my .02 , well here we are again, same subject that indeed was talked a lot about 3 months ago, and actually awhile before that, so whats the answer, lots of guys says its an abnormality, very rare, forums are skewed, etc.etc, BUT, the beat goes on , one guy writes in about an engine failure that should not happen, then lots of others write in with similar experiences. Bottom line seems to be we have great cars but when the bell tolls and its engine replacement time -and no one knows when - man - what a way to enjoy a 100k car, a roll of the dice when your engine will fail, UGH, but Im still happy , that is until the grim reaper shows up with an engine failure. So what is the ratio of 997 engine failures to cars manufactured , common Porsche tell us.
