Thanks!! and excellent idea, how comical i was working on my father in-law sailboat Kubuta diesel last weekend and could not get the cooling system to bleed until about an hour of trying. As you indicate I could not get the thermostat to open and the temp kept rising, it did have a peacock on top of the thermostat but as you said above if the tstat does not open what good is it.

I agree 1/8" hole is small enough to not affect flow but big enough to let gas out!!!
