how many miles are you driving a day? week? have you done an oil and filter change and seen if it still does? you may not be able to see the oil on the driveway, try laying down cardboard sheets... oil cant just dissapear, its gotta go somewhere...

 

You might also check your oil cap. I was losing oil like that when I first bought my Durango, and it turned out to be my oil cap (of course I figured that out last )...

Later...

Brekar...

 

This possiblility seems unlikely since you lose so much in such a short time, but...

You could have a blown intake gasket due to the plenum they used on the 5.x's. Take a look down into your throttle body and look for oil, it should be dry. The original plenums were aluminum, so they expand at a different rate than the metal surfaces they mate up against. This causes the intake gasket to separate. To see if you have the original plenum, take a long telescoping magnet and drop in down through your TB. If it sticks to the plenum, then it has been upgraded to an aftermarket metal plenum. If it doesnt, it original. Typically, this would cause you to lose about a quart or so between oil changes... could be more or less though, I suppose.

 

I drive roughly 60-70 mi a week.
My drive way is white... you can see a flea on it! lol
I just had the oil changed 2000k miles ago

 

I did a little research after my org post and one of my mechanic buddies said the same thing about the plenum gasket..
It calls for 5.5 labor hrs... ugh
So that means it will take me 14hrs a case of beer and possible trip to the emergency room (they know me well there!)
So I will take your advice and pull of the air intake and check the TB.
Thanks for the insight!

yup check the plenum gasket

also check for oil in the coolant (hopefully there wont be any, but you should check)

brekar, what was wrong with your oil cap that it was causing you to use oil??

 

+3 on the plenum gasket.

Welcome to the family......


Anyway, it really doesn't take that long. I had my 5.9L (which is the same as your basically) down to the block in 2 hours, yes that was removing the heads as well. If I recall, you don't even need to remove the injectors or fuel rail, hell not even the Throttle Body for that matter. You simply remove the wiring harness and clip it up out of the way, remove the fuel line at the coupler (you use a special tool but you can get around it) and remove the intake. Don't remember if you have to remove the valve covers or not, but I think I would.

The thing is, when you install it you need to be VERY careful not to slide it around after you put it down. Use some dowels as a pilot to line the holes up. And remember to put RTV in all of the 4 corners where the new gaskets are touching each other because the are 4.

 

if you plan to keep your D dont just replace the gasket, replace the pan aswell with a one fix step....

thanks for the hughes engine link.. (very useful info)
Their gasket is $100 more than O'reilly.. hmm
It does have alot of positive reviews, so I guess I will bite the bullet.
If you guy's have any interest I will keep ya'll posted.
I'm thinking about hooking up my buddies G-Tech to it so I can get a before and after result.
