help!, my exhaust manifold won\'t fit!

I'm in the process of putting my engine back together since I replaced my headgaskets. I tried to put the 2 exhaust manifolds back on and the passenger side bolts don't line up. However the driver side fit perfectly without any problems. I stuck the very rear bolt in and hand tightened it and then tried to get the very front bolt in and the hole was about an 1/8 inch off, as if the manifold shrunk or something. I know I had considerable trouble removing the AIR hose (it's fuel injected, 88') from the manifold and had to use a pipe wrench to get it off. Is it possible that I bent the manifold in doing so? And what can I do to make it fit once again other than buying a new manifold?

did you take them off when they were kinda hot still? they could have shrunk. i doubt it you bent them they are kinda thick. if you buy new get headers. [img]/forums/images/graemlins/angryfire.gif[/img]

4 options:
1st, scrap it and buy headers [img]/forums/images/graemlins/cool.gif[/img]
2nd, loosen them all up and try to put all the bolts in and THEN tighten them down.
3rd, heat the manifold up and install it again.
4th, see the 1st option.

I've seen this before. The guy used a spreader to get them to fit back on the heads. He borrowed it from a local shop that rebuilt motors and such.

I've got one of those. Picked it up at Car Quest. I had the same problem with both of mine. Just call around and ask for a exhaust manifold spreader. [img]/forums/images/graemlins/usaflag.gif[/img] [img]/forums/images/graemlins/k5.gif[/img]

No, I doubt it was very hot when I took it off. It had been sitting for about a day since it last ran. And yes, headers are definitely on the "To Do" list but for now the funds are low. I plan on putting eddelbrock TES headers. Anyway, can you rent these "exhaust manifold spreaders" at autozone or oreilly or carquest? If not, how much are they to buy? thanks guys.

That is a very common problem. Those log style manifolds almost always warp like that. It does not matter if they are hot or cold when you take them off. They make a spreader to get them back on, as noted above.

Re: help!, my exhaust manifold won\'t fit!

Or you can make your own with two bolts and a one of those long threaded nuts. Bolt center ports onto head, insert spreader between rear port and middle ports, lengthen spreader until holes line up and insert bolts (then repeat for the front). This process works, but using commercially made spreaders is easier, as they "Grip" the manifold better. Using bolts can be tough to keep from slipping on the manifold surface.
