Re: Intake manifold crack in heat riser

The damage (erosion and cracks) looks like what results from a lot of driving with valve stuck open. If you do find someone to weld it, then assemble the manifolds as a unit and have the faces surfaced-ground where they mount to the block. This is good practice in any case but even more so now as the welding may induce some additional warping.
