Thread: 5.0 L oil leak question

Pull the heads and see if you can determine where the leakage is occuring. There should be some signs there to see.

Are your head studs the proper diameter for the holes in the heads? I would start, before you pull the heads by identifying which holes are the drain back holes (usually in the bottom of the head, for obvious reasons. then when you pull the heads look at the mating surfaces on the head gaskets in that area.

Make sure they put the gaskets on the right way. Ford gaskets are easy to put on backwards, although this usually affects the cooling holes the most.

I really hate dealing with an engine someone else put together, as you indicate yours is. I would suspect whoever put the heads on didn't torque them right, or somehow screwed up the gasket, or it's orientation.

You may want to pull the engine down and check to see what else they may have done wrong. All it wil cost you is a new set of gaskets and some time.

Then you will know where you stand.
