cayenne turbo major engine faults?
Discussion
Hi guys
I've been offered a 2003/4 turbo with a list of issues mostly silly bits but the main problem is that it's missing on one or maybe 2 cylinders.
Now I've heard all the horror stories about cylinder liners failing on the v8s
I've also been told that the turbos don't suffer from this?
So in your experience anyone on hear had an engine fail on a turbo?
I'd love to buy it and sort it all out but if there's a chance it needs an engine there's no real point

I have to say since I was a child I have always dreamt of owning a porsche. Now that I am in a postion to potential spend 20-30k on one, I find it pathetic and disgusting that any model I look at basically has this potential problem.
Small problems I dont mind, I dont even mind a fix that would cost up to 2-3k but a bloody 10k to rebuild an engine which by all accounts should be bullet proof is shocking!
Even then I have heard of some rebuilds failing after 2 or 3 years anyway so thats not even a sure fix either.
Surely its not bloody fit for purpose, why there has not been a class action I have no idea.

There has been one in the US and they won.Small problems I dont mind, I dont even mind a fix that would cost up to 2-3k but a bloody 10k to rebuild an engine which by all accounts should be bullet proof is shocking!

Hi Chaps,
I have a 2006 Turbo S - 3 years in.
The Turbos don't have the liner problem.
Mine is currently in for its 90k service, and yes the mechanic mentioned it was missing intermittently on one of the cylinders - so he is checking which coil pack it was.
I didn't notice it - although once felt a small hicup, but that I thought it was the gearbox dropping a cog (downshifting).
In honesty, its been cheap (relatively!) to run.
My car did suffer the coolant pipe issue - it was under Porsche warranty, and they swapped them for me for the new Aluminum ones. To do this yourself, I think its sub £500.
It is a mega car - relatively quick, refined, and well built.
If there is ever a car that can get you into trouble its this car - the straight line performance is way above the cornering and braking capability. 2.5 tonnes is 2.5 tonnes.
Interior quality is a bit of let down, but hey ho - I have 2 kids destroying it daily. I have numerous bits of trim in the garage where they have literally been pulled off.
Just be warned, its seriously heavy on fuel - forget about "its fine on long runs", it isn't. At best you are looking at 19/20 mpg. Full tanks are less 280 miles, and over £100.
We have a 320d for boring stuff.
Anyway, great car, reliable, and still to me at least, looks good (in a G wagon kind of way) , and has lots of grunt.
Just be ready to pay for the running cost - it also chews through tires...brakes..fuel.
Oh and they all burn a little oil, but I now run 5w 50w motorsport oil which has helped massively.
No plans to sell mine - will probs keep it on the side. Once my brats can fit in the back of 997 turbo/GTR, will get one of those as well.
Anything else, just ask.

Hi There,
I have dealt with a fault on a turbo engine similar to this, it was missing and running very badly. The guy who owned it had been told it could be a cracked head, failed head-gasket or cracked ring lands..
We pulled the coil packs and there was oil pooled in the spark-plug tubes, and when we pulled the spark plugs they were pretty grotty. New cam cover gasket, spark plug tube seals and it started and ran fine.
Always go for the easy things first. I have found that some owners can't wield a spanner without hurting themselves or damaging the car... If you want to go ahead get the fault codes read, and maybe do a compression and leak-down test, as this will give you a good idea on the engine's health. A bore scope as well would be a good idea. This could save you some serious cash if the engine is a duffer.
There is some simple tests you can do yourself, if the oil smells of petrol, or if there is a white/beige gunk on the oil filler cap that could indicate problems, also have a sniff of the coolant tank(yes really) and the cap, if you can smell exhaust fumes in there after the engine has been run then there could be a big underlying problem.
Good luck.

The V8 engines can suffer from bore scoreing but i belive its to do with the oil spray pipes blocking causeing a lack of lubricant to the lower part of the cylinders, usually bank 2 ( n/s/f )
Ive not seen that many Cayennes with bore scoreing but i have seen a lot with cracked coils , without a boroscope its very hard to say but they do tend to rattle if its bore problem.
One of the problems with reading forums i think is that people that have major problems will post about how bad the cars are .. i dont think the average owner will log onto a forum to tell everyone how good their car is , hence it seems they all have problems if you read forums.
Imho its a small minority of cars that have failed engines .
Guess im gonna get flaimed now lol
