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

There's a guy in our area that is book smart in a lot of things but doesn't have a lick of sense when it comes to cars. His car overheated one day and cooked over and the only thing he had with him was a 2 liter of coke. So he thought, its liquid, it'll work. So he dumps it in and I forget exactly what it did to the engine/cooling system but the mechanic did an overhaul on it and then told him he's gonna put synthetic oil in the engine and weld the hood shut so he can't screw it up again!! Lol
