I bought my Boxster 02 a few months ago, It currently has about 64,000 kilometers.. I was just reading about all those engine problems. Thousands of dollars in repairs, whoa .. what did I get myself into ??

Is there any preventive measures I can do to reduce the risk. What years were affected? Do they all have that porous engine block ? What problems happen before the " BIG ONE" occurs !! What do I have to look for?
