Where did you get the plate? Unless you were rough with it the gasket should be ok it is a metal gasket. Try gettin the bolts tighter. Zacks had a whistle and we
tightened em more and it was good to go.
They All should be fine not really gonna get a bad one I don't think. They are all laser cut so if onefits they all will . Tolerances are tight with laser cutting. I know husker diesel plates fit 2 for 2 with me. But I'm sure alligator sold 100 of em and didn't have a "bad one"
