LOL!
An egg? Don't be daft. I've worked in the sandwich industry as a consultant for the last 30 years and make a pretty penny doing it. You cannot tell me the egg is preferable to brown or red sauces. I have eaten many bacon sarnies, and at no time did I ever consider the egg.
Eggs are funny things, nice to eat and very useful when I had a Imp Husky as that used 6 eggs per 1000 miles in the water system, you could not use sauce for that
It is now metal with a screw hole in the top...it goes all the way through and I have no idea what this is for (neither did the MErc dealer?) other than to let air out when filling up with new coolant???/QUOTE]
Could it be that the hole running right through could be used as an added escape route for the coolant mixture if the thermostat gets stuck (broken/paks-up/ends its life) in the closed position?
Just a thought.
