Hi Everyone,

Just curious/wondering if any of you (or know of anyone) have had a major engine problem/failure/bore scoring with a Gen 2 997?

I'am not new to Porsche, but currently own a gen 2 997. I am still unsure whether to extend the OPC warranty. I'am leaning not to do it. I know these engines are much more robust, have better cooling & are DFI etc, etc.But Hartech feel it is only a matter of time that we'll see some engine failures with these engines (possibly due to the Alusil construction) - but probably in much fewer numbers than Gen 1 cars.

I think the bodywork will outlast the 964/993 style without major expensive work as well - so - I would be less certain about my conclusion and feel it is more likely that future owners will see the sense in having an engine rebuilt before there is a failure and in the process result in two levels of prices.

Very true in many ways. The piece above that I have quoted is true if anyone was in the market for say a 996 NA, Gen 1 997 NA or even older 911s where there is known to be a problem. Take your point - it would be worth sorting the engine issues out. But with a Gen 2 997, 991s where there is little evidence (yet) of what the potential problems are etc it is a big ask for someone to get major engine rebuild work done. Surely it is too early to tell?

A thicker oil, lower coolant temperature (LTT), avoiding hard acceleration from cold and after being stationary when hot will all help extend cylinder life.

Baz - what oil would you recommend for a 997 Gen 2 NA?
