Hello,

While reading a recent thread about choosing a particular 911, the subject of engine replacement came up.

Based on some time in other forums, this seems to be a bit more of a recurring subject regarding Porsche 911s vs. BMW, Corvette, LSx, Mopar, etc.

I'm well aware of Porsche quality, but engine replacement seems like a known occurence along with how updated the management system is, etc.

Can someone educate me on this?

 

your question is like asking if fake **** are a known issue in Southern California...I have been around here and around race tracks a long time and I could count the number of Porsche engine failures on one hand and that would include those that modified the engines beyond their capabilities...perhaps your source of info about Porsche engines should be a Porsche forum...you are now in the right place

 

I own a 2004 Carerra, my first 'late model' Porsche. I did some research on the engine issues before purchase and still bought one.

There are issues with the M96 / M97 engines, primarily an under-engineered intermediate shaft assembly. If you keep a close eye on warning signs (oil leaks, metal flecks in the oil filter, etc.), engine failure can be avoided.

Google Pelican Technical Article: Common Engine Problems and Failures for the full run down.

 

If I may clarify, the threads I read of the "other" forums I mentioned rarely if ever mention engine failures of those particular makes. Porsche isn't mentioned per se, but I came up with this question while on 6speed.

I have spent less time here, yet have read about more for Porsches.

 

I guess it would help to clarify if you mean that the engine required some repair or a catastrophic failure...I was referring to the big bang theory, which is a pretty rare incident...check the Pelican article for info on issues with some specific motors...you will find it usefull

 

For reference, here is a link to the article discussed above:

I experienced the full failure of the intermediate shaft which basically destroys the engine. Replaced the whole thing after 48,000 miles (no race track either). I hope it's rare but I know 2 other guys who had it happen under warranty - mine had expired (in years but not miles) and porsche wouldn't help out all.
