I have 1988 Viking 671tib. I think the turbo bypass valve might be stuck partially open which then bleeds roots blower air. This unit is a
J&T custom bypass. It is attached at the cylinder 6 position inspection cover. Anyone have any advice how to remove and clean or repair. It also seems to cover a water jacket cover in the head. On top are 2 cylinders about 1 inch in diameter and 2 inch long with
