Engine problems

I have a 2006 3500 g56 HO dually completely stock with 180k and its been having a few problems. It loses about 4 quarts every thousand miles. Its not coming out of the exhaust but from the crankcase vent tube and underneath the truck is covered in oil. It smokes a good amount while idling from under the truck and will drip a little. Its always towing around 19-20k lbs and avgs about 10mpg which is great concidering the load and has no power loss. The oil pressure gauge is always about 15% higher the the middle mark. Any ideas?
BTW I checked blowby and it will not blow the oil cap off just dance.

examine the crankcase gases filter in the top of the valve cover and it's oil return line for plugging, replace and see if the oil/crankcase gases spray out goes away.

if not:
take it to a diesel truck shop that specializes in Cummins and have a manometer test ran for excessive blowby.

the oil fill cap upside down tells nothing, at idle CC pressure is always low.

manometer test is performed on warm engine at rpm, not idle.

pull the injectors and have tested at an injector shop that is certified by Bosch for HPCR injector testing.

don't drive it.

I ordered the part and will install over the weekend. I thought the injectors going bad would raise the oil level?

leaking dribbling injectors will kill a cyl often before they start leaking to the point of extra diesel leaking on by the rings and filling the CC.

sounds like yours would throw out any diesel drainage into the crankcase before any increase in CC level.

get the injectors tested.

4 qts every 1000k, if the blowby filter and tubes aren't plugged?, you're looking at an engine rebuild

I lose a little oil every 1000 miles or so too. Not 4 quarts. More like 1 or 2. Depends on what I am doing. I worry about injectors and am in process of having them all checked out. I've read many threads on here about losing oil and injector problems, but never have seen this valve cover/filter. I clicked the link you posted stealhead, what do I need to check/replace on an 05? I do not drive it right now because, I have already gone down the rebuild road. Any advise would be much appreciated. Thanks. Sorry OP for using your thread.

where is your oil going?
being burned and going out the exhaust pipe?
out the blowby tube, dripping and being blown on the bottom of the truck?

these blowby filters very seldom plug and need replacing, their primary purpose is to catch the oil mist in any blowby gases, filter and collect it for drainage back to the crankcase instead of being blown out the blowby gases tube.

get a manometer test ran on your engine.

pull and have the injectors tested.

It appears to be coming out of the tube. Until I drained and replaced my tranny fluid I thought I had a leak there(no dip on the G56 and all fluid was accounted for) Then I see oil on this blow by tube and start checking on the forum again. I think it is worth the $60 to replace the filter. I never had a puddle under the truck. Oil under truck I am hoping this is it. I will also be getting injectors pulled and checked plus manometered. Thanks again for your help. And thanks to OP for starting this thread. Blow by = bad news. I'm not excited about the testing. Can bad injectors cause blow by?

manometer test tells all.

no need for injector test unless you have symtoms of leaking failing injectors.

low rail pressure.

high return rate

engine miss, rough running.

diesel halo around oil spot on white paper.

lab oil analyis showing more than 2% diesel fuel contamination in oil.

rising oil level in CC.

Cummins specs 1 qt oil per 1000 miles usage as normal for the 5.9. 2 qts start of a problem somewhere.

leaking nozzles with poor spray patterns cause hot spots in combustion chamber i.e. piston, aluminum alloy melts, leaves pulled melted aluminum on cyl walls causing extra friction and finally stuck piston. then the real horror happens stuck piston =s broken rod out the side of the block.
extra diesel washes oil off cyl walls and rings, extra wear and breakage of rings.

yea mine runs/idles perfect except that the tach says its idling at 200rpm half the time itll pull up a 7% grade with 4 cars on it at about 40mph all day while my f450 is stuck at 30 lol. Its been like this for about 12k miles and I use it for my business so thats about 5 weeks of driving. I bought it for 11k so I guess I deserve to have to do some work to it. Whenever I check the oil I have to check like 4 times because its hard to get a good reading on it. It almost seems like its trying to get rid of excess oil after being overfilled.
Also I figured with what I tow the egt should be very high and if there was uneven injector spray it def would have melted something
