Porsche Engine replaced under Warranty

Hi All, I have a late 2001 996 facelift Carerra 4. Whilst researching the vehcile's history, I discovered that Porsche GB replaced the engine under a 'Goodwill' gesture in June 2005 when the vehicle had only covered 27k. Although I was initially wary of this fact, upon speaking with experts far and wide, I was advised that this could only be a good thing. I am yet to check yet, but I suspect that I will have a new engine number. Anyway, my question is to know whether Porsche replacement engines from 2005 had the bigger, more robust Intermediate Shaft (IMS), or were they simply a replacement of the same engine? I have read various reports on this and cannot seem to get a consistent answer. I'm not so sure Porsche would offer this information. Unless someone knows otherwise? I have also read that the IMS problem was still an issue on the first generation 997, and didn't really get sorted until around 2007? Any knowledge/advice on this would be most appreciated. Thank you. :?:

They would have used a MY2005 (Aug 2004 revision engine).

Throughout the 996 range the engines went through loads and loads of minor revisions. You can see this reflected though the part numbers. In terms of your fitment, it would almost certainly be a late 996 model as suggested above. Unfortunately the IMS and cracking problems still exist on the 996 and 997.1 engines. It appears that 997 engines also have a problem with cylinder 6, due to lack of coolant flow, so perhaps the later 996 engines are slightly better - although that's hugely subjective, especially as the 997s have some uprated parts within them. 997.2 engines are supposed to be much improved, but it's too early to say with any certainty. Cheers, GD

997.2 are supposed to be better as they do not have an IMS........but then they hve direct injection which has its problems.

I think the sweet-spot would be a last-of-the-line 997.1 Turbos or GT3s. Proper GT1 block derived. All this 3.8 nonsense (with or without DFI) does my head in.

HI GD, I had this whole thread going on the IMS shaft failure for 996/997's after being advised of the potential pitfalls. See the link below: http://www.911uk.com/viewtopic.php?t=57635 I spoke to Hartech at length about this issue. The most important thing to remember is that even if they were to give you a lifetime service plan, they still are not of the opinion that it is necessary to change the Intermediate Shaft and bearing, as the problem is not consistent enough to warrant it. In the wide amount of cases the 996 is a solid piece of operating machinery. That all said, if you are unlucky enough to suffer from this issue then they can rebuild your engine for less than the price of a new one, and make sure the replacement shaft and bearing are aftermarket stronger components. One of the guys on 911UK with a beautiful car had this happen to him - (SpectralUK). The engine was replaced and he has the most astounding example of the 911..he knows how to drive that thing, and it knows how to bite him back! I would say if you have a replacement engine then enjoy it and don't worry, just keep an eye on the levels and make sure you check coolant levels and oil levels with the dipstick not the unreliable oil level sensor in the car. :thumbs: :bandit:
