I think you should embrace improvement and get the car sorted out. Weissach is quite new. They’re probably great, but personally I’d have my car trailered to Litchfield for this job if I was you.

Porsche won’t come up with a solution for this I suspect, but the independent sector will.

I spoke with Litchfield this week. They dont' have a proper fix for it at all, they are making a manifold but nothing turbo related at all. I wish they would do though it would give so much peace of mind.

They said reasons that cause it:
Seal Gap on the turbo failing
Exposed turbos being near to the ground
OIl return line clogging up
Back pressure from the exhaust.

But I think in a majority of cases it's the oil return lines. They have a oil catch can which can help but doesn't fully resolve it

I've finally got my car back after 3 months this weekend. Drives much better than I previously remember! Does anybody know what is involved in a 111 point check and getting a warranty put back onto it & the costs involved?

Also if anyone is interested the link below sends you to the Service Bulletin & repair method by Porsche OPC's for this issue:

Seems like yet another engine issue plaguing another generation of 911...

I would agree, and I think the same issue might plague the 992 as well as I've been told of a few failures but being newer and lower mileage haven't cropped up as much.

All ok if you pay for the warranty though...

Looks like 997.2 and 991.1 are the sweet spot for reliability.

Yes sounds that way from a cost perspective, but interested to understand how long the car is off the road for to get it repaired, and do Porsche always provide a replacement car in those circumstances?

[PetrolTed]

Mine had the pipes done but not the turbos.

They had the car 2-3 weeks and supplied a Macan.

[Sukh13]

All for the low price of £1k per year and having to keep servicing the car at OPC prices (for all practical purposes)....

If you don’t count high pressure fuel pumps and engine mounts.

HPFP a 991 issue or only 997?

Glad you've got the car back on the road. You can put it behind you now and enjoy it. I've got hold of the Vektor performance oil/air separator catch can and I'm going to have it fitted this week along with the annual maintenance list planned. It should make the oil line less likely to clog up and my exhaust definitely has much less back pressure than the OEM set up. Any 911 with turbos can have issues with seals and being exposed, so always potentially vulnerable. I'm having a full clean up and lanoguard as well, so that should help with the protection issue.

My independent was waiting for one for a 997 (.2?) when my 991 needed one. They were on back order. Lumpy tick over is the sign. Plenty of comment on the net.

[Sukh13]

Is there a proven method to solve the turbo issues? The oil catch cans from Litchfield appear to be half the solution, but the turbos etc still sit exposed to the elements?

I wonder if winter salt as a rot accelerator is less of an issue on the Continent ?

When I had my GT4 tuned by Jens Ehressman in Dusseldorf he was surprised at how much more corrosion there was on the fittings of my car than he saw on vehicles used more locally ... ??

The problem I guess is cooling vs. being open to the elements ...

The amount of salt on our roads is absolutely ridiculous….I live in Bucks…they have 50 gritters that go out !!! Imagine if they spent even 20% of that budget on pot hole repairs. Winter tyres and no salt on the roads…we all know what would be better for the environment.

From my experience, the 111 point check is something you can ask any OPC to carry out on a car that fits the criteria of age, mileage, etc.
Whether it's a fixed price across the board or not you'll have to find out, but at Stratstone Bolton it's £216 inc VAT. You'll receive a report with either traffic lights for condition, or boxes with a more simple 'go/no-go'. It's quite comprehensive but really only a necessity to allow for warranty extension. I suspect a good indy would do something far more comprehensive if you could find someone to do it.

Ugh - I am glad I discovered this thread. I had narrowed down my 911 buying choice to a 991.2 GTS.

Back to the drawing board.

They are absolutely awesome cars but you just need the Porsche OPC warranty. For an update to the Forum I started. I got the car back after 2-3 months, had an issue with a gearbox connection so it was trailered again and then a month ago a coil pack failed. It sat on my drive for 3 weeks & It's been back at the garage for 2 weeks for all new 6x coils & sparks so I've been without another month or more! The coils have corroded inside and a new screw insert has had to be done but there is still issues regarding misfiring. Hoping to collect this week. Not sure if this is mileage related or what but I'm pretty sure my GTS must be one of the highest mileages in the country as I and previous owners have basically driven daily.

I think I will possibly be selling mine when I get it repaired and once I'm sure it's working properly after a fair few miles. It's a GT Silver Metallic with the very rare manual box. I've spent around £16k since February having purchase the car for £72k last May from a little known dealership in Bishops Stortford.. Not sure if anyone else has dealt with them specialists in Porsche? Its sad as I planned having bought high mileage to use the car for everything including trips down to Portugal and all the countries along the way.

As I said on my previous posts I'm shocked with the complications and build quality of Porsche as I previously loved them (one having saved my life) but going by mine at 50k miles - I feel like the best way to go with them is to buy one from a Porsche OPC (which is under 1-2 years old if you plan to keep for a couple of years) or with warranty - I wouldn't sway away from the 991.2 GTS as I dont' believe its any worse than any 992 generation. Had I known I would have had to spend massively on maintenance I would have just gone for the 997 GT3!

As per my previous comment I've had massive issues with coil packs failing and now they are apparently corroded so they need a thread repair. One had failed after driving through heavy rain but clearly they were bad before. So I would watch out of for these issues as well with yours or speak to Weissach as I'm sure they have gained a lot of expertise after dealing with mine. How is the Vekor catch can with your car? Out of interest after my car being at Weissach they are able to offer a comprehensive warranty the same as Porsche OPC's but clearly you need to be in Cheshire or local to the county.
What guys are you using for your lanoguard? I'm thinking that might be a good option for me and also if I've done it for future owners of the car.
