I just took my first 1,000 mile trip to North Dakota where it is ten below weather conditions with my 2001 4x4 psd after a complete engine swap. It used two gallons of oil, I don't know what to do. Here is the link to the thread of my engine build. http://www.thedieselstop.com/forums/f24/almost-completed-engine-swap-couple-questions-213793/
I replaced the injector o-rings with complete kits from Napa on the initial rebuild. I took time installing the o-rings and the injectors. I don't think that they are leaking, but not going to rule it out. Are the Napa o-rings junk? There are no visual leaks under the truck. It has great power with no chip installed. Starts great, doesn't miss at all. No known issues other than the massive oil consumption. The engine I installed was in good condition out of a 1996 psd. It had crosshatches in the cylinder walls. I didn't notice any unusual engine blow by with the oil cap off with the engine running. Any body have any ideas before I have to drive back to Texas? Any ideas or information on what to check or repair will help out. I brought tools with me just in case and have a warm and clean shop to work out of.

other than external leaks I would drive it the trip back and that would be a good break in and see how it along the trip to be safe

I have a couple short 100 mile trips up here before I head back to Texas. I will keep an eye on the oil level and hope it doesn't get any worse. I didn't check the oil on the way here, I drove straight threw without stopping, 18 hr drive. I don't know when it started using oil. I hoping it was an average over the 1000 miles.

with it running loosen the oil filler and see if the cap blows off engine as this would indicate blowby and you would see smoke blowing out
if injector o ring was pinched there would be oil in fuel filter and you would be consuming engine oil

Blow the oil cap off after you loosen it a little? Is it normal to have some blowby? I'll check the fuel bowl for oil.

If you overfilled the oil when you installed it (difference in late vs early PSD dipsticks?) then it might use oil more rapidly. Mine will sometimes drop a quart fairly quickly after an oil change if I fill right to the top of the hatch area, and then it will pretty much stay there till the next oil change 5000 miles later.

I'd just keep an eye on it on that long trip. It's probably going to use a little more oil when it's been hot for a long time versus shorter trips.

I ment that it should not blow off. If it does that is bad.
I would get it some time to break in and just keep the oil level up

Have you looked inside the turbo outlet. I have truck here thats loosing about a gallon every 1,000mi. from a leaking turbo.

It was the injector o-rings torn. Replaced all eight with good quality ones form Ford. Back on the road again.

The Napa o rings torn??
Do you think it happend on the install?

Sounds like it was easy to fix...

The Napa o-rings are JUNK! The quality of the Ford o-rings over the Napa o-rings is hands down the best out there. The Napa o-rings are made of light weight o-ring material that was very easy to install over the injectors and very easy to tear during installation. The Ford o-rings are very stiff and very hard to install over the injectors. Once installed the Ford o-rings become part of each injector, where the Napa o-rings are loose and sloppy on the injector. Ford o-ring kits will triple the cost of the repair. But anybody would agree that is better to do the job only once.
