I didn't do the re-route, but that sounds normal. those are the blow by and crankcase fumes coming outta there. Hope it's nothing serious. Should mostly just smell of oil though..

its pretty normal , dont worry about it. the gas smell is more than likely gas vapors venting out of the gas vent hose. or do you mean the burnt or unburned hydocarbon smell (like an old car exhaust smell) then it is just crankcase vapor checkout the huge Breather reroute thread and the other threads on it.

Well now you are more open and breathing and running harder. I use synthetic to reduce the smell and the oil burning.
