily residue in the charged air side and I removed my Intercooler and cleaned the existing oil residue from there. I don't know how much that bought me, but I know it is clean.
