David, Just out of curiosity, when you say "pressurized the cooling system", what do you mean exactly? I mean the reservoir is supposed to be pressurized anyway correct? I'm new to this Saab thing (see my previous post) and am still trying to learn the details. I think this 900STD has a small head gasket leak and is allowing some oil into the cooling system, but not alot and I was wondering how much pressure is too much. -Jeff David Taylor <> wrote in > Just an update... > > Recap: This is the car with the head gasket that was replaced by an > independent.
