Good question, I don't know.

 

Well, I got the rig back this evening after being in the shop 11 days. They replaced the bed plate seal, also looks like they replaced the rear main seal again too. It was 20-ish hours worth of labor; 6 to remove and replace the cab, almost an hour-and-a-half to mount it to the engine stand, 12 hours for the repair itself and other bits and pieces.

I'm going to try to drive it a lot over the next few weeks to see if the leak comes back.

Felt weird driving her again after driving the F150 they gave me as a loaner.

On the plus side, the dealer did a full detail on the truck, even treated the leather. Too bad it's going to rain tonight!

 

Thats what I was thinking, Did you find out if it was Diesels?
Would be worth knowing

 

No idea, didn't think about it when I dropped it off or picked it up, was just glad to have it back in the driveway.
