Do you know if this also applies to the later M97.21 3.4 engines? Or they also have the same valve sizes as the 99-2001 engines?
I assume that the increased load on the cylinder walls (w/longer stroke) applies as well, is this correct?
Do you know if the 3.8 engines on the Carrera S also have issues with their cylinder walls due to the longer stroke?
Thank you for your comments!
