The part of the article that puzzles me is the idea that Porsche had a reputation for bullet proof engines and this case will damage it. Probably my age showing but apart from the 3.2 Carrera, their engines have not been that reliable. Head studs, valve guides, chain tensioners, exploding airboxes, carbon buildup and other issues in their history. Even the hallowed Mezger engines are not perfect (coolant hose issues). Not at all defending Porsche on the IMSB case. Just saying for owners it pays to be informed. Lots of info available for awhile now on the IMSB weakness and as noted there are some ways to address it. I still like driving these cars.
