Not the 3.5L 603 though, IIRC it was a 90x?

Did some quick research, this link shows a 603.972 in the 350GD

It's driving pretty good as I am breaking it in and have added one and a half quart of oil going on 3000 miles at which time I will change oil at 3000 miles, I guess. I used the cheapest oil I could find (name brand), Havoline at Sam's and STP at Dollar General and some left over Delo I had all mixed up, but mostly 10-40. My car took 10 quarts of oil on initial start up.

Anyway, going from one quart in 200 miles to two quarts in 3000 miles and possibly more and the add oil light hasn't come on yet is fantastic.

Car has used 4.5 quarts of oil and that was to 9,000 miles at which time I changed the oil and used Rotella regular 15-40 diesel rated oil. The last 1,000 miles to reach 10,000 miles, the oil is basically holding steady and I haven't added any oil and it stills registers basically full at the top of the oil dip stick. The big bolt above the water pump leaks a little and account for some of the small usage. The car runs better and better every day up until today. I don't know what it will do tormorrow, but it seems to make a sweet screaming sound when I step on it a little. Except for some on start up, the blue oil smoke is gone as noticed when driving behind the car. It's the other issues that have been getting me lately. The door locks went out, the A/C went out, glow plug lights came on. Cruise control kicks in when it gets ready. But as long as I can continue to forget how much oil I have used and have to go back to the books to add it up, the car is fine with me. I used to know that when I drove 200 miles, I was one quart low, which was very easy to keep track of and was fresh on my memory every day I drove the car. I'll know more at my next oil change in 5,000 to 6,500 miles. Now, I just need to figure out how to get some of my money back from having mastered this car as of today and am still working on solving a few other experiments to better understand this beast of a car, the 140 diesel.

BenzDiesel, I couldn't find the post where you said what exactly you did to fix your engine. Did you repalce the rods? Pistons? Bend them straight? Re-sleeve? What improved the oil consumption to ~2000 miles per quart?

Car is running better and performing better than it has since I've owned it. There is leakage at that big nut above the water pump and I have to add some oil, but NOTHING in comparison to 200 miles per quart. I have cured the excessive blue smoke problem and the car now smokes black when the turbo kicks in, which is no problem, since I know the solution. I have ongoing experimentations with the car in my efforts to extract maximum performance from the car. It is a shame that Americans never got to know how these cars are REALLY supposed to perform, in terms of efficiency to operate and dependability and reliability worthy of a diesel powered car costing over $70,000.00 new in 1993. Anyway, patience and determination is the key to ownership, along with proper financing. Otherwise, the W140-OM603 is NOT for the faint at heart.
