After clocking over 110,000 hard miles on one Cayenne and at 60,000 and counting on another with no issues what so ever, it doesn't wash with me. Both as tight at mileage as the day they rolled off the showroom floor!

Unfortunately, I would not consder myself Porshe's "Bread and Butter" nor Ignorant, but thanks for your input.

I was merely making a statement that if you are so concerned that your engine will suddenly sieze than maybe you should not drive a Cayenne or any car for that matter. I would not own the Cayenne if I was unable to work on the car myself. I have done the brakes, brake bleeds, coolant pipes, plugs and coils, and all the oil changes myself. I have also helped others with the Carden shaft replacement. No I would not be able to replace the engine myself but the car is now seven years old and not worth the 85K when it was new either and I consider it worth the risk. I bought the Cayenne almost five years ago and have not had any issues other than the items above (replaced pipes as precaution). I enjoy working on my cars and understand and accept that they all need maitenance. I had a 914 in High School and rebuilt the engine myself as well as painting the car, those were the days of easy to work on cars.

Sorry, I am not a guy with too much money that can go buy a new car every year and if I was, I would not be driving a seven year old Cayenne.

not to thread jack but is the cayenne 6 cylinder really the VR6 with 15 degree vee??!???

It's my understanding that the Cayenne uses the VW/Audi 3.6 liter VR6. Whereas, the Panamera has a Porsche developed 3.6 liter V6.

What models?

It seems like every car that Porsche ever makes is considered a ticking time bomb for one reason or another. The 996 guys worry that their IMS bearing will fail and destroy the engine. The Cayenne guys worry that coolant lines will burst or that cylinders will be scored or whatever. Again, it will destroy the engine.

You can't get too caught up in this stuff or you'll go crazy. Solutions tend to arise for legitimate issues. Get the car fixed and keep driving. My Carrera 4S is 12 years old with 129K miles on the odometer. It's a solid daily driver with no major issues. My Cayenne S is 10 years old with 130K miles on the odometer. It's my wife's daily driver. It's also a solid car with no major issues.

If you are really worried about a car being a ticking time bomb, then you probably won't be happy with a Porsche or Audi product.

True. I read that Al Qaeda has been stocking up on them. I strongly suggest that people not remain in any area where they see any Porsche vehicle.

Do you mind sharing more info on this?

Does this apply to 958 V8 or prior generation? Did Porsche make any changes to the V8?

I am looking at getting a 2015 GTS and is planning on keeping it for 100,000 miles plus.

Any input on this is greatly appreciated.

If you live in a Nordic climate with severe cold temps and have a first gen v8 non turbo there is some risk you will see reduced engine life.

while i like the 4.8 V8 I dont love it.

Dyim

So, I assume 958 is OK for now or maybe too early to tell?

endless_corners

Isnt the 958 v8 a new lighter engine and shared with the panamera? The 958 is a 4.8 and the 955 is a 4.5l. I think the original flaw was with some units having casting errors. Porsche MUST have corrected these errors because I dont think the 957 4.8 NA engines have this problem area.. also considering how many units between models are using the new 4.8l Porsche would have to make sure it was bullet-proof.

Dyim

Thanks.

I can sleep better now.

955, 957, 958 and Panamera all use variants of the same M48 engine. From 957 onwards all M48s had piston cooling via oil spray.

JohnnyBahamas

It has been suggested that 955 turbo versions of the V8 might avoid cylinder scoring, so what is the difference between a 955 NA V8 and a 955 FI V8 that might explain the resistance to the issue?

Alms? Alms for the poor?
