Next after those people will come the cars that we have carried out our retrofit services for using the current LN bearing.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Has anyone had a similar problem?. 2002 996 Carerra C4 (3.6), 38k miles. Took to my local independent for MOT and concern over oily smoke sometimes on start up. Just been told the cylinder lining in cylinder 6 and 5 has signs of scratching and needs a major rebuild. Cost of upwards of £5k. Is this common??? Any alternative solutions to a rebuild?.

POST 2Original post

Sadly it does appear so. Check out the Hartech website as they're as one of the best in understanding/repairing the problems by all accounts.

POST 3Original post

Yes pretty common I'm afraid. Sad state of affairs when it happens to so many low millage cars. Shame on you Porsche. Even a Fiat Tipo would exceed. Not sure if I have much confidence in that company that got there Oil sticker put under the trunk either!.

POST 4Original post

Common problem, i suspect the widespead use of a generic 10W-40 or similar doesn't help, as soon as these cars are run in i'd go onto a synthetic xxW-50 with a bit of ZDDP, they use no oil so cat contamination is unlikely. bearing in mind i've been running an oil burning 928 GTS for 16 years and the cats weren't harmed. Hartech will fit a slightly lower temp thermostat too which helps maintain oil film strength. I sometimes wonder if oil advised by OPCs is more related to financial than mechanical considerations?

POST 5Original post

If it's "only" signs of scratching you're lucky in some way... ;-) Take it to Hartech for further assessment and recommendation, you could get away cheaper than 5K when there's no other damage occured.

POST 6Original post

If you want to frighten yourself witless, pick up a copy of 911 & Porsche World this month. There is a 9-page article about engine problems. No wonder the value of these cars has plummeted with scaremongering like that.

POST 7Original post

I've not read it, but do I take it that it's not good news for 996 owners?

POST 8Original post

Good news if you're in the market for a pre loved 996 though!

POST 10Original post

Interesting conversation I am looking at this from a different angle the 996 is now a class one car in the Porsche club championship. I have been thinking about building a race car on a limited budget so what I need is an early 996 with a blown engine ,this if we listen to the forums and magazines should be an easy task as there are so many cars out there with blown engines. Guess what I cannot find one Paul Seagrave

POST 12Original post

And just a bit more from Flat six "a new solution?" Quote: If the solution wasn't an improvement we wouldn't have worked since 2009 to perfect it. In time the Solution will be a retrofit kit that's just as easy to install as the current retrofit. Upon my return on Friday those who own my engines will receive an email unveiling the technology to them with their opportunity to upgrade their Flat 6 Innovations engine with the IMS Solution. Next after those people will come the cars that we have carried out our retrofit services for using the current LN bearing. After these we will then offer the Solution for install here at Flat 6 only for the first year or so, before starting to sell it to other shops and etc. we have not decided whether or not we will require installers to attend training before they are permitted to install the Solution. We approaching this with great care and until March 2011 we hadn't shared anything about it with anyone, anywhere. Currently at 5,500 mikes for the trip and the vitals for he engine are perfect. Hmmmmmmm whats new then? I guess we will have to wait and see!
