Fluid leak near the rear main seal - Fixed

[HCGxKaLiBeR]

So I was under the car doing some inspections I noticed fluids accumulating at the bottom of the transmission. Feel and looks like engine oil.

I wiped it off then then the next day it becomes visible again. It is not major as it's been a few days and have not noticed anything on the garage floor yet.

Seems to be coming from up top on the driver side. But oddly I'm also seeing some sort of crack in the middle.
Is this normal? Can't tell if it is a crack or just metal imperfection on the housing...

EDIT 6/22/26

Got the Bronco back. Took the dealer two weeks to fix.

Lifted the entire cab, replaced with an updated rear main seal retaining plate, replaced cylinder head gasket and tons of other gaskets. Replaced transmission fuild and engine oil.

Whew, luckily its all covered under warranty. It would suck pretty bad if not. It's only 33k miles.

I will post tech note pictures below.

Rear main leak is somewhat common on 2.7/3.0, so probably that.

The other thing just looks like a typically casting imperfection, not a crack.

I guess I will take it to the dealer and have them check it out.
Luckly I'm still under the 5 year drivetrain warranty + Ford extended warranty..

I checked it a bit more. Looks like it is from the rear driver side valve cover area.

I managed to find a photo of 2.7L ecoboost. Leak is from this area.

The technical term for this repair, I believe, is called “firing the parts cannon”

lol I would agree. But fixed is fixed (or at least hopefully)

I hope so. I crawed underneath again just to make sure things are done proper.

No visible leaks that I can see so far.

However... they forgot to tighten the stabilizer bar bolts My hope that this is fixed for good is not high. I only see what I can see. Who knows what else are missed.

Googled torque spec, should be 66lb ft. Going to do this one myself.
