    We have seen two 8.1s this year with this same issue. The seal is on the bottom of the heat exchanger at the front where it is clamped down to the riser. When replacing the seal check to make sure the sealing surface is not bent (usally the reason it isn't sealing well) If it is you'll need to straighten it out.
    We are stocking the seal if you need it at AK Frontier Fab. 907-357-9324
    Best of luck on the repair. If you need help give us a call.
