987.2 DFI engine issues?

From the 986 forum with pics from Jake Ruby: FRS DI issue - grass is not greener - 986 Forum - for Porsche Boxster Owners and Others Has anyone heard of the kind of premature wear in the cylinder walls--or related issues--that was discussed with this particular 2012 CR? Since I've got a 981S, I assumed most of the Porsche engine issues have been resolved with the introduction of the 9A1 motor..true?

Um, you saw the root cause, right? Missing o-ring on the anti-aeration system? Methinks that's a mistake, not a design flaw. ed

Exactly. 'course some will blow this up to an inherent design flaw -- actually some already have on other boards but still offer "insurance" (for a tidy sum) to the scared... -- and have owners shaking in their boots over this. Also, I wonder how the owner would have made out had he taken the car to the dealer? The car I think new enough to be covered under new car warranty.

Yep, I saw that and it seems reasonable on this particular car, however Jake went on: "As we get evolve the 9a1 engines we have also found valve guide wear and other issues. We already have 3 years of development under our belts with the 9a1 DFI engines and the deficiencies are becoming more clear with each one. Others won't see these issues for 5-6 more years, more than likely." Sounds like he thinks there are other issues with this motor; have there been any other reports? I haven't see a one...

Something's odd, guy has a car under warranty yet takes it to an independent and pays for it? Suddenly now the 9A1s are "troublesome," seems to me as the diminishing return on IMS equipped cars comes to the forefront, the 9A1 will be the new "scapegoat," the way I read these guys, Porsche is the only car company in the world that can't design and build engines, apparently Porsche engines require "help" from second hand shops to become reliable and functional. This is the first time I read this and I have a strong feeling that this issue will be hyped to make new owners (new possible client base) nervous, while the perps hide behind the old rhetoric, "better be safe than sorry, send us your engine before it self destructs." Please, set me straight if I'm getting something wrong here. Obviously the IMS issue is real and documented, but in no way was it as bad as presented by some, the broad strokes used to paint the problem were border line dishonest. I just hope we don't get a rash of 9A1-itis, no one has presented hard facts, who knows how case car was treated, at this point it's all speculation. I really hope this doesn't turn into a IMS-like scenario.

That's the guy who built my engine. People take their 9A1s to him so he can build them into 4.0L 9A1s. The issues are found when he disassembles the engine for rebuild.

Interesting reading... Jake Raby

Welcome to the Internet where any potential issue experienced by anyone becomes a design flaw and a cause of fear. I spent 7 yrs challenging people back on my 2006 cs engine and they still persist in spreading misinformation. Good luck on establishing any sense of reality in this thread. Me, I'm going driving.

This , to me, is simply an inappropriately assembled engine that escaped Porsche QC. Owner has a warranty issue. Cheers.

Agreed, I'm not saying Flat Six is unethical, in any way shape or form, in fact all I've read are good things, but why would you bypass your warranty and PAY for something that Porsche is responsible for and will pay? And like I asked, are these "issues" popping up on tracked cars, regular cars or being found as these cars are being modified? Again, most 9A1 engines are still under warranty, so why tear them down? Just honest questions.

Most of the pictures in this thread have been seen before. A Planet-9 member (I think "saildoc") is having his CR 3.4 motor punched out to 4.2 by Jake Raby. The 9a1 has been out in the 987/ 981 , 997/991 platforms since MY 2009. Essentially stock engines have been raced by privateers in Europe and the U.S. in a variety of venues including 24Hr races. The Cayman Interseries has tens of thousands of racing miles on these engines. I have not read of a single engine failure. Porsche now uses the 9a1 on every flat 6 powered production car from the base 981 to the 991 Turbo S and GT3 . If Mr Raby is correct, we should start to see trashed 9a1 engines starting to show up and with increasing regularity. If it is a design flaw, there is little anyone can do, including him. Until the engine carcasses start piling up, me thinks he's just stirring the pot.

I present to you the 991 GT3. They have reached a point where the engines are simply in need of replacement. Some cars have had 2-3+ engines in them... and we're talking 2015/2016 GT3s. As someone stated, it would take years for the community to realize it, but the issues have come to roost. How many 15-16 gt3's have engine replaced? - ******** Discussion Forums (skip to page 101 for time's sake)

thanks - sounds like a pretty darn good record for your Cayman .

9A1 are a solid motors. Enjoy
