In Spain, in our Soloporsche.com community (the largest Spanish-speaking forum on the internet), we are trying to give up a solid step against the M96 engine failure.
First of all we are compiling several dozen examples of IMS failure, all of which are from soloporsche users, and we have started threads to obtain more information. Porsche AG workers have also had the chance to come into the discussion as anonymous users to explain the real percentages of failures and what they really know. (With Soloporsche admin checking the details of new users to avoid 'trolls').
So are the people suffering hysteria over the M96 engine failure? No, they are not.
We have a lot of friends with engine failure and we know that the M96 engine is a complete design error. Engineers in Porsche Motorsport division, and the mechanical experts have told us the real thing. Wendelin Wiedeking is principally responsible. He tried to raise Porsche's profits and develop a new platform (M96) to substitute the previous air-cooled family of engines. This engine was developed in half the time required and with half the budget. Porsche was in financial trouble and the Boxster and 996 were the two new models to be the angular stone for the new era of benefits. Low cost materials, an IMS that was never to be born (as the new DFI engines), misalignment shaft problems, different expansion coefficient materials, low cost aluminium frames, and a shaft that works in false steel case that is closed in twin-aluminium cases.
Engines derived from the GT1 block, as used in the GT3, GT3 RS, GT2 and Turbo were too expensive to produce in mass numbers. If Porsche had decided to produce a lighter version of this block to be used in the Carrera models, surely it would have been the best decision, because we would never have heard anything about blown engines. It would have also caused a huge decrease in Porsche's accounts due to the high cost of using this engine.
Porsche AG let this problem with the M96 engine run until it updated it for the M97 engine. It allowed 11 years to pass – so much time keeping the wrong thing. Meanwhile, there are a pile of blown engines in Porsche's history, and what's more, there is still a pile that are going to fail.
I prefer to listen to Porsche's experts, not urban legends. I'm a bit tired of reading that the failures are only a very small percentage, and what we have to do is to enjoy our cars. I've seen several failures with my own eyes! What would think if a Porsche expert told you the best thing to prevent the failure is to reinforce the IMS with a solid kit? (I'd like to point out that I don't sell anything myself and I don't have any commercial interest). But what can we do if we're out of warranty? Pay for a rebuild engine or throw away the car? Porsche should give us a new engine every time one fails.
As a Porsche community we are trying to compile more data so a number of Soloporsche users can take the matter further in the courts. Everyone knows that it's far too difficult to prove that it is a failed design, but we are very angry to read about yet another blown engine every week in our small Soloporsche community.
I enjoy driving my 996, I live it and I want to keep it for many years to come. I reinforced the IMS with a hand-made kit, use a race lubricant. With Solorporsche , an expert motor engineer is developing a solution to the problem but it won't be ready for awhile yet because it needs several tests, but if it works it should make the IMS 100 per cent fail-safe.
Nevertheless there are thousands of failures reported on Rennlist, Renntech, 6Speedonline, Pistonheads, Rennteam, and so on. We have also lost of articles published in Total 911, Excellence and GT Purely Porsche magazines talking about this problem.
We want results and to get this we need to combine the efforts of all those effected, so all contributions will be welcome.
