Sorry I've been busy - but glad you take my opinions so seriously

Really, there's no need to apologise, your contribution wasn't missed

As for your opinions being taken seriously . . . .

[Orangecurry]

Not a Nissan fan then?

Any meaningful discussion of engine failure rate HAS to involve some proper number and some real hard facts backed up with real life evidence.

So on that note ....


total 993 production, 68,000
total 996 production, 176,000
total 997 production, 216,000


997 engine failures, one a week reported on the forums
996 engine failures, one a fortnight reported on the forums
993 engine failures, one a year reported on the forums



So even accounting for the build numbers, its plainly obvious that the 993 is far far more reliable

[Orangecurry]

But 993 owners can't use the internet, so you can't use stuff posted on forums either.

Has anyone here read this which IIRC covers Porsche engine failures?

[jackal]

993 owners invented the internet

[Orangecurry]

Have you filled that coffee-pot up yet?

Well if we're getting into semantics, what do you term a failure ?
An IMS failure on a 997 is a very different kettle of fish to a through bolt seal failure on a 993 . . . . .

Have a chat to some engine builders or any of the Indys that have been in business for many years. Catastrophic failures on 993s are relatively rare. Rebuilds are normally limited to the cylinder heads and are due to worn valve guides and the like.

Sure someone having a stir , as we have run a standard 993 engine in our GT2R without knowledge of its history although we used RSR cams and thus a top end rebuild , in the 24 hours last year as well as a 3 and 4 hour race this year with no issues. This included a few recorded visita to 8,200 RPM which were not ideal.
Air cooled Porsche engines bulletproof PERIOD.

[mollytherocker]

Hartech have a seperate workshop that sepcialises in rebuilding 996 & 997 engines.

Ring them up and ask how many they do a week!

Interesting. So would this influence the longevity of this particular engine?

Experience has taught me otherwise -sadly. But take the best bits from the air and water cooled engines and add them together as in the Mezger units and you do get bullet proof.

My Datsun GTR has now completed 15.5k miles without an engine failure despite the much higher power output. Porsche eat your heart out!

I did have to buy 4 new tyres the other day - only 1200gbp fitted though - its almost like Datsun ownership is becoming semi-affordable double whammy......haha

I am looking forward to new discs and pads already. Now that it will only cost 2.5k though - it will just devalue the car making it affordable for the Porsche-driving masses.... damn.

But seriously - engine failures are quite rare on the aircooleds - but rebuilds are not. There is a difference you know!

I rang them a few months back and they had around 22. Yes 22!!!!!!!!! 996/997's in for engine problems.

I think this was a total number that were being worked on and had been booked in to do work..

Put me right off buying a Porsche

Actually its your problem as you still have the old girl.I don,t!

[speedbird1000]

Turbo owners, you can relax knowing your engines are far more reliable....oh and powerful too....

[hunter 66]

Yes , they do not like those rev ranges , but in many years of racing Porsches ( all 964 and 993 era cars ) never a hint of an engine issue which is reassuring.

[Henry-F]

Me to. Well, other than a 993 engine which popped a rod through the crankcase as I turned into McLeans. To be fair it made it back to the pits under it's own steam so you can't grumble.
