    Have a 97 w909 with a n14 celect 525hp. Last night temp dropped down to 26 degreesF where I unloaded. This morning I noticed oily slob at exhaust stack. My water temp did come down to 125. Anyone have any similar issues? Truck ran great.

    Need to high idle it. If coolant got that low then it doesnt get hot enough to burn fuel correctly which can cause issues internally. If it still slobbers try turning on the fan to put a bit of a load on it or getting a bra for the truck.

    Probably sooty fuel if it sat at low idle all night. I'd bump it up to 1200 if it was just going to sit running all night.

    Unburnt fuel mixed with soot from water temp being low and low rpm

    Most trucks you can just turn on the cruise and hit the resume button, that'll usually send the idle to 900 or 1,000 rpm.
