6.4L bed plate leak - upgraded gasket kit?

[Delta Jim]

I just had a 6.4L bed plate leak fixed at the dealership. Took the truck in for a leaking rear pinion seal and asked them to check the oil leak at the motor/trans bell housing. After inspection, they stated it was the bed plate leaking and fixed both issues under warranty (truck at 42k miles). Service advisor said the bed plate leak issue is common.

My question is do the dealerships use an upgraded gasket kit or a different application process? Or are they just replacing the original gaskets? (there is a whole page of seals and gaskets on my warranty receipt) If it's just the same gasket kit that is already known to fail, what would prevent this leak from occurring again in another 40k miles? Cost to Ford was $3500 for both repairs.

Truck is a weekend snow & tow vehicle and not a DD so I will hit the 5 year warranty expiration before hitting 100k miles. I don't want to personally fund this repair in the future. Anybody know the details on if or how the Ford dealership repair solves the issue?

TTT... hoping a forum Ford mechanic could offer some insight...

There is no "gasket". There is a rubber oring style seal that fits in a groove in the bedplate. I know myself, and the rest of the techs in the dealership I work at install it with a skim of ford grey RTV silicone on it before assembling. Have not had one come back leaking. This is the same method used on the 6.0L bedplates.

Thanks WildStyle... appreciate the explanation and insight into additional measures you take to keep the leak from returning. Next time I'm near the dealership, I will ask if their diesel techs are doing the same or just replacing the OEM o-ring.

Had to get towed to dealer. Computer shut down due to a short. They claim they found a short in the brake control module. But we will see. I also said something about the dripping oil. It's not bad and I expected them to not do anything with it since they all and they said they are dropping the tranny to replace a seal? Is this the bed plate?

[WildStyle]

Bed plate requires the cab lifted and engine to be put on a stand and rotated upside down.

Oh well then I'm not sure what they are fixin

Sounds like they are replacing the rear main seal.
