Roland, your response explains why my the rubber boots were destroyed on my pistons. I thought it was just wear but the ones that were torn had the pistons installed at odd angles.
Historically, has Porsche always designed the pistons this way or was this something they learned later in the 911 evolution? I haven't checked other manufacturers; is this design used by all or specific to Porsche?
