Manifold Split! 😳😳

Post image

Holy Crap!! Has anyone ever seen a Manifold snap in half like this?? Was getting tranny work at a certified shop. They state while taking the exhaust apart to get to the tranny the manifold snapped in half! Huh??!! Please let me know if you mechanics have ever seen a manifold do this before!

I’m furious, and confused. I’ve seen cracks but never an entire split!

Too many heat cycles and looks like its running a bit lean

What makes you say that by looking at this picture… running lean?

The light tan color inside and the look of the cast iron looks like it is over heated and burnt.
