I have a friend who was an old school VW mechanic. He said that the European flat fours were a magnesium alloy. When they got really clapped out engines, they'd take a couple the cases to a cliff over the Pacific, start it to burning with an acetylene torch and pitch it off the cliff. Water wouldn't put them out and they'd burn bright and hot even under water. Never saw it, but that's his claim.

Wonder how much magnesium in in the Boxster case.

I've always thought that folks who run oil analysis have more money than sense--had a forum friend who would report his engine analysis on his KLR engine every oil change. Gimme a break!
