I can't help but wonder how a rod bolt issue calls for a replacement engine.

I'm getting pretty tired of the doom and gloom depreciation speculations. Unless time demonstrates that the complete engine replacement proves to be a problem, based on actual events, and not perceived notions of what will happen, lack of warm fuzzes, or simply because "it got a new engine", the car will be and remain a very desirable car. Who knows, maybe this engine will turn out to be one of the best ever manufactured, given the scrutiny. Face it guys, we are investing in high performance, street legal cars. We're all too eager to boast about the 9k RPM and 100 millisecond PDK, but are not willing to deal with issues of first generation engines. Anyone see F1 this weekend? The 4 time Champion along with the race favorite sat it out because of reliability issues they are experiencing with new technology. So, if you don't want these issues, don't look for 9k rpm cars that shift faster than your next pessimistic thought can come to mind. I'm as unhappy as the next guy. My car has been sitting for over six weeks in Germany waiting to get shipped. I'm keeping my hand and calling the bet.

^the labor involved tearing into motor > than engine swap. U still have to remove motor and put it back in if you're rebuilding. Motor swap is just take out old and put in new. Mike

I do get that. I guess it's Porsche deciding that is the "best" way to fix. It's definitely not the cheapest way to do it.

thats just Porsches way. Apparently they dont want the dealer tech to tear down an engine.



BTW isnt it a bit premature to talk about depreciation? I mean Im of the opinion that the 991 gt's will depreciate at a faster rate than the 997 gt's given the "increased bandwidth" of customers for the 991. However will these NEW type customers, really care or even know that engines has been replaced? Prob not. And i bet dealers will support the market.

As to why they're loosening/failing is conjecture at this point.
Installation/Supplier/Design, who knows, and you might never really know, so wasted energy to stress over it imho.

some Loctite ought to do it

I was going to post my opinions, but Mike in CA already wrote everything that I've been thinking and he's a better writer than me. Thanks Mike.

Perfectly said. Exactly how I feel...I feel for the guys whose cars are sitting at port or at the dealer...at least mine is in my garage safe and sound and I can at least stare at it...frustrating, but I get to at least enjoy it as "garage art!" I took the opportunity/down time to have some better garage lighting installed!

Agreed - my 2011 Cayenne Turbo needed a new engine after 13k miles...traded it in on a 2013 with some options I always missed, and no issues/hit...was a great car, and had a brand new engine. All good! In fact, drove better with the new engine (we kept it for 3k more miles while we waited on the new car to come in)! It was a simple swap, done under warranty. I have no problem with what they have planned, as long as they can get it done in a timely manner. Fingers crossed. I do miss driving this GT3. Definitely tougher for guys like Mike and I who have spent time driving these cars. Hard to have a shiny new toy taken away from us!

The 996 is not a good comparison at all. Look at the values of 996 turbos and they have the GT1 block and no IMS issues. That's why I bought one 4 years ago.

I really thinking swapping out the engines is cheaper than rebuilding.

Besides. Porsche has no choice. They do not have the manpower to rebuild all these engines at once.

They will be torn down, fixed, and be future replacement engines.

"I can't help but wonder how a rod bolt issue calls for a replacement engine."

Who really cares? Thank your lucky stars they are going to that crazy length. It's truly plug and play...

I would feel less happy if they were taking these perfectly good motors apart...

And if the new one fails after I beat the living snot out of it, I'll bring it back for another...where is the risk? For me, for the second, third owner...

In 5 years when its out of warranty, yeah I'm not worried about that.

Am I missing something?

Loctite has nothing to do with it. Rod bolts just take assembly grease so that the torque/tension ratio is within spec. The bolts elongate and the tension within the fastener keeps it from loosening.
