If it was a major issue wouldn't Porsche fix without a warranty?

What causes them?

Do you need to worry if your buying an 07 + 997?

Is it a problem on all 997's or just 1 in 100?

What's fact rather than fiction!

Buy a 997, get a good warranty (it's an expensive complicated car and needs one for any number of reasons)

Drive it and enjoy it, fill it up again with go faster juice and repeat the process frequently.

Don't worry if there's a problem, you have a warranty to cover mechanical problems.

End of thread.

Do a search on this - Baz Hartech has given lots of details on these issues - also plenty of facts on Hartech's web site.

Have a read of the Hartech site and the sticky in here. Then see if you have any remaining questions. I'd say buy OPC car with their warranty.

Be prepared to get nothing out of PGB, it will save disappointment further down the line.

DFI engined (08 and later) cars apparently don't suffer from these woes.

08 and earlier have relatively small rate of incidence of engine failure due to RMS/IMS failure and bore scoring/cylinder deformation due to cooling issues.

997 GT2/3/RS and Turbo cars use a GT1 derived engine which is reputedly more robust. There are again, small rate of incidence events of catastrophic coolant leakage due to coolant piped being glued/bonded to the engine block rather than alternative, more robust methods which I know nothing about so won't offer advice on the matter. You'll find other threads on here discussing thoat.

Usual caveat emptor: Your mileage may vary; there are many more knowlegeable on here than I on the subject.

As above, want an early car? Buy a warranty for peace of mind, then get on with enjoying one of the best drivers' cars available.

Has the DFI engine actually fixed these issues, or are theses cars simply too new to form any meaningful engine failure statistics? I guess time will tell.

They havent 'fixed' the issues as such, it is a toally new engine. If they have repeated the inherent design faults, it would be incredibly stupid.

In terms of the performance so far of the new engine, 3 years on, it would seem to be looking good, unless anyone else on here has information proving otherwise?

I have heard no instances of the suggested coking up risks.

So a C4S registered in 2008 will be ok?
or actually, are C4S engines all ok to start with??

No, it has to be a DFI, which was introduced sometime in 2008 in the Gen 2 car (Stupid Audi side lights).

C4S same engine in either case.
