Leaking aluminum Mopar valve covers!!!

I like the old school cork. I use 3M weatherstrip adhesive to glue them to the covers, then install the covers. torque very carefully and evenly, they are cheap and thin and can crack easy. I always go center bolt ont eh bottom, then both lower corner bolts, then the 2 on the top flange. I havent had leaks in a while, even when resetting the valves, installing inner springs, etc and reusing them a bit.
