Need some advice for an IHC Engine

I have an old IHC 304 that I was taking the exhaust manifolds off of last night. As I separated the manifold from the engine one of the lobes where the studs attach broke in half. Leaving me with a problem of reattaching them. Has anyone ever run into this? Could I weld a stud into the casting lobe? and Am I screwed?

Thanks in advance

you can weld cast iron, but not easy, lot's of articles on that on the forum.

You could use a big washer and hope you have enough overlap and you can tighten it enough not to leak.

OR, you can find a new manifold, the 304 manifolds are not that hard to find.

 

it's actually the lobe on the head that busted.

 

pic?

 

Well...if you can weld or braze it yourself, I'd try....beyond that, unless the head is in excellent shape, or newly rebuilt, I'd try to find a replacement as the cost for a welder to do it may exceed the price of another head. IH heads, most of them, anyway, are dirt cheap. I can suggest some sources, but the shipping would sting a bit as the closest I know of is in Springfield, Ohio. You can usually find IH parts locally if you dig a bit. You might even check a local Navistar IH dealer as the 304 & 345 engines were used for a long time.

Is the engine still in the chassis?

 

Yeah the entire chassis is stripped and is in the process of slowly being reassembled. Then I hit this snag. I'll take a look around locally for used 304 heads. Thanks or the Navistar tip. As for pics I did not snap one off, the only thing I snapped off is that lobe.

Thanks

 

The 304 uses a head with smaller ports than the 345.The smaller 266 V-8 may or may not be like a 304 head.The 304 was popular on trucks and school buses in the 60's so there must be some out there.

 

Take a look at this link, http://www.binderplanet.com/forums/index.php
There is a lot of good information on that site. Look at the club forums down the home page, may be one in your area.

 

Not all the 304s have the small heads. But, point taken...I was actually just referring to the fact that Navistar dealers even now still service the gas engines, so ya never know what they might have.

As far as that goes I was in a machine shop recently that had some long-abandoned IH cores lying in a corner. They are out there, particularly so as the castings have a fairly high percentage of nickel & tend to last without needing machine work for a long time.

 

great thanks for all the info guys!
