Dennis,
I have never seen a head gasket as poorly
designed as in our vanagon water leakers. The rubber
gaskets that acts as a head gasket is poorly fitted
for a fixed distance that does not allow shaving your
heads. The only real advantage is they are designed
to leak or seep for years before the rubber becomes
hard and fails completely. I think this is why VW put
the "no phosphate" tag on the back of the tank.
There is no problem with a small leak that will seal
up after the engine get warm, the problem is the
corrosion that occurs when the dried coolant eats at
the heads. The green stuff is a problem(phosphate
salts) where the orange stuff is more like a
detergent.
CarTalk click and clack says that you can mix the
different types but we know what they think of
vanagons so I would not trust their intenstions on
this issue. Gary
