If your engine is making noise please STOP!!

There is no internal noise that emits from an engine that is a positive thing... This week so far I have talked to 3 different individuals that could have avoided a catastrophic failure if they hadn't tried to make it home, or to the repair shop or tried to save money on a tow bill. This happens over and over again... Two of the three people have confirmations that their engine can't be saved because the debris from the primary IMS bearing failure has created several secondary failures like bent valves/ busted pistons along with debris circulation that destroyed every internal bearing surface of the engine. The third is still unconfirmed, but based on his pics I'd say its also a goner. All 3 of these people heard a noise and kept driving. All 3 of them had an engine screaming to them that it was about to scatter and send their wallet plummeting, but they kept on driving. When you hear a noise that you haven't heard before you must take it seriously, because you could be SECONDS away from an engine failure. IF you operate from the worst case scenario the chances of your engine being saved are greatly elevated. There are instances where a noise can come from the water pump, idler pulleys or some other component that may not lead to an immediate catastrophic failure but these things also must be taken seriously because any sound isn't a good sound. If your engine screams at you I highly recommend that you listen, else you will pay the price and it will not be cheap. Pay attention, be proactive and shut your engine off ASAP if a noise begins. Do not re-start the engine until it is professionally diagnosed by someone that is familiar with the M96 and its failure modes. Failure to take these noises seriously cost two Porsche owners 15,000.00 each. NOISE= STOP!

should just sticky this on top of the page

But....I think you could be more specific about noise. For example I had a rattling / marbly sound - turned out to be Catalytic Converters...

Not be negative.......but there sure are alot of the 'IMS' issue emails popping up lately. I think it is something to be aware of but I have the sense that some folk are acting like lemmings jumping off a cliff because of a fear factor involved. Trust me, I'm not discounting the fact that LN seems to have a cool upgrade and that a very talented few have decided to undertake the work themselves. I wish I had the ballz to tear my motor apart. But I don't feel the need to tear it apart because I think part of this is a (don't get mad everybody) marketing ploy to sell stuff. I just don't see the frequency of failure that is being talked about on these posts. Now if my IMS fails on my way home, I will be a big idiot and apologize to all. Just my 2 pennies.

That would be a reasonable position to take, Pete, if the marketing and the IMS failure stories had both begun at the same time. Unfortunately, intermediate shafts were failing - and people were posting about it - long before LN Engineering came up with the retrofit.

No marketing ploy here, we can't even keep up with the demand we have for the parts now- no need to try to sell more! I was simply stating that people are costing themselves thousands of dollars by not paying closer attention to their engines and not acting when the engine begins to have a noise that could lead to a failure. The third owner I spoke about didn't have an IMS failure, his water pump impeller failed and the pump stopped moving coolant. The engine overheated. Since I made my initial post he has called back to say the engine has been compromised due to overheating. The noise he heard was the impeller breaking, but he didn't stop and he didn't pay attention to the temperature gauge. Call this a sales tactic if you want, I just hate to see people spending thousands of dollars repairing issues that could have been avoided with simple observation and common sense. If any moderators see this please delete the thread, I don't have time to deal with criticism for trying to help people.
