Manifold leak/crack
Is it a really tough job to get the passenger side exh. manifold off on 97 4.6 4WD? It is leaking from the front cylinder, toward the front of the vehicle. I cant tell if the manifold is cracked, or if it is just leaking from a busted gasket. I can access it from the wheelwell, but I guess I am worried about snapping off a stud or something. As I am looking at the manifold from the passenger side wheelwell, is there supposed to be a bolt or stud to the right(front) of the first cylinder outlet? There is nnot one, but I am used to looking at 60's and 70's ford manifolds with two bolt holes on either side of each cylinder. HELP!!!

The passenger side is a piece of cake to remove compared to the driver's side. Yes, there should be 2 studs per exhaust port. Studs snapping off is a common problem. Since you're missing one in the problem area, then it needs to be repaired in order to get the manifold to seal up again, even with a new gasket.

I replaced my passenger side manifolsd a few years ago. I used plenty of penatrating oil and gave it time to soak in. Removing the studs in the block is pretty easy, I thought the studs that connect the exhaust system were more difficult. I ended up cutting them off and buying new studs for the collector. When you do the job I found it best to remove the inner fender well to provide extra access. Good luck.

I just did my passenger side a few months back, it really was much easier than I expected. I would say 2-3 tops. Definitely buy a set of bolt extractors (auto stores sell an Irwin Set for less than $25). I got the studs from Rock Auto for under $10 and you can even get the gaskets there for under $10. Don't forget to order new flange bolts and nuts since it is just easier to just cut them or burn them off to pull the manifold out.
I asked my local Ford Dealership what they get for this fix and they said at least $1000 till they see how many studs are busted. I did the whole job for less than $30 and it wasn't bad at all. I had 3 studs broken toward the rear.
Good Luck!

So, i have not actually inspected the expy yet, but from what ya'll are describing this sounds like an issue i am having. If a broken stud is the case, does the whole manifold have to come out to remove the broken stud and gaskets be replaced or??

Yes, it's the only way that you're going to be able to get a grip on the old stud to turn it out.
