Alpha 5.0L - Replace manifolds with risers?

[gbarrett]

The port riser on my Mercruiser 5.0L started leaking and I've pulled things apart. I don't see any obvious problems with the manifolds. Do I need to replace the manifolds with the risers? Not a lot of income lately so I'm trying to watch my pennies.

Thanks,

Greg

The riser(s) corroded badly. It looks like something from an alien movie.

Post some pictures of the gasket surfaces of the manifold and the riser.

That manifold doesn't look too good to me. the mating surface is ugly.


(btw, good last name you got there!)
