Hi I have a early 99 7.3, I have parked it for the winter an I had moved the truck the other day an have noticed it had leaked some oil, after looking for the source I found that it is leaking out of the #7 cylinder exhaust port. I know the oil is forsure in the manifolds usually burns off but now that it is not getting to operating temp it is staying a liquid. Where is this oil coming from?!!
Thanks

 

It's probably the valve cover gasket.

 

Not the vcg replaced that because that was my first thought, it's definitely coming from the manifold

 

possibly the seal on the exhaust valve stem? but that shouldn't produce that much oil.

 

you sure it's not the turbo pedestal O-rings?
