fuel/oil drip from vent hose

[ouraydog]

We have a 2009 WinnebagoTour (Cummins 400hp) and today after a short drive of 75 miles I noticed something that looks like fuel drips on the rear flap and on the front of our truck. Closer inspections showed that the drips were coming from a rubber hose that hangs down beside the radiator (drivers side). I cannot see where the hose goes to after it passes by the intercooler pipe.

The hose is about 5/8" outside diameter and 3/8" inside diameter and made of black rubber. It looks like a vent hose of some sort, and with the engine running there was no air pulsing out of the hose.

Any ideas would be appreciated, normally there is not a drop of anything on the back of the coach. No recent service and the oil level is exactly at the full mark.

I have also post this on the Winnebago forum, but thought that you guys might know more about it.

Thanks, Bill Barton

Sounds like you've "found" the slobber tube. Google "slobber tube filter" here on iRV2 for a fix..........
