Do you drive the truck like you stole it? If you have a boost gauge what PSI are you running at? With the amount of oil you are talking about it sounds like you have a valve or ring issue or have a heavy FOOT

 

Naw man, can't afford to drive it that way. Got it to haul my racecar with. Don't have a boost gage. I don't know how the previous owner, the original owner, drove it but it has low miles. Just rolled over to 117,000. Runs great, just a little rough at start-up and then smooths out.

 

I think I saw a post on here that Fleetguard makes a breather assembly that separates the oil from the vapour and returns it to the crankcase. Do a search and you might find it. It's kind of a band-aid solution, but it might get you by for a while and it's easier than a new motor.

 

Only one I found only went to 2002 and mounted on the front of the motor and didn't look right. Couldn't find an application for a 2004 5.9. If you see it let me know. I'm still looking.

 

well, mine is doing the same oil out the blowby, rough idle, back pressure in crankcase, (take off oil filler cap and feel the backpressure), but runs fine, no power loss, a little white smoke at start up, and blows a little more black smoke when on it, evry one is telling me i have a hole ina piston, or bad rings on a piston

 

You have a bad injector. Which one, I don't know. You can burn a piston up if you continue to drive it like this.

 

How do you check the injectors? Can't afford to put it in the shop.

 

so just a bad injector can cause the crankcase blowback, god I hope that is all it is

 

Well, I'm having the same issue with my truck and it's a 05 with only 70000 miles on it now(that's when the problem started).

I'm using about 3 quarts of oil every 1000 miles and Dodge says yes, there's something wrong, but no, we can't do anything until it gets worse. Has good power, runs fine, rough idle on start up and blows way more smoke than it used to, but supposedly all wtihin acceptable limits.

I think the next thing you have to do is do a compression test, and whether you find anything or not, your next step is going to tear it down and have a look.

OR, you could just runit until it breaks??? I've put about 7000 miles on mine like this and it still runs good.

Just my opinion on the very limited knowledge I have, take it for whatever it's worth. Here is link to my thread, hope this helps.

Oh, by the way, dealer believes it to be a ring issue, broken possibly?

 

My 3500 was manufacturer in 1-04. Is it a 2004 or a 2004.5? Want to get the right injectors.

 

i wonder if you could take the plastic valve cover cover off and put some extra breathers in the actual valve cover like they do on the first and 2nd gens?

 

That depends. Look at the valve cover and make sure. I am fairly certain your engine will have an 03 mfg. date on it.

January is the month of the Gray area...LOL. Mine was built Jan of 04 but has the 305/555 motor built in Oct of 03. There are no 305/555 - 04.5's if that the engine you have.

 

Mine smells like a Fork Lift running on LPG.

If the engine is internally pressurized (excessive air coming out the oil fill cap or breathers) I would suspect bad rings or a bad gasket. What would a bad intake gasket do? Something is pushing compressed air into the block. Even the turbo could do it. Breathers are meant to allow the piston movement to suck and blow a little bit as they move in and out of cylinders. Remember one is going up as one comes down, so they cancel each other out quite a bit.

Something is very wrong, and the air flow is taking oil mist out with it.
