Cayenne Engine Replacement

If you go with new old stock the problem your having currently will eventually happen again. Talk to Flat6 and get it done right and for the last time. Porsche really screwed up the NA V8 with all these scored cylinder issues...

Okay. Here's to my first post. Wish it were on happier notes.
I've got a 2004 Cayenne S (US model) with scored cylinders. It's at 86.000 miles. Located in Iceland, so yeah, low temps.
Ticking started during winter and I started seeing much more smoke (light/white) as well as higher fuel consumption. The smoke was on and off though. Sometimes I'd disappear into it and other days I couldn't tell if the car was running or not.
I had a compression test done a year or so ago, to check for this. It was negative. No ticking then. Can't remember the reason for the compression test.
I've been told the engine is worthless and I should just keep driving it and account for more oil consumption until eventually it'll seize.
The dealership over here has nothing to do with the import of the car, it was imported privately from the US by a previous owner. Still, I've had them write up a letter to Porsche Deutschland requesting free parts for repair. They've told me it's going to be a "NEIN!", making the car worth about $5000 - if I'm lucky. Basically it's a letter for "Good Will", but that's something that's only available to models younger than 5 years. Mine's more than double that.
I've browsed the forums, Googled my way around and to no avail. It seems like this is a common problem, but not one that Porsche will recognize. I just wanted to put this here so other people will know they're not alone with this problem and I'll let you know what answer they come up with.

Its happening more every week... The damage always begins to show it's most notable symptoms when temperatures start to creep up after the cold creates the initial damage.
Its pretty clear that we may need to add a division to only reconstruct Cayenne engines. So far 11 Cayenne failure calls in June alone... All are cylinder failures, whether they have been properly diagnosed, or not.

If you consider that NA V8s outnumber turbos by at least 3 to 1 then a heightened number of NA V8s with a common problem would be normal. Jake's limited stats, however, suggest a bigger problem with turbos.

We have seen huge difference in these failures in the past 2 years, because we had two hard winters in a row, and even as far south as Georgia we saw temps hit zero degrees for a few days. The colder the winter, the more of these we see- period.

12 calls to your store in June so far implies a much greater issue than I'd thought. I suppose it's a percentage issue and as more Peppers get out there, more will fail.
If it were to happen to me, I'd consider a US crate engine instead. Paying $35k or whatever for a Porsche engine installed seems scary and after all, no guarantee you won't lose again with that engine.
Beats me if the swap is possible, tho. Hardly my area of expertise. Also my area of expertise is not putting a $35k repair into a $34k value car.

These issues are not limited to Porsche, we have recently developed a fix for several AMG engines that fail the same way, especially those that are supercharged. Of course this still takes out M96/ M97 Porsches too, and I just one down yesterday with two failed cylinders that came from Quebec.
The rash of failures in June actually occurred in Jan-March across N America, and the symptoms just showed up when temperatures got warmer. This is when the symptoms lead to the engines eating oil, and misfiring, and people that don't know the traits of these failures start to know something is wrong.
By August or so all this year's failures will have exposed themselves, and we won't see Cayenne failure reports till next winter.

These issues will happen all over again with the replaced engine, if it retains factory cylinders. This is why I will ONLY use my running clearances and piston foreign profiles in conjunction with genuine Nickies cylinders.

After all, a Pepper with an LSx is worth maybe 50% of one with a P engine.
