I have a 1998 ranger with somewhere around 200k miles and my exhaust manifold cracked. No big deal, huh? Well... I started looking and it appears that nobody makes them! I only saw one used one on eBay, and they wanted $200 shipping! My question is, where can I get one? I heard mention of the 93-97 ranger 2.3 engine will work, but can't even find that. What I did find is a Dorman 674-230 which is for a 1992 and older ranger 2.3 and 2.0. Will that one work for the 2.5?

When I swapped a '98 2.5 in to my '93 that had 2.3 I used the original 2.3 tubular style manifold with no issues.

sheltonfilms.. just went and looked at your post re exhaust manifolds.

I think the tubes welded to the flange help keep the flange straight as the bolt inside will act as a longer lever to prevent warping. Bolt captured will stay straight when temp changes, and the 'tube' will stay parallel to the bolt shank, and keep the flange evenly applied/torqued to the cylinder head. Well, it was a guess anyway.
Did you notice any difference with the tube manifold, compared to the cast?

I am pretty sure from readings that the manifolds should bolt up across all years. As I understand, the cylinder heads changed the valve stem diameter, and perhaps the diameter over time, but the casting remained the same. Same casting implies same outlet/exhaust port shape.

Will it work the other way? And how about the pre 93 manifold? Main thing I'm thinking is the egr port.
I don't think you need it to work the other way. You want to put a '93 manifold on a '98 2.5, right? That is exactly what I did. The only issue is that I don't think the tubular manifold has the provisions for the hoses that run to the DPFE.
I have no experience with '92 and older manifolds.

I just found a place I can get the original type one for $30. It's a guy who specializes in Ford rangers and has a ranger parts yard. Now to find time to go get it. :-D

It took me a while to find one. I found one about 45min away at a junkyard and when I got there it was the wrong year. The second one I found through an online junk yard and asked for pics before they shipped it.

Mine was rusted to hell and there was one bolt/stud that I could not get out of the head. Even with a torch and easy out I could not get it to budge. So I left it in and im just running with 7 bolts.

Recommendation. Chase all the threads with a tap before assembling. This includes in the head and the bolt holes for the cat. Use some anti-seize to reassemble. I also painted mine to help keep the rust down later.

Yeah, it took me a while too. But thankfully a friend told me about this local parts guy who specializes in rangers. I called him and he had one sitting on the shelf. I'm redoing the head, all new valves, lifters, springs, seals etc, and I'll be chasing all the threads.
