Retorquing the heads on these K series engines is pretty much
a standard maintenance item for me. Have never bought one
without blown a blown head gasket. I am a bit anal but usually
torque them every year as an up keep item. Every time, I find that
they have loosened some. Even after many years of use. Have not
blown a gasket since.
Never dawned on me either to just drill a hole in the shroud. Duh.
I'm a bit slow sometimes.
