Yesterday we received 5 failure calls, all but one of them were from 3.4 base engines... 5 calls in one day is a new record, puts us at 7 for the week which also tied the record, but we still have today to go.

The 3.2S engine from 2000 is one of the best IMHO, Dual Row IMS bearing, late IMS drive chain and larger capillaries inside the cylinder heads make it show up less here than all other Boxster engines combined. It also has the most substantial cylinder walls and they very, very seldom ever have cylinder issues.

This comes from trend data collected and first hand experience supported by years of research.

Jake, just to clarify you are just referring to the 98-2001 3.4, correct? And I think the late IMS drive chain started in 2001?
