6.7L Oil usage rate,fuel vent line.

[Eagle6.7L]

I had posted this topic I guess in the wrong section by mistake,well I got 66 hits on the question,of usage rate on 6.7L's does anyone have any info on this,not that I am using oil,but was curious as to what it is compared to my 07 5.9L.And also if anyone knows of this any info on this matter is that,I just noticed that under the fuel tank filler neck,next to the fuel vent device,I see some small amount of sepage running down the fuel line to the tank.

NORMAL OIL CONSUMPTION: Below are industry standards for normal engine oil consumption: Mileage below 50,000: Normal oil consumption is one quart for each 1,000 miles driven. Mileage above 50,000: Normal oil consumption is one quart for each 750 miles driven. TEST TO DETERMINE ENGINE OIL CONSUMPTION: Operate engine to normal operating temperature. Fill engine oil precisely to FULL mark on dip stick gauge. Use paint pen to mark the engine oil drain plug to prevent tampering. Check engine oil level after 1.000 miles driven. Refer to normal engine oil consumption listed above. POSSIBLE CAUSES FOR EXCESSIVE ENGINE OIL CONSUMPTION: PCV OR CCV SYSTEM: Check the crankcase ventilation system for proper operation. Oil may accumulate in the throttle body or intake manifold. Also, rocker arm lubrication oil flow returns to oil pan through drainback holes in top of cylinder head. Plugged or restricted oil drainback holes may contribute to excessive oil in crankcase ventilation system. SPARK PLUGS: Examine all spark plugs to identify the affected cylinder(s). Spark plug on the affected cylinder(s) will usually be fouled or wet with engine oil. VALVE GUIDES AND VALVE STEM SEALS: Inspect valve guides on the affected cylinder(s). Replace valve stem seals on the affected cylinder(s). PISTON RINGS: Check piston rings on the affected cylinder(s). Piston rings may be too tight / worn / broken / carbon build up in the oil control ring. CYLINDER WALL: Examine the cylinder wall on the affected cylinder(s). Cylinder wall may be severely scuffed. Perform hone procedure on the cylinder wall or replace cylinder block / short engine assembly as required.

Thanks Bob,Was this posting of yours from the Owners,Service,or TSB,SB from RAM.And does anyone have a idea on the fuel seepage coming from the fuel tank vent tied to the fuel hose up by the filler neck.

Examine spark plugs? On a diesel?

Sure, How do you think they get it to start? They are right next to the muffler bearing. But not the Flux drive conduit.
Lol

This is a long standing statement from Corporate and is still used on both gas and diesel applications

The fuel you see is from filling the tank too full. There is a small canister vent filter zip tied to the fill pipe that overflow fuel comes out of and runs down the vent /fill tube. Seen it a few times on a few trucks, including mine.

View attachment 95240This picture was when I found the seepage,since then it has become wet with fuel and dripping down on to the fender lip.Kirwin,I thought this to be true as well.When you trace the line back it goes horizontial across to the tank.If this is the case then fuel is making it's way horizontally and then vertically it goes up about 12 inch or more then vents out of the small canister and on to the fill hose for the tank.I believe this might be a safety issue,because no fuel what's so ever should be venting out on to the diesel fill hose and comtaminating the fill hose.I think fuel is making it's way up the tank vent hose and spraying out of the vent canistar,before the nozzel shuts-off.You say you have seen this on others as well.Your post shows a 2013 RAM 3500,is this happening as well on yours.Also all my fills our by pump shut off's, no top off's...Bob 4x4 this as well a interesting quote,meaning I would be surprised if RAM/Cummin's would agree to this type of usage rate for gas/and diesel applications. Sag2 might be able to shedd some light on this subject.

21,000 miles. Hasn't used a drop of oil

Well I can tell you it happened to me when I filled the truck at a fuel station at an significant angle that resulted in overflow out of the vent. I did add a little after the pump clicked ff but nothing substantial. I agree the line goes horizontal but fuel is not stationary in the tank and moves around quite a bit as the truck moves around. Also, when fueling, diesel is full of foam that restrictis and percolates thought the vent although you can't tell it on the new capless system.
