In reality, how often does the elbow go bad? I'm thinking of re-using my old ones. Of course I will inspect them. Last time I had one off, it looked like it had a fair amount of rust on the inside, but nothing significant like the manifolds do. Mating surface looked good, I did take a sanding block to it before I put it back together and have had no problems using the metal volvo gaskets and a coat of copper spray on the manifold side. I will of course inspect them again while replacing the manifolds. Seeing as they really don't allow water to sit in them like the manifolds do, and this is a non-salt water boat, I'm thinking I will be fine. I'm going to go with Barr manifolds at $275 a piece including shipping. Barr does not make my elbow. So I have two options if I did want to purchase new. GLM at $160 a piece, good price but supposedly scary lack of quality, or VP @ anywhere from $300-$650 each!!! This seems to be the bummer with owning a Ford EFI engine.
