And I mean LOUD!!! It is steady too, no pulsing or intermittent action at all. I have to wear ear protection just to search for the noise. It began suddenly two days ago on a trip. I drove it on and experienced stumbling and hesitation from the engine at lower RPM's. It ran fine otherwise. Dogs between San Francisco and Grass Valley, California are still yowling. It seems like a vacuum leak. When the engine is turned off, the noise dies slowly over a second or two.
Using a pair of ear protectors with a small tube running from one ear, I listened and isolated the sound to beneath the air inlet tubes and near the second cylinder on the right bank.
I'm thinking that a gasket has given up it's "gasketing" job for the winter. Any ideas or experience with something like this? All comments appreciated before I go deeper into the removal of things that I wish that I didn't have to.
