Researching the longevity of a 2004 S

 

my 2004 Ford Diesel truck has 230,000 and my 2005 Chevy Avalanche has 225,000. Good question, has any Porsche Cayenne on this forum made it that long on the original engine? plan on driving my Cayenne to at least that long, only time will tell

 

There have been a couple of Turbos on this forum that have exceeded 300k, but I don't know of any Ses that high.

 

My engine died and I have to option of buying a used one for a decent price (106K for $4640). Wondering if it's worth it and how life I can expect from it.

 

If this was me, I would find a way to rebuild what I have.

 

I have no idea what new or used Cayenne motors go for so I can't judge that price, but I would offer that you should factor in having it completely rebuilt and gone over with a fine tooth comb. It probably doesn't need anything major, but it's going to be much less hassle to find and fix things before it gets installed and then you'd have the piece of mind about knowing exactly what state it is in.

 

If your engine died then you have a good idea of longevity! LoL
But seriously I would get in contact with any of the forum sponsors that rebuild engines and get a price from them. More than likely you can have yours rebuilt bigger, better, faster than the price for a used unknown engine.

 

What caused the untimely death of the motor?

Since you asked, my CS has 158K miles and counting. History is 5K oil changes, lots of preventative maintenance, known problems addressed. Oh, and lives in a mild climate.

 

new north of 12K

 

Ken,

Do you own a Cayenne S? If so do you live in a colder climate? It's no secret the Cayenne S is prone to scored cylinders causing catastrophic engine damage. Apparently, Porsche did not get the piston to cylinder wall clearance correct which is causing so much damage. I would NEVER buy a used engine especially a used S engine. I wouldn't even buy a new engine from Porsche because in time the same thing will happen (scored cylinders). There is a vendor on here named Flat6 that apparently knows how to rebuild these engines to last. I personally have never done any business with him but he sounds legit and knowledgeable on this forum.

Unfortunately lately, Porsche's engine building prowess is at best laughable (IMS -911/boxster, RMS-911/boxster, scored cylinders-Cayenne/911. Lot's of their last generation cars are starting to show major issues as the miles are getting put on..

 

I bought the car used...and what looked like a great deal has turned into a horrible investment (wife takes pleasure in reminding me every day). I looked into the rebuilding option...most shops around me either can't do it and encourage me to go a different route due to the unforeseen challenges and/or price. I also looked into Flat6 and was impressed, but the charge close to what a brand new engine would cost (not financially smart). The person I bought the car from will buy the replacement engine and I just have to get it installed. As I mentioned earlier my good deal is now a not so much. I paid $13K for the CS with 62K on the clock. Engine locked up after 3 miles. Now have to spend $1500-2500 (prices I've quoted) to install a replacement.

 

You didn't mention what kind of replacement engine (new or used) that the seller was willing to buy? Props to the seller for willing to do this! If I were you I would dump the car after its fixed. The S engine is garbage.. Good luck!

 

Used engine...I was thinking about that too. I don't know... I really enjoy the car and have always wanted a Porshe. Will see how things play out.

 

Well, you have been warned if it happens again..

You must be feeling lucky?

 

Seriously, there aren't that many Ss around with the scoring problem. Yes, it does happen and yes, it is more frequent on Ss than turbos.
