When I resealed that front cover of mine, I installed a new gasket, that long piece of spaghetti, and lightly applied red rtv, no more leaks!

That old gasket, I expected to be pinched somewhere, it wasn’t, so like you, I figured the front cover was a bit distorted. The rtv did the trick. And that is one thing I noticed on Quickserve, I recall the assembly instructions stating to NOT use any kind of rtv or liquid gasket. Don’t know.
