RE: Engine turned charcoal grey
Well, you did do something to the engine and you wanted help to undo the damage. As for your name calling when you used 'chemical freaks', that is out of line. Maybe you should have been a little bit of a chemical freak yourself before you ruined your engine with something like oven cleaner. Sheesh.
edited to add: If it were my engine and it looked that bad I guess I would toss it too.
