Jake made a useful comment about the Cayenne 948 lifters.It would be useful to know the part# because the earlier Cayenne uses 996..... 72 just like the updated Boxster & 996 part#-according to Pelican.
For the Cayenne 2003-10 Pelican show:
Porsche Cayenne (2003-2010) - Cylinder Head & Valvetrain - Page 2
So I
guess we need the lifter from a later 2011+ Cayenne ?
