Oil Levels

I recently took my 1999 F350 (36,000miles) to the dealership for an oil leak at the turbo. It has a 7.3L diesel. I was informed that the leak my have been caused by overfilling the engine. The service manager stated that when the oil level is between the operating level marks that the engine oil level is overfull. He stated that the level should be at the bottom of the hash marks just at the add oil level. When I asked if there was a tech bulletin or service notice from Ford for this recommendation he was unable to provided any and stated that the dipstick marks were mismarked on this model and year of engine, but Ford never issued any tech info on it. I have been measuring out and using the exact amount of oil required as stated in the owners manual and never encountered this problem before. Any knowledge or comments regarding this? Is there a Ford factory web site to send this inquiry to?

I would complain to the manager or even higher up than that. I always run my truck at the full mark and zero leaks. This guy is making it up as he goes IMO. Get his statement in writing make copies and send them to Ford for confirmation.

Sounds like the Christmas turkey I had in the oven last year; half-baked & full of *****! Top of the hash mark is full. Bottom of hash mark means you'd better add a couple quarts NOW! The problem caused by overfilling is splash & aeriation in the pan. If it's full enough, the splash can be forced out the rear main seal. Since the turbo is at the top of the engine, it's not susceptible to splash.

Bunch of crap. I just finished changing mine 2 hours ago. Poured in 15 quarts (just like Ford says, just as I always do) and it brought it up to the full mark like always. The service managers at some shops don't know their tail from a hole in the ground. That is a stange way to try to stop an oil leak, run it low.
