Good luck with that.

 

05 c2 no issues at 21k
Also we have a 01 boxster no issues at 38k

I'm seriously thinking of Changing to the LN IMS in the 997 and selling the boxster before it self destructs.

 

2005 Boxster (987) - 45k miles - No IMS Issue (RMS leak fixed but no IMS). Knock wood.

 

06 C4 45k, no issues

 

07 997 C2S, daily driver, no track time, 1 quart oil per 3K miles, ~75,000 miles IMS failure, engine rattle prior to failure. Traded car in for 2010 997 GTS.

 

^^^^and here I thought that I was safe because of high(er) milage..........

 

06 997 S
33K Miles
No problems

These discussions and related articles in Excellence suggest to me that I need to enjoy my Porsche more often before the engine craters. They also have got me thinking about what I'm going to do when my extended warranty expires in 2013. While the odds of failure appear low, footing the bill for an engine replacement on what would then be a 7+ year old car would suck.

Never underestimate the power of denial.

 

Hmmm, this is the first time I've seen an '07 with an IMS failure documented. It's almost always been the '05, on rare occasions the '06, and now this '07.

 

2008 C2S w/ 6K miles as of Oct 2011 - NO IMS issues to date

 

I've noticed that most of the cars in the poll stats have very little miles on them. Maybe we should have poll of over 60,000 miles to get a more accurate idea of failure rates? LN Engineering seems to recommend that their IMS replacement bearing needs to still be changed out ever 50,000 miles.

 

06 C2S with 38k miles, no IMS failure. I did have IMS leak that was fixed under warranty last year

 

09/05 C2S build. 25k miles. Had the RMS replaced and the IMS flange packed (=??). No problems. Runs like a dream. It's a beautiful machine.

 

2005 IMS failure in 2008 with 16,500 miles (first owner). Warranty replacement with 2008 rebuilt engine. Now 20000 miles. I am third owner.

 

early '05 c2s, 22k, no issues with car at all, maintenance has cost less than my f150 (except the cost of tires)

for what it is worth, local dealer has only replaced 1 engine since 2005 and that was questionable circumstance (abuse)

this particular car has special meaning for me (my wife bought it for me) though this does concern me enough to at least be thinking of trading (or is it rationalization?)

 

I have an '05 C2S Launch Edition with PCCBs, so this is an early release (9/04). I bought the car just over year ago with 41K miles, clean PPI with no warranty from a private party. If anything will go wrong with this 'year to avoid' model, then I suppose it will. However, it has been great with the exception of the battery cable, AC vents clip, exhaust tip and heater/fan **** which were addressed under warranty as expected - previous to my purchase. I purchased the car knowing of the potential 'IMS' issues. If the engine goes, it goes. I haven't pulled the trigger on an LNE IMS upgrade (assuming my engine qualifies for the upgrade). Even so, I'm not sure I would upgrade. If the engine goes, then I just replace it with a new one albeit with a few internal goodies - NA of course.
