What's up? My cousin just got an 04 f350 with the 6.0. He has an oil leak and took it to a mechanic (not a diesel mechanic) and he said it was the rear main seal. I don't know much about the 6.0, but am leery about the analysis knowing these fords can leak from hpop or some where up top and leak down. Is it common for the rear main to leak on these?

Thanks

John

 

John,
Look in the 6.0 Tech folder for "How to fix 6.0 Leaks". The 6.0 rarely leaks from the rear main.

To properly diagnose the source of the leak is to add die to the engine, run it and look for the source with a black light.

Good Luck...

 

If I recall correctly it is almost never the RMS. tell the mech to look again, or take it a mech that KNOWS the 6.0. not just a mech that knows diesels

 

Thanks guys, I figured it was probably some thing else. I'll look it over a bit next time I see him. Or at least get a diesel mechanic haha.

 

How bad is the leak?????

lots of these have a bellhousing drip that just hangs there.

My truck was making oil getting alittle high leval. drippen off the bell housing seeping from bedplate. once I fixed the making oil issue and kept the truck at the right leval everything dryed up and went away.

Im not saying that he is making oil just the oil leval alittle high will have issues

And theres a few things that could leak Oil uptop and will show an oil leak right where your buddys does

Start looking clear uptop at the Oil Filter housing and work your way back

how bad is it leaking

 

It leaks bad enough to leave a 3 inch spot on he driveway. He just got the truck 3 weeks ago and I see him often since he mows my neighbors yard but I haven't popped the hood since he told me it was leaking. I did see the spots where he parked though haha.

He took the truck to a guy that is a good mechanic just not a diesel mechanic, If I had a British car that's who i'd see so he must know oil leaks lol.
