Perhaps I should elaborate.. I'm concerned about the state of the bleeder valve, and the fact that all of my 80's Porsches have had cadmium plated bolts.. did Porsche stop using corrosion resistant hardware to save money, or is this a generic replacement that has been put in?

There are plenty of examples of Boxster owners thinking they had filled with coolant but were actually very low.It may be a good time to replace all the coolant anyway. 5 years is the max recommended by some. It is a serious issue to attend to with lots of info and care. Easy to screw up unless you have this equipment:

I have been planning on revamping the cooling system for some time now, so I have been through those articles (except Pedro, I cant stand the site layout). But I don't want to spend so much on coolant unless I'm sure the rest of the system is up to stuff. There is no way to buy this Airlift kit, is it something I rent from the auto parts store?

I suspect the coolant has no corrosion inhibitor left, not a pleasant scenario.......

Distillation is the obvious cause of the condensation, it has been affecting these bolts for years through a faulty coolant cap.. the resulting "vapour" is essentially water. And my coolant was green, not brown.
Nice post count btw :dance:
