Well, that was a good post.
Hi guys, I haven't been here for a while, but I still love you all! My 95 Sport, 351 is leaking on the starboard side. I replaced the gasket. Replaced it again with RTV. still leaking...pretty badly. I'm running in brackish water, so this is especially not helpful to my engine block. What are next steps? I thought I'd prepared both surfaces very well with block sanding, making sure to keep everything straight/even, but it's apparently not good enough. Do I need to take it somewhere to have the manifold ground down a bit and leveled? Skied this morning anyway.

You must be talking about the riser to manifold gasket leaking.
If it's leaking externally, it may be leaking internally too, but you can't see that happening. You could pull the plugs on that side and turn the engine over to see if any water comes out and also look for water on the plugs. A machine shop planing job on the manifold and riser would be the second best solution. First best but pricey
 Not knowing how many hours on run time you've had in brackish water, you might at least think a little bit about maybe getting new manifolds and risers depending on how ugly the internal water passages look |
