    Hello everyone

    I have a 2003 w900 with cat c15 6nz. I just broke down on the side of the road. Before I pulled over I noticed smoke when I looked at my rear view mirror. Once I opened my hood I seen allot of oil on the passenger side of the engine. Also my exhaust was blown white smoke and my blowby tube was looking heavy white smoke. I engine has about 300k miles after overhaul and was done by kenworth dealer. I dont know if it is a oil cooler problem. I have no idea

    Looks like its blowing out from the dipstick. Something's making excess crankcase pressure.

    No dripping out of the blowby.
    Drove on it 70mph. To get to a truck stop
    I don’t know if my engine went out or something.

    Spray all that oil off with brake clean or wipe it clean with 40 rags and fire it up to see where exactly it's coming from.

    Could be simple or could be serious.

    If you leave your exhaust off the turbo and the oil fill cap off when you fire it up it will help narrow things down a bit.
