Welding cast iron is very dicey at best. Totally luck if you get there or not, due to residual stresses, after cooling ,as steel and cast iron expand differently ; that leads to later breaking. They are small enough that a specialty shop might be able to braze it? much lower temps involved at repair.
I have often wondered why someone does not make a steel tubing version of those ; a tight steel bend and two brazed or tig welded steel flanges? . Not a good place for cast iron and the flanges are too thin as they made them (in my opinion, anyway.) .
Not sure that helps you , I know ?
be sure heat riser valve is working right. Overheating not uncommon with frozen axle on that valve , aggravates all this.
Hi 300 ites,
Looking for a set of cast iron riser for my F that attach to the exhaust manifolds, can't put the rams on till I get both.
Jeff Carter does not have any. having casting problems.
I have the risers from exhaust pipes. I do have one that is cracked and one missing. Might be able to weld the cracked one( drivers side) missing passenger side
Any help would be appreciated.
