BIZARRE Problem With A 2003 Cummins Ram. #1688564 10/21/14 02:55 PM 10/21/14 02:55 PM

This truck has been ridden hard and probably has 150-200,000 miles on it. He has (according to him) recently developed an issue. He says that he can fill the crankcase with oil, drive 10 miles, and the crankcase will be empty. In addition, there is diesel getting into the oil. If he pulls the oil fill cap off the valve cover and puts his hand over the hole with the engine running, his hand will be wet with diesel and the dipstick has diesel on it. It sounds to me like (this being Costa Rica) the diesel tank at the gas station may have had gasoline in it, he ran it, and totally destroyed his pistons and valves causing uncontrolled oil burning which is sucking the diesel into the crankcase through the head. Any thoughts? 1970 Dodge Charger R/T Hemi Orange U-code 4-speed 1971 Jaguar E-Type Series 3 V-12 4-speed 2+2 Signal Red.

One more thing, there is a fair amount of positive pressure in the crankcase. He can feel it blowing air out of the oil fill. I'm wondering if it isn't a combination of bad rings and a stuck injector. 1970 Dodge Charger R/T Hemi Orange U-code 4-speed 1971 Jaguar E-Type Series 3 V-12 4-speed 2+2 Signal Red.

If they can't see where a trail of 4 gallons of oil in 10 minutes is coming out of that thing, then they shouldn't be behind the wheel. At any rate it sounds like a wiped cylinder.

Quote: 12 or more qts of oil in 10 miles with no leaks ? and that thing would be smoking like a freight train Sure kind of throws a wrench in my theory. I've got 232K on mine, oil gets changed every 8K or so. Being that it is 12+ qts I have never pulled the dipstick to check it. It doesn't smoke and it doesn't leak so I figured it would never be low. May have to rethink that one after reading this... ...FAFO...

I remember the 2.2 tubo cars would blow the turbo seal and use oil like crazy but they would also smoke out the shop when you pulled it in the shop. Ron

Then I don't believe that all the oil is gone at 10 miles. Actually they will run on gasoline but really really badly. On rare occasions when they had a new operator at fuel fill on the assembly line they would put in 8 gallons of gasoline in a diesel truck and it would get started on it at the Huntsville test (electrical test). They rattled really loud but ran. They shut them off fairly quickly, 30 seconds to a minute run time. They were then were pushed off the end of the line to repair. The fuel tank was drained, then replaced and then they filled with diesel fuel and were restarted and the Huntsville test was run. The engineers said the short run on gasoline didn't hurt them. Eventually they set up the fuel fill system to eliminate the chance of that happening by having to scan the truck being fuel filled. It wouldn't allow you to pump the wrong fuel into a truck after it was scanned. It would shut down the line if you did try which required a restart by the section line supervisor. If it was run on 87 octane gasoline for any real length of time it would be really bad. Kayse can't keep up at all now. lol

Not saying it hasn't but it is not as common for sure. The piston has a lot more "meat" around the bowl area on a 305 hp. Usually if it has burned a piston it will pulse the blowby out of the oil cap with the engine running and have a miss. You will also hear uneven cranking of the engine when trying to start the truck. The source of the fuel leak still needs to be addressed first.If you are the adventurous type, You can remove the valvecover with the engine idling to look for a fuel injector leaking into the crankcase. If no fuel leak is found initially, you may have to ramp up the fuel pressure to find the leak. This can be done by disconnecting the Fuel control actuator plug on the high pressure pump. Unplug the FCA with the engine off. By doing this the fuel pressure will be at max operating levels and the leak will be very easy to spot. Look for it to steam or fog fuel around the bad injector. Before restarting the engine with the FCA unplugged, Be sure to stand back away from the engine as it can be messy and dangerous. Have someone in the truck that can shut the engine off quickly if needed. Disclaimer: BE VERY careful if you attempt to do this. The fuel will be under extreme pressure and can hurt or even kill you if you are too close. 392 gen III hemi on E-85 727 trans Dana 60 10.02@134

I basically repeated all of the advice here to him and he says he'll let me know when he finds something out. 1970 Dodge Charger R/T Hemi Orange U-code 4-speed 1971 Jaguar E-Type Series 3 V-12 4-speed 2+2 Signal Red.
