Yet another IMS "solution"

[Perfectlap]

^ Time is Limited? at 70K miles? Seriously? That sounds outrageous to me. Call me crazy but if your following proper maintenance, letting the oil temp come up before beating on it, did the LN retrofit and maybe are laying off a little during winter, then it seems nuts to think the engine won't last you another 10 years.
But then again...I don't fix engines. I thought I was buying a Porsche not a FIAT/Ferrari!!

I don't think it's amazing at all that your car is running after 12 years with 70K miles. While there may be 20 failure modes, most are pretty rare so 95%+ of the M96 engines last a long, long time. So I'd stop worrying.

The probably of an IMSB failure is very low especially if you change oil more frequently than Porsche recommends. One can improve his or her odds by installing an LN Retrofit bearing when one replaces the clutch. Then the chances of a subsequent IMSB failure become vanishingly small. At worst, one might want to check the LN bearing at 50K miles use to see if it has any play or wear. My bet is that the Retrofit will last much longer than 50K miles.

Second, one might want to replace the chain pads and tensioners in high mileage cars especially if one sees pad debris in the oil filter or sump. Other than that, I'm not sure there is much one can do to guard against the other failure modes.

Hope my 2 cents helps put things perspective.

You didn't get my sarcasm. I think that the car can last another 10 years even without the bandaids mentioned. ...and if it doesn't, it's still ok cause I already got my money's worth....
