I have a 05 brute force that I just bought about a month ago with some engine work done to it.  I mainly trail ride and go through the occassional mud  hole.  Recently I noticed that it seems engine is leaking oil from somewhere.  After looking into the problem I found that the oil is coming from the breather hose that connects from the cam covers up to the air box.  When I pulled out by air filter it was soaked in oil, any idea what may be causing this?  The bike idles and runs fine at higher and lower rpms.  I checked the hose for kinks and did not find any.

What they basically are saying is. If the oil level is at the top of the dip stick and you ride wheelies ore up steep terain alot the oil will puke into the air box through the crank case vent tube. This is where your oil is coming from like SWBF said just fill it to the half way mark on the dip stick and it will help. Also keep a check on the oil level from this also. This caused me some problems from not checking it so often between oil changes.

yeah, guys got it right, too much oil and too many wheelies will get the oil to flow back from the breather in to the airbox

Alright that makes sense.  The oil level is ok, but the wheelie level lately has been a little high.[:D]

Is there a way to install some sort of an oil catch can?

Most of us with BBK's use a YFZ catch can. You need to install another vent/drain back fitting on the rear head. I would not install the fitting with the head on the engine,to much of a chance of getting debis in the engine.

does the bike have high compression pistons in it and a danyatech as well?? if so you have oil blowing up that vent into the air box. pm me for more info mine and a couple of guys i know have had the same problem...

just reroute the crankcase vent line. cost about 15$ to do and very easy and lets you get more oil in crankcase instead of running half dipstick.
