I most recently posted on Rennlist and was recommended this board as well for more guidance!
I have a 2005 Porsche Boxster (987) with 51,000 miles on it - and have just had an IMS failure. The failure occurred at a traffic light, after 15 minutes of highway driving. The car was not moving when the failure occurred. I had no previous indication of imminent failure - no CEL, etc. The clutch was engaged and suddenly the car stalled. I attempted to restart the engine (because I was in the middle of an intersection) - and got it started, hearing now mechanical clunking/metal on metal. Immediately I turned off the engine, wanting to conserve energy until the light changed. Once the light turned green - I gave her one last start, and got up to about 20mph before turning her off and cruising to a stop. This was absolutely necessary, otherwise I would be blocking traffic in a major intersection. Once off to the side - I called roadside and did not attempt to restart the car.
Once the flatbed arrived, as soon as the car was in a vertical/upright position being loaded onto the bed - OIL came pouring out the back, at this point I was in shock and horror - knowing that the problem must be engine related, as I did not hit anything prior to cause such a leak, etc.
The car was towed to the dealer - and by Monday I had the news - "Intermediate balancing shaft came apart". They proposed to rebuild the engine - for 10k
2,799 in Parts
48hrs/45 -- in labour
That's a dealer rate of nearly $160 an hour! OUCH.
Now, knowing that this was a crazy estimate - I wanted to get an IMS specialist on the job. I had the car moved to an independent shop with lots of IMS experience. As my car was a single row bearing design, he removed and replaced the IMS from LNEngineering - this mechanic is one of the few certified directly from the company, so I trust his work. Upon restarting the car after the upgrade, he reported that there was still too much metal moving around in the engine - and that the engine was officially blown/dead.
The value on the car right now is 21k in good working order, without the engine I understand that I will only be able to salvage 3-4k at best. I have read all the options, and just about every forum post on the topic of IMS failures - but still don't have a clear idea of what the next steps to take are.
Here are my trouble points:
1. If the engine is replaced, I understand it to be about 18k for a "new" one from Porsche, or somewhere in the 15k range for something used. (This is including labor costs).
Is it worth it to do this on a 2005 car? Other options?
2. I have fallen madly in love with this car, and have babied it from day 1. So the interior/exterior are in perfect shape. Also, there is no other car on my short-list for now that I would be interested in. This was it.
What model/year Porsche would you replace with so that this can NEVER happen again? (I understand only 2009--later)
3. Is the dealer serious that they could "rebuild" the engine for that price? Or will they end up increasing the estimate once they take it apart?
4. The car is out of the CPO warranty by about 1 year. The dealership says it's only a 5 year warranty - when stated on the website it claims 6! The dealer says warranty was finished on 4/15/2011. Is there any chance in Heck that they would honor a "Goodwill" replacement or adjustment - as we also own a 98' Boxster as well.
