2005 are great cars... not that it was the first time Porsche used that engine... it was on the 996 for 7 years...

people tend to exaggerate the fears with the 2005's

Even Porsche (in their own way) admit there were many issues with the 2005 engines. That's why they have replaced so many engines (gratis) out of warranty. The 05's have the same IMS design as the 996 and that's a very weak link. 06's through 08's have the updated IMS. Not that it can't fail either but it's an improvement..

I had a 996 blow up by the way... It's not very mich fun... :cursing:

They're all good cars... you read about the bad stuff on the Internet... just drive, rev it up, enjoy, and maintain it properly.

Actually, some of the 05's also have the "final solution" IMS, which unfortunately cannot be updated with out a total engine tear down............I hardly call that an "improvement"...............

And before you ask, no, there is no way of knowing which IMS is in the car without taking it apart.

Glad I have a Turbo now so I don't have to think about the " IMS" delimma...

JFP.. Since your in the repair business, how have the first gen DFI engines fared? I haven't heard much about them (as far as issues.)

Pretty well from what we have seen. We noticed that fuel contamination of the oil was higher than pre- DFI cars (as expected), so we have shortened the oil change intervals to reflect what we have seen, and will be logging more data to see if we need to readjust. There have been some occasional fuel pump issues (the DFI cars run 120 bar or 1,740 PSI fuel pressures), but because the cars are so new, they have all been warranty problems. I have also heard some dialog about a couple of problems with the front crank bearings, but I do not have first hand knowledge on the specifics what that is about or how wide spread a problem it is. A bigger concern for us is the total lack of diagnostic support for the independents to deal with the PDK, only thing available is the factory PIWIS lease, which remains exorbitant…….

JFP..Thanks for the info.. I'm sure Porsche will make the 991 even harder for you to deal with....

I can't wait to have to explain the price quote to change the air filters.......................

Rear bumper cover removal to replace air filters.. That seems a bit rediculous. They should make them attach like the nose on an F1 car.. Two fasteners and its's off....

Cant wai to see all the "How do I remove my rear bumper cover on my 991?" questions on the boards in the future....

I bought an 05 C2S last year, and haven't been happier! I did get an extended warranty, paid about $2500 for 3 years or 60,000 km, it covers almost anything that isn't wear and tare. My biggest advice is to have it checked out by a Porsche mechanic before you buy it, they can usually estimate what jobs will be needed and a general timeline of parts that will need replacing. You can also use this information to negotiate the price. Either than that I don't have any of the major problems you see online with the 2005 911. Just like every car, there will be some bad batches or lemons, but if you do your own due diligence you can find a winner for the right price.

Good luck mate

Get an extended warranty, so you'll sleep better. Also, increase your oil/filter change frequencies to 5-10K miles, avoid frequent short trips, and don't be afraid to drive it vigorously in the higher rev ranges. If it's gonna blow, it's gonna blow, but the motors are happier and seem to be more reliable when driven hard. It's more fun too.

Cheers.

I have heard this many time. Is it really better for the car if you drive it hard? can you guys please explain more?? Since I had the intermediate shaft problem and got the engine replaced on my MY05 C2S I've been very careful how I drive it and always trys to drive on low RPM. I push it rarely and only drive it on weekends

please advice.

Thanks

H

your advice is really appreciated

Sure: moderate RPM's during the break-in period, but with the new motor and its revisions that addressed the IMS problems, you can then drive it even HARDER! I'm guessing that higher revs at longer periods means reduced sludge and better lubrication all around. Besides, these are honest-to-goodness SPORTS CARS! Don't be afraid to DRIVE it!

I'm gonna track mine this Sunday at a high performance driving class. You'll be the first to know if I had to walk home!

Cheers!

I couldn't agree with this more! The 911 was developed to be driven hard at high RPM's. I'm not saying to go blast it all the time, but its a sports car, it needs to be driven hard. It took me awhile to get out of the babying phase and start driving her the way she was meant. Its the best feeling in the world, you won't regret it. Also this was advice my Porsche veteran mechanic gave to me, the engines bulletproof, have some fun. :cheers:

I would consider the Porsche guaranty as part of the cost to run a 911, though they have recently put a lot more restriction on what is covered and not by the guarantee

I had this year 1)my tiptronic gearbox changed 2) front suspensions and control arms 3) oil leaks fixed ( required engine removal) 4) main drive shaft replaced

I hear that the post 2006 3.6 model do not suffer from the IMS bearing issue and do not have the piston seizing issue of the 3.8 so it would be the most reliable choice

Take care that the car was produced in 2006 and not sold in 2006
