I have an older Silverton 31c with twin 318's. recently I started to hear what sounded like an exhaust leak on the port motor. (Last season I had a leak in the exhaust manifold gasket on the starboard motor which sounded exactly the same). This time, I traced the leak down to what looks like the intake manifold gasket on the inboard side of the engine. Its definitely where the noise is coming from, and I can feel gasses escaping. My question is since this is on the intake side of the head, a few inches downstream from the carb base, should it actually be leaking under pressure there? The motor runs fine.
Thanks
