02 7.3 small oil leak

i've got a small oil leak on my 02 7.3..its only got 73k on it! alittle bummed about that..just wondering where the most common place is? rear main? oil filter bracket?

i havent had time to check it out yet but just from glancing under the truck it looks like its coming from between the oil pan and tranny pan dripping off this little tin piece under the bell housing?i will get a closer look when i get a chance..

thanks..

check the valley, i bet its either a hpop line, turbo pedestal orings, or ebpv rod, otherwise your sol lol, rear mains RARELY ever go out on these things.. nearly unheard of.

I have what looks like a similar leak. Upgrading the turbo this weekend so going to get a good look at the pedestal and surrounding bits and see if replacing the orings helps.

Lakailimited06, I've got the same issue on my 2002 F350 that I just bought. I'm new to the diesel world as I just bought my first truck ever, with the 7.3L. It has a small oil drip from the transmission inspection plate, and looks like the oil is coming from up top somewhere. I'm going to follow your thread and hope it leads me to finding my leak. Thanks for posting this up.

I've got the same leak, also. When I pulled into my shop after work tonight, I saw a puddle of oil on the floor that wasn't there the day before. There is oil sitting on top of the engine and running down the back of the block. This truck is an early '99 work truck and even though I've owned it since new, I'm not that familiar with repair procedures on it because I've never had to do anything to it. It has 325,000 kms. on it and I've never had the turbo off. I can fix this myself but any advice would be appreciated.

Angry o-rings on turbo

Well, I replaced my turbo o-rings last week. It's a lot of work for a 55 year old guy. You younger guys can handle it better.

Mine still leaks, but now it comes down from the top left side instead of the top right side. So I created another leak while trying to fix another. The top of the engine is dry and the oil is coming down the rear of the block on the bottom, then drips off the transmission inspection cover, like all you other guys.

I probably screwed up the new o-rings would be my guess. So evreyone BE CAREFUL when replacing the turbo on top of the pedestal. It's heavy and difficult to get back in place on top of the pedestal without screwing up the new o-rings.

Good luck to you all. I'm probably going to have to call a stealer and get hosed.

my leak actually looks like it is coming from the oil filter bracket..anyone ever hear of this? im sure its possible maybe just not that common..its hard to tell but from the filter bracket and below it looks the most wet...im going to have to clean everything and start fresh..the top of the motor doesnt look too bad, or bad enough to spot a leak anyway..

You really need to get in there with a good light and mirror if you have one, my money is on the turbo pedestal OR EBV rod on the pedestal. Remove the plastic cover, (2 13mm bolts) and get up/on there and go a-searchin. Bet you'll find it in the valley, somewhere. The drain for the valley is right above where you "see" the leak.
