My 996 C4S is currently undergoing a full rebuild after scoring found on Cylinder 4 (quite bad with metal found in the oil filter) and partial scoring on Cylinder 5. Rebuild by local (to me) engine rebuilder who I trust.
Symptoms present which led me to this issue was significant oil burning and a loud tapping noise. Should be better than new once complete, but won't get the car back for a bit as the guy has a few others in the queue

No idea, I did start a thread about it as I'd only just purchased the car and I noticed it from driving just a few hundred miles. It was an 'intermittent' noise (i.e. I wasn't really listening for it at first) so not obvious on the test drive, and the oil usage only became obvious when I saw the smoke and saw the gauge dropping.
Car is on 73,500 miles and I only did 250 of those.
I'll update the thread once the car is back (or at least when I have a confirmed return date), but I am having a full 6 cylinder rebuild at minimal cost to myself.

And they said that the 996/997.1 was a reliable engine and the problems were all internet 'hearsay'. This thread proves that they certainly aren't, despite the rose tinted spectacle wearers trying to persuade us all otherwise.
Yes I've owned one and yes it needed a rebuild 996.2 (@ 85k miles)
My friend had one and yes it needed a rebuild 996C4S (@ 22K miles)
His friend had one and yes it needed a rebuild 997.1 (@ 70K miles)
Come to think of it I literally can not name someone who I know who's had one which didn't need major engine work.

Hi I get my 997 C2S 3.8 next week, mine had 63k miles and went from running fine to tapping within 1000 miles of purchase from a dodgy dealer on ebay that lied and claimed he wasn't a dealer, repair bill is over 60% of what i paid for the car.
I should have cut my loss and broken the car but i've offset some of the cost by the increase in value of my 964 so purchasing any 997 seems to be a gamble.
For the record the IMS was the smaller item and was OK but i've upgraded to the later larger bearing and hope the car will last another 100K

I bought a 2003 4s tip, 1 owner and 45k miles full opc history, before purchase had a PPI which inc a borescope which was all fine, needed rear brake pipes as heavily corroded so an engine out job, while out the indie specialist split the gearbox to check the IMS bearing and by turning the engine by hand they could feel the bearing feeling lumpy they advise two options - replace just the bearing with the ceramic LN bearing or replace with Porsche upgraded bearing but would be a full engine strip and rebuild.
I chose the LN bearing as it is a 2nd car and prob 2-3k miles a year and looking at keeping the car for a few years.
All running very well.

I stripped a 996 engine down today that came in due to sounding rough when warmed up.
It turns out that it was actually running remarkably well considering the current state of the engine.
A valve seat has dropped out and got chewed up and spat out, damaging the piston along the way.
Also has scored bores to bank 1 which less common as it's normally bank 2.
I see lots of Porsches and rebuild LOTS of engines and I can honestly say the most common repair to date has to be bore scoring. I've done a few rebuilds due to IMS failures but they are few and far between. Never personally seen a D chunk failure!

Just seen as its on this topic, of engine rebulild
thinking of venturing into the world of porche owenership,
Considering a 997 gen 1 as its probably the best I can afford comfortably.... Without too much debt,
https://www.usedcarsni.com/2007-Porsche-911-CARRER...
Car can be see above,
anyway question I have is,
Does mileage have any relevance towards the bore scoring issue ?
for example if the engine gets to 80k miles can we feel safe it wont happen or can it just happen at any time ?
Will of course get a pre-inspection done but just wondering is the fault inherent in all the engines that haven't been taken care of or just some that slipped through the factory with the un-noticed flaw
Thanks in advance

I noticed earlier in this thread the RMS leak was mentioned. My 997.1 3.6 has a RMS leak but my indie says it’s nothing to worry about & that a couple of drips spread and make it look a lot worse than it is. When do I worry about it & is it engine out to fix. What is the likely cost approx.?
is that true? As you can tell.. I’m not a mechanic.AwfulAutoMan said:

I'm in NI and was in a similar boat. Have you considered the Cayman S as a firsr step into Porsche ownership? It's what I've done.
Nice gen 2 987's are well within your budget - like this potentially good example if you don't mind a flight to England.

Going for a test drive in it tomorrow, be glad and appreciative to hear your opinion of it or anything that stood out.
Yeah I thought about the cayman S but it's the 911 that I of course really want and generally its going to be a second car for myself mostly not a daily driver, only when the misses wants the daily for herself for the day.
Thanks for the input
