    Exhaust manifold

    I found a 47 short hood a year or so ago and am just starting to work on it but the exhaust manifold is broke. I have a newer parts machine { black face } It looks like the exhaust manifolds interchange ? Is that correct ?

    Broke as in parts are missing? Or broke as in it can be repaired?

    How are your welding skills? Grind the weld out and braze, stick, tig, or mig it to repair the manifold.

    F162/F163 Continental will fit either or.

    This thread is from a couple of years ago so price of a new one has gone up from $100 to now $130ish for a new one. Or go with Duane's super awesome repair if you're that awesome. (I am not )

    I think it was member castweld that pointed out a long time ago that older exhaust manifolds suffer from a significant loss of nickel from the cast iron due to heat degradation making it difficult if not impossible to weld or braze.

    I've never attempted it but am fascinated by guys like Fenner and Abom79 that show how it's done on cast repairs. I never knew about nickel loss. A good preheat and right filler I guess can't overcome this? The nickel actually leaches from the iron from long term use and heat cycles? Does it just sublimate from the surface? Something is tickling my memory, I think it was super-missile? Supposed to be a wonder filler for some things?

    Re: Exhaust manifold

    Well as long as they interchange I will change it . Thanks . I have tried fixing and like Duane said I have found some of them impossible to weld and by the looks of the first repair I am going to assume that is the case Thanks again
