I'm confused by the above statement. Can you please post where you've seen this talked about? I'd like to see what resources are saying that the non-RS .2 is less reliable than the non-RS .1
(you bought a non-RS correct?,... so I'm assuming we are talking about non-RS, correct?)

I think maybe you also meant "reliability", verses "liability"?

Thanks

Ft Mason?

Haha. Thanks for the correction. Reliability. My phone's keypad and predicability calibration has been way off recently.

bweSteve

but a .2 is less reliable than a .1 ?? ... in stock form?

pissedpuppy

unlikely, I'd guess

bweSteve

I guess I was just hoping mdosu could post up some sources or other threads discussing that point. Seems as though he read it somewhere & was using it as foundation for decisions.

Was just the first I was hearing about it. And I have attempted to capture many of the "problems" that have arisen over the last decade+,.. & I don't have any data that supports it

.1RS vs .2RS, maybe? The camshaft actuator bolt failure to my knowledge affects the .2RS, but I haven't heard of it affecting the .1RS. This is due to the larger displacement with the LWFW from what I understand.

.1 GT3 vs .2 GT3, I don't think there is a difference as the DMFW does help with preventing the camshaft actuator bolts from backing out. But I'm guessing it still could happen in some very uncommon cases.

But again, I have a .1 GT3, so I'd let someone chime in that his more knowledge.

For 99% of people, I wouldn't be very concerned. The Mezger platform is a very solid one and especially with your .2 GT3, as long as you keep it stock (no LWFW), you shouldn't have issues.

Here is one example of a .2 GT3 that was on BAT that had an engine rebuild due to the camshaft actuator bolt failure. Remember though, we're talking about one off cases, I wouldn't tell anyone to not buy a .2 GT3. Just like I wouldn't tell anyone not to buy a CLK63 Black because of head bolts.

the Mezger is extremely solid, with a bunch of motorsport history behind it

I'd also say that within the Porsche range, the 996/7 GT platform is one of the most solid.

Let's think about it this way, every single car and definitely every Porsche has some issue with it that is catastrophic in one way or another. Keep in mind, none of the below failure are common, so again, I wouldn't tell someone to not buy any of the below models, they're all great cars. Even though our family did have a 986 Boxster with a IMS bearing failure.

996/997.1 IMS bearing/bore scoring.
997.2/991.1 have the potential of bore scoring from my understanding, they also have PDK failures which can run $8-25k it seems.
981 GT4 3rd gear failure, which yes has been warrantied/recalled along with strut tower failures.

Now obviously, these issues above are all incredibly uncommon. So I am not saying that any of these cars are bad. But the 997 GT Mezger motor pretty much has one issue and it's not what I would consider the end of the world, it's coolant lines. You can easily do them prior to having a failure and even if you have a failure, unless you crash, the worst that happens is you need to tow the car to a shop and have it repaired. Provided that you turn the car off before it overheats. Granted, we can go into weak diffs or other problems, but that is not a drivability concern, you can still drive the car with an open diff, etc.

The 997.2 GT camshaft actuator bolt failure seems very uncommon and not one that I would lose sleep over. If I was genuinely concerned a call to Dundon would probably provide some peace of mind.
