I'm thinking it's not an engine alignment or mount issue. Hours are low 215.
The hatch is long, probably 5'. It only rests at the hinge and two pads at the end of the hatch. Thinking It is sagging a bit in the middle. Stringer of the hatch contacts the aft end of the valve cover. Perhaps shimming the rubber pads at the stern where the hatch rests when closed.
Thanks for replies
