Hi

I bought the car from a garage last December. Full main Porsche dealer service history and low mileage at 40K.

The day after getting it home I filled it with fuel and did the elec oil check.
None of the boxes were filled in. I tried a few times on level ground and put 400ml of oil in. long story short it took 1.6L to bring it up to the full level.

reported my concerns to the garage and told them i would be monitoring to see if it was using oil and how quickly.
Took several weeks to cover miles due to work but from that full point it used a further 2.8L of oil in less than 2K miles. Both exhaust tips were completely black regardless of driving distance or short hops.

There was a VERY slight noise from the engine but nothing to raise suspicions. Reported my findings to the garage and had it checked by a Porsche specialist garage. Report back showed notable bore scoring on 3 and 6 + some mottling/degradation of the cylinder wall lining. There was also a small area on 6 or 3 that had a heat spot - purple blue colour.

Upshot is that the garage are paying for the repair (Phew) and looks like 2 new crankcases, pistons, associated parts and labour bill = £10K ouch.

Thats All I know at this point. Excpet to say that all that BS when a car is using a lot of oil - well its going somewhere and in my case it was seeping past the piston rings where it was scored.

In closing every credible source I have spoken with has said that this is 'rare' in Gen2 997s I am just unlucky!!

3.6 or 3.8 engine?

Hi
Sorry for late reply, the car is a 3.8S

Hi

When I confirmed the problem I did the usual trawl to see if there were others and how they got it sorted, cost etc.
I only managed t speak to two other genuine people that had the problem.

I would appear that at this point in time the Gen2 is a very robust better engine, there are always going to be the odd few engines that have problems.
I guess I was just unlucky.

Thanks Glen. Do you recall if the other cars affected were the 3.6 or 3.8s?? Mike.

I have just been through all the posts on this poll. It seems like almost all those who report problems are S models. So am I right in assuming that this problem is almost exclusively 3.8 engines?

would like to hear about this as well

Found this on Revolution Porsche, a British website. It confirms my thought that the issue is mostly 3.8 engines:
"Another issue you are likely to have read about on Porsche forums is bore scoring, which can also lead to engine failure. The extent of the problem has been exaggerated and in reality it has only affected a very small proportion of 997s; although that will be of little consolation to you if it happens to your car and you are left with a repair bill for thousands.
Bore scoring isn’t a problem for the direct fuel injection engines of the second generation Porsche 997 or for the first generation Turbos and GT models. With the first generation flat-six engines, it is most likely to occur on the 3.8 but is rare on the 3.6.
The key symptoms to look for are a blackened nearside exhaust tip or a tapping noise at idle. If you spot either of these, or even if you don’t and you just want reassurance that a major problem is not imminent, arrange for a borescope inspection before agreeing to buy."

Hi,
Cautious that I do not get burned at the stake as a heretic of Gen2 997 Porsche's.

They were 3.8S versions. That in itself is not a suspect statistic as the 3.8S outsold the 3.6 vanilla by a ratio of 3 to 1.
Additionally, the numbers are small compared to other models and issues.

I did find out that my car was a launch showroom model for Porsche Exeter UK. That is why it probably has so many nice goodies on it.
However, one has to consider the likelihood that as a launch model and a car that was used to show potential customers it probably had no break-in at all?

Guess I will know within the next week if the dealership is going to try and stuff me on the repair.

Gen2s are great cars, with my degree in hindsight despite buying it from a main dealership with a 12 month warranty I should have had an indie PPI it. If I had I would have walked away.

Moral is - check it before you buy it regardless of where you buy it from to ensure buyers glee not buyers remorse.

Hello all, and good day.

my 06 C2 started ticking before 90Km, and now it is louder more like a TOK 118Km, last week while driving the yellow CEL light came on then started blinking. drove home about 1km away.

codes read, P0300, P0310, P0305, P0306 all misfires, we changed all the plugs, fresh oil, oil and air filter then reset with durametric. started and now running no code.

we looked at all the plugs and CY#6 serious fouled with only 3883km, and all the other were fine.

the air filter was dirty with only around 50Km on it. the best is still no O2 sensor code, or any code after above noted service. this was the first time with blinking yellow CEL light. car burns little oil as use Liqui Moly 10W60 year round driver.

we will advise when this C2 goes off a cliff. planning a 3.8 litre rebuild with sleeves. car runs well drives nice but that sweet TOKTOKTOK, what looks i get on road with people shaking there heads.

PCNA might want to give me a new engine as i am sure buyer will never consider buying a porsche ever after hearing my roaming beast..lol!

A 3.6? Say it ain't so!

Render

how much did it cost?

MessiRabbit

2006 C2S, 6spd, 60k miles. car is all stock, maintenance records are spoty at best. but over rev is very clean, 0 in the 4-6.
Car spent 06-08 in South Carolina, then 2008 to present in the Northern VA/DC area.

Edit: Local shop gave it clean bill of health!

AWDGuy

3.6 is also affected. Honestly, not to fear monger here, but scored cylinders will probably affect more porsches than bad IMSB's.
