Leaking AGAIN from the reservoir/manifold gasket. This is an almost yearly occurrence. I've tried OEM, and I think every aftermarket brand. Tried with and without gasket sealant. I stripped out another bolt on the manifold today, and replacing it with a helicoil was an adventure (the bolt hole is shallow). Anyway, noticed that the replacement gasket has 2 slots in it, where the manual shows a gasket with one slot. Since the other slot dead ends on the reservoir, I didn't think that that was the problem, but now I'm not sure. I've had the manifold resurfaced, and though the reservoir is now a few years old, it leaked after the first season. Any other 470 guys have this problem? Am I using the wrong gasket? It always leaks around the aft 2 bolts (which is where that rogue slot in the gasket is)
