My Wife has an Issue with the 710 Engine Cap...

I worked as a mechanic many years ago, at a Renault dealer if you can believe that. Anyway this car comes in one day and it's covered in oil and antifreeze. The woman's boyfriend had taken the 710 cap off and filled the engine with antifreeze, thinking he was filling the cooling system. When they tried to start the car it blew a fountain of oil and antifreeze out the valve cover, covering the car and blowing all the seals in the engine. We all had a big laugh over that one, while we were doing a complete rebuild on her engine.
