I have a 2001 Ford E350 van. My "Service Engine Soon" light came on as I was noticing some power loss and engine roughness. I pulled off the freeway within 3 to 5 minutes to find the remaining oil pooling underneath. the entire underside and back side of the van was coated. After getting the repair which included:
Oil pan Gasket - E350 Super Duty, Gas, V10 F7UZ 6710 AA
Thermostat - E350 Super Duty Diesel
Main Bearing Oil Seal/Rear Engine Cover plate -E 350 Super Duty Diesel - Rear F4TZ 6701 A
Then, of course Oil & Filter
After driving it home after the repair I noticed that at near 50 to 55 MPH there is a little subtle roughness that I'm not accustomed to. I also noticed that same subtle roughness the day BEFORE these seals went out. Maybe I'm just paranoid but is there something I should know about before I go on a long trip tomorrow?

If your rings are worn, the exess blowby could have blown out the rear main seal and caused other leaks. 2001-what's your mileage? Have you got an airfilter that works? Any induction leaks? What's your compression like? Are you using oil?
WARNING: A worn diesel will run on sump fume blowby with increased power until the sump is dry-wrecking the engine. There are 2 easy ways to stop a motor in this mode- 1 throw the decompressor, or 2 seal the air intake until it stops-do NOT use your hand!!! NO, I wouldn't drive it anywhere until I knew much more about what's going on. And the mechanic is a fool for not suggesting these scenarios, as they're well known to all competent diesel mechanics.

how low was the oil level in the pan?what it MAY be is you filled the high pressure oil system with air.these engines need a minimum of 500PSI of oil pressure to fire the injectors.the pressure will reach 3000 PSI at wide oppen throttle.now if you got air in this system it will take about a day of driving to get all the air out and get it back to running normal.

No, but I want to become a diesel mechanic. I have a nice touch though.

did your mechanic ck the rod and main bearings 4 damage when replacing r/main seal ? after that much oil loss, damage could have accured to the bottom end causing vibration or roughness. cause could have been oil pump relief spring sticking.was the oil pump replaced?

It is possible that engine blowby caused the seals to blow out and it may repeat itself in short order. Have the compression and blowby checked.

Is it still leaking oil?
