How does it end?

no need to fear, we sell and service the most cayennes in the world. and to date we have done 2 v6s engine and 1 v8 engine and one of the v6s had no oil in it. Cayeen engines have been bullit proof, no need to start 400 threads about cayenne engine failure

Yes, but 'rings happen'.....not very often on a Zuffenhausen motor, but they do, especially if you are losing/burning oil.

Check on www.renntech.org, I think you need to register to see the list and if you're a contributing member you can see and read complete TSB's.
I don't know the issue completely off hand but there is a TSB on the rings.

For those who need insurance and are racers, this guy is the best http://www.dysonanalysis.com/

Will give you a complete oil report and will give you the scoop on the health of your motor + advice all on spread sheet.
A lot of professionals in racing and oil industry use him, super cool guy. Something like $50, just have your dealer fill the container midway thru the drain cycle when the oil is "hot"<(Important) and send it in.

I would do an analysis if you are knocking bad or blowing major smoke.

Hey, where did everybody go......oh, out into the garage to check VIN #'s......

Seal, ring.... eh, what the difference.

First there is one, then there are more... typically with only a few posts under their belt. Its the naked ones demanding new (errr..re manufactured) engines that really put up a stink.

the rings are typically put on with an automatic insertion machine. one of the first problems with these machines was operators loading the rings in the cassette upside down. the two solutions to this (supposed to be used in combo) were obvious markings from the supplier and machine vision technology to check the bevel direction on the rings once they were inserted. the cassettes typically held enough rings to do 50-100 pistons.

from the sound of this, they ran for a while without the cameras and it bit them on the ***. (this is pure speculation based on the technologies i know for this process. perhaps they are using kebler elfs instead) the equivocation in the TSB would be because some of the rings got loaded right, some of them wrong. this, by the way, is exactly the same problem i had on my audi. nice to know german production methods haven't moved forward in the last 10 years....

Thanks guys. Just my luck. I blew the engine on my 4Runner a few years back.

no real warning signs other then the ticking sound coing from the engine. no oil consumption.

Ok, so what part of the VIN is unique, is it after the P, or after the LA. Because my VIN ends in LA60895.

the last four digits are the serial number
