1999 C4 Tip, 67000 miles of which i did 5000, no failures of anything (unless you count a knackered air con pipe caused by some over enthusiastic bumping up a kerb!)
...and a 986 before that (woth including Boxsters to increase the sample size?), owne from new to 20000 miles, again no failures

Out of a total of 42 996's:
- 16.6%, or 7 cases, have had engine failures at an average of 70,000Km
- 52%, or 22 cases, have had RMS. When you have it, you get it on an average of 1.4 times.
From those that specified the engine, 19 3.4s and 19 3.6s participated so far in the survey.
- 38% or 16 cases had none of these two problems, with an average of 57,000Km (9 3.4s average 80,000Km, and 6 3.6s average 30,000Km)
The rate of engine failure is decreasing, although not spectacularly. Same for RMS.

:cheers:
.. Interesting to note that there's nearly as many 3.6 as 3.4 failures.
I know there's a general perception that the 'facelifted' cars have more reliable engines , but I was told by an inside source a few months ago that the failures (when they did happen) were fairly even across the board.
I still feel the only weakness of this thread is that peeps will be more interested in posting if they've had an engine failure... The longer we can keep the thread alive the lower the failure rates will go.
Dazren , have you considered sticking the topic for a month or so??

I thought the same. A Porsche mechanic at the dealership here strongly believed that 2002+ models are of better quality mechanically, but the stats here don't really show that. Same numbers although these are 3 to 4 years younger... Interesting to note that there's nearly as many 3.6 as 3.4 failures.

The failure rate was actually 14.6% when I posted , but meanwhile TheMonster entered his data prompting me to edit my post back to 16.6%..Kay

This may be a little cynical of me but the lads to talk to about failure rates are the indies , they don't have an axe to grind. OPC's may stop talking up the face lifters when they don't have them on their forecourts any more ... Then it'll be a case of ' the 997 has the much more reliable engine ' , even though it's been taken straight out of the 3.6 996... Cynical mode off......

2003 C2 owned from new. Just had RMS fixed (noticed after service in May). Got goodwill payment from Porsche (didn't even need to ask for it) and all it cost me was £80. Other than a flat battery (from 4 weeks of non-use) hasn't cost me a penny in repairs.
fulham, what is the mileage at which the RMS was done?Kay

Like you both, I've heard the problems have not gone away, but I'm not sure any Indies will be prepared to put their names to stats of this nature and then have them posted on the forum. Let's see how this develops and hope people continue to post!

And my contribution:
996 C2, yr2000 (3.4), original engine, replaced clutch at 52k, and RMS with it though it hadn't failed.
Car is going strong and looks fresh - still impresses me with its ability to take everything in its stride - from snow covered roads in Chamonix, muddy fields at Le Mans, smoking tyres on the 'Ring, Munich to Basel at a steady 150mph, and simply getting me around the shitty, it has never missed a beat.
