Was wondering if the om617 exhaust manifold was cast iron or cast steel. Im figuring its cast iron. I used ni-rod when I welded my EGR shut just to be safe and am considering welding a port straight to the manifold for my external wastegate but would prefer to MIG it if possible as Im not really an avid stick welder.

preheat, clean the surface, and let it cool over a few hours. I've only done mild cast welding though, haven't hacked up my exhaust yet

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

pre heating definitely helped with the exhaust manifold penetration, but in only have 120v mig welder.

Preheat & use stainless wire, then wrap it in a welding blanket.
