I like the way that everyone is so negative on the newer watercooled engines, but has forgotten about Porsche's past:
- 2.7 engines that leaked oil new on the showroom floor
- Pulled studs
- Failed tensioners
- Broken headstuds
- Intermediate shaft bearing wear (1968 1/2)
- CIS airbox explosions
- Dry-sump oil pressure / scavenge problems
- 964/993 valve guides (air valve clogging)
- Distributor vent problems
- 3.2/3.3 rod bolt failures
My point is that there have been problems with Porsche's engines from day one, these watercooled ones are not necessarily better or worse. I tend to think that the number of failures has been pretty low, when you consider the total number of cars sold (Boxsters, Caymans, and 996/997s).
Just my opinion...
