How to replace upper intake manifold gaskets | Ford Explorer and Ford Ranger Forums - Serious Explorations
I think this is your engine ??? If the upper intake was the one that was torn, then I would replace it, it's pretty easy to get to.
It's hard to tell where the fuel rail is in these photos, but if the new injectors are in, I suppose it doesn't really matter.
The lower intake gasket is more of a PIA to get too, but if that's OK, then no need to change it.
If it was leaking the truck would run like crap because there would be a vacuum and/or coolant leak.
From what I can see the upper gasket isn't paper like my 3 litre, yours is probably neoprene, some care needs to be taken so it "seats" properly.
Still can't imagine how someone can be so carless that this can be torn.
If it doesn't seat right, then there will be a vacuum leak.
I see the fuel rail now (or at least one side of it) it's covered in dirt and hard to see.
The fuel rail is usually just held in there was some small bolts, once those are removed, the rail is lifted out with the injectors as a complete assembly. No need to remove the lower intake, or least there shouldn't be a need too.
