Hummmmm. Mite be worth a try with some silicone until I can really do it. Just smear some at the seam or loosen the manifold, smear it and then retorque it?
I don't know on the plug yet. I hate pulling that 1 plug. Always seem to hit my knuckles on something back there.

On my '56 Biarritz, the car acted like it had vapor lock, but indeed it was a leak at the intake manifold. It was detected at idle by spraying something, the RPMs rose for a moment. Strange that you cannot replicate that during idle.
I doubt that you can seal an intake manifold with silicone as there is almost no space to go around the joint with the finger.
