Just changed oil ( 40wt delo) 1200 mile trip, checked oil level and looks like 1-2 gallons over full. Slobber tubes are not connected to pan. Only possibility is fuel oil, but from where? 4106 / 8v71 Thanks for any info. Jon | ||

Sounds like you have a cracked or loose injector line. | ||

Cracked or loose jumper, bad injector, fuel pump seal leaking? Anyone done any headwork on your engine recently? I would not operate the engine untill diagnosis and repairs are completed. You may be able to pull the valve covers and look for a "clean" place in the jumper area...or you may see a fuel leak. Is the engine missing? Loosing power? Could indicate an injector failure.

Jon - Get a paper towel and lay it on the ground. Now insert the dipstick fully, and pull it out, allowing one or two drops of oil to land directly on the paper towel. Watch the oil spread on the towel - if you get a fast-spreading circle, you've got diesel in the oil, and you need to find the source. JR mentioned a few places to look - which will require you pulling the valve covers. A cracked or loose jumper will show up quickly upon inspection, usually. For confirmation, get an oil sample kit from DD or other sources, if you don't feel comfortable with the paper towel test. HTH. . . | ||

JR is right, especially about NOT operating the engine until repairs are made, AND the oil and filter changed! Fuel "oil" is NOT a lubricant!! Doing the math, it sounds like your lube oil is at least 25% diluted with fuel, which will cause bearing damage quickly | ||

The oil needs to be changed. The rocker cover need to be removed to look for a loose connection or cracked line. If possible, disconnect the fuel line to the heads and pressure fuel lines with a small electric pump. The leak or fuel loss should be easy to find. Some times the leaking area is very clean.

When using a fuel pump to check for leaks, or prime the fuel system, use a low pressure pump. Too much fuel pressure will damage the fuel pump seal. Something designed for an automotive carburetor would be safe. Don't use automotive fuel injection pumps which may make upwards to 60 lbs of fuel pressure. Good luck, JR | ||

Pull the covers and run it. Greased Lightning makes clean up easy after you find the leak. |
