Wild Ass Rumor of the Day: Porsche Boxster Engine Failures?
Are you aware of the appalling rate of Boxster engine failures, which I’m only now becoming aware of through participation in some Boxster forums? Some estimates (Bruce Anderson, for one) are that 20 percent of Boxster engines don’t make it past 100,000 miles witout a catastrophic failure. The standard failure is what the cognoscenti universally refer to as the IMS–the intermediate shaft. It’s apparently bolted together, and the bolts fail, then everything internal claps hands and you’re looking at a replacement crate engine. I’m hoping the fact that Susan never revs past maybe 4,000 will spare us, but I’d be careful if I were you. There was a recent Porsche Club event that 11 Boxsters participated in. One had an IMS failure during the event and two of the other Boxsters participating had previously had their engines replaced due to IMS failures. Three out of 11 equals 27 percent. It’s a quiet secret within the Porsche community, and there are reasonably knowledgeable people who claim these engines were built as cheapies to get through the warranty period unscathed–which the apparently often don’t–and that PAG hasn’t the faintest interest in second, third and fourth owners. And they used to say the entry-level Porsche was a used Porsche.
