In fact now with the advent of 3D printing, you could make some caps with grooves with an o-ring to seal against the pipe and cam cover... Or a less fancy idea is to just make a silcon mold to seal around the hole and pipe.

I would think smearing some grease on the pipe and ide of the cover will allow the mold to form a seal to prevent water ingrese.
