My pampered 2000 Boxster S had an engine failure due to a cracked cylinder head (1-3). I've done the investigation myself, including making of some of the Porsche special tools. I have created a website to document all of my progress and findings, including a VIDEO of the leak in action.
If you own a Boxster that has had a cracked cylinder head, PLEASE post a comment on my Blog on my website! If this problem has affected enough owners, I will persue a class action lawsuit against Porsche.
Happy motoring!
