... failure rate of the TechnoFix DOF is zero.
Units sold to date just over 1,000.
Miles driven I would estimate 1,000,000.
The only way to really inspect wear on a bearing is by cutting it open to inspect the inside of the races.
Happy DOF'ing,
Pedro

I REALLY don't intent to beat that dead horse again, but, before we ponder "the failure rate for the IMSB DOF retrofit," do we have any REAL DATA on the failure rate of the 986 (or early 987) IMSB? I'm NOT a denier. I recognize that there have been a significant number of IMSB failures and that the consequences of IMSB failures are serious (maybe "fatal," considering the market value of 986's). But, statistically, what are we talking about? Consumer Reports hasn't given early Boxsters particularly bad marks for engine reliability, and Michael Karesh's TrueDelta website doesn't indicate that IMSB failures are all that common. So is this just internet-enabled mass hysteria or is there a quantifiable justification for spending $1000 (+/-) to prevent catastrophic failure of a $15,000 (+/-) automobile?

The numbers are not wags. I'm sorry, your anecdotal evidence, based on a very small sample of cars you have serviced does not trump evidence which was compelled pursuant to a legal proceeding where Porshe was forced to disclose evidence on hundreds of thousands of cars. It's incontestable that the numbers which Porshe had to disclose are what they are. And what are you saying? The numbers you quote are very close to the numbers that Porshe discloses. Both you and porshe agree that dual rows have a very low failure rate and single rows have have signifant risk of failure which warrants proactive measures.Does a 2.5 % failure rate according to you versus less than one percent according to Porshe mean that you have to replace t he IMSB tomorrow? Would anyone say I have to replace my IMSB tomorrow because the chance of failure is 2% as opposed to less than 1%? I don't understand why you contest Porsches numbers.Quote

... did not offer any official numbers on failure rates, except talk about a 10% general number.
All of the sub-numbers are just conjecture and WAGs.
From what I've seen, IMS bearing's failure rates are:
'97-'00 cars about 2.5%
'01-'05 cars about 14%
'06-'08 cars about 1.5%
'09 and newer are 0%
Unfortunately the numbers mean nothing ... Pedro (Odessa, FL) - 9 years ago |

I'm working right now on a 2002 Carrera with 7,000 miles. The owner had never heard of the IMS issue.
He's in for a clutch replacement but because he never knew about the issue he doesn't think spending an extra $800 in the DOF makes sense.

on at least one UK Boxster/Porsche forum about how crummy the new engines are. You want to see a British Boxster owner get all pale and weak in the knees just say "bore scoring".
Now understand I do not buy into the opinion the new engines are crummy or even have any real weakness, but it is hard to offer any counter opinion/argument when so many owners seemed rather pleased, in some twisted/perverse way, with the idea that the new engine is no good.
Based on what I have read there appears to be no real science behind the claim the engines are crummy, just the usual few failures that appear to me to be extrapolated into a 100% failure rate in hardly no time at all unless one signs up for some kind insurance/extended service contract, which a good number of UK owners appear to be doing. Then of course, they are completely resistant to hearing any challenge to this new engine is bad refrain as they have money bet on its being bad.
