Hi; Actually there is nothing wrong with the idea of using plastic for this part, just the fact that they used the wrong kind of plastic. Likely the original logic was that the servo unit wouldn't corrode away like it would being made from steel or some cheap metal so they used cheap plastic. Even an aluminum unit would corrode away and leak if the owner used straight tap water in the cooling system, which was a problem with early aluminum engine blocks. Had they used Bakelite or one of the modern heat resistant plastics, like they make throw away baking pans out of, it very likely would have held up. Anyhow has anyone tried to use form a gasket or silicone calk to seal one? What type of plastic did they use for the original housing?

None, to my knowledge. Mercedes used the same plastic servo as Chrysler. However, it was Mercedes enthusiasts who encouraged the creation of the aluminim-bodied, after-market servo made by Performance Analysis. Just like us, they were tired of their otherwise fun old cars being let down over and over again by that nasty plastic. It's surprising to read about one of the aluminum units making its way to a junkyard. It was probably worth more than the car. ;) Dave Duricy 68 Imperial 73 Imperial 50 DeSoto __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
