Back after 8 yrs with 997 woes

My first post in 8 or so years since selling an x50 turbo and the missus 986S.

Sold up due to a move overseas to Vancouver BC for her work, have been here ever since.

After a few initial months of arriving without Pork in our lives we get into a 993 C4 cab for me and a 987S for her, the 987 was later traded for a Cayenne turbo which was then traded in for RR sport supercharged. A move of apartment buildings with limited parking forced me to sell the 993 a few yrs on, made $25k on what I'd paid which was a first for me and cars. Another move and the underground parking was plentiful and although the Range was fast and comfy and brilliant on snow tires I was really yearning for something more involving, so traded RR sport for a 2014 Nissan GT-R black series.

Loved it, great car and on par with the 996 turbo x50 with regards performance. Missus wanted something older to park up at work all day where spaces were tight and after a week of her commuting in the Nissan we picked up a pin dent on the rear quarter courtesy of a fellow car park user.. that seals it, too nice for daily commute.

We found a nice little 2006 Slk55 amg in white with only 16000 miles from new for a great price offa private seller. Both cars were amazing and we ran them for a couple of years...Until. I spotted a Nismo GTR in pearl white and as i was enjoying the standard car so much did a deal and traded up .. the Nismo is EPIC

Last year around Xmas the City had a fair bit of snow and the Slk55 with all season tires was dangerous on the road, I had to rescue the missus after she got stranded and run her to and fro work in our minivan on snow tires for a couple of weeks,

So recently the hunt started for another Porsche for her to commute in and us to use at weekends, the Nismo is low miles and I don't want to pile too many miles on, I loved the power of the little Amg but always felt like a hairdresser in it

So, she doesn't like 996 interiors any more, can't afford a 997 turbo or most of the 997.2s that are floating about here on the west coast, fancies a 4 wheel drive for the snow but needs automatic for her commute in traffic

997.1 C4S tiptronic Cab is what we start hunting for, typically we see no C4S at all with a tip after months and months of searching.

All of a sudden a C2S cab tip 997.1 2005 appears online, we figure with a set of winter tires she'll be ok without 4 wheel drive and begin to enquire with selling dealership, the price is good in comparison to asking prices here in Vancouver and so after plenty of pics and videos being supplied we go check the car out, salesman is great and very chilled
Gives us the car for 2 hours alone and off we go on a test run
I can feel it needs the usual suspension refresh, but all gauges say the right things and a cold start at the dealership that I requested showed zero smoke on startup.. engine pulls nice and the car is extremely well optioned.

Return to dealership and leave on the basis that we'd think about it overnight and do some digging and perhaps leave a deposit over the phone based on checks on the vehicle. Very very rarely here in North America it seems does anybody keep receipts, stamp service books or keep records etc, you do a Carfax and that's it.
There was one computer print out list of work the car had had done left in the glovebox by the previous owner who had traded in the 997.

The car has had a lot of work according to what I can see
Most namely new cylinder sleeves x6, pistons, bearings, lifters.. etc
The garage named beside the work was a garage I'd heard of, a pretty reputable Indy Porsche outfit, seems the car had a rebuild in 2015

So I call the garage and the owner although a little vague remembers the car had a failed radiator and went in to Porsche who replaced the rad and later did lifters as the engine was ticking, turns out as you can probably guess, the engine had bore score due to overheating. So this Indy then said he went through the engine and did a full steel liner rebuild but can't provide invoice details due to data protection etc, assures me In a condescending manner that borescore would never be an issue going forward with these liners.

I'm feeling quite good about this news, so hash out a deal with the selling dealership based on a full compression test and bore scope at the local Porsche dealership at my cost, a few days later car goes in to Porsche Centre and I get a phone call telling me that all is good with compression, less than 10 percent across all 6 cylinders and also that the bore scope was fine, just 2 very fine lines in cylinder 1 that had to be super magnified to see and that looked like honing marks, they also noted the engine had been re sleeved which corroborated with my paperwork and the call to the Indy garage who did the work. I was then asked whether I wanted a new set of plugs put back in as it made sense whilst the old were already out, and that also plugs 1 and 3 were oil fouled although this was normal if they had not been changed for 3 or 4 years, I agreed and asked, "so it's all good then engine wise? " Yes it's a good one, enjoy it was the Porsche service managers reply

Had Porsche then do a brake fluid flush and an oil service. picked the car up a few days later and headed back to Vancouver, took a long route covering around 190 odd miles home to give the car a good run, the car ran well apart from a brief flash and beep from the engine management light, on for maybe 3 secs and never returned.

Get home park up and stand around checking alls well and nothing's hanging off when I notice black soot around the bumper and 123 bank exhaust is looking very sooty.. here we go 😟. I Wait an hr or so and check oil level on dash to find car is at minimum after having an oil service less than 200 miles ago, it swallows just under a litre to get back to full line so that's 1 litre of oil consumed in under 200 miles and black soot all over the rear right tailpipes, great .

Immediately get on to the selling dealer via email, it's agreed we will not drive the car until I get it checked out by a local specialist of which there are a few in Vancouver, soonest appointment I can get is for Mon 16 Nov, 9 days time. So left her parked up for over a week and this Monday just passed I fired her up for the 2 km drive to the local specialist. Huge plume of grey smoke out of sooty tailpipe and splatters of oil on parkade floor, drove her in and they pulled bank 1 plugs to find 1 and 3 heavily oil fouled and excessive scoring all the way around cylinder 3 😳 Pics supplied to me..

So currently im waiting for the selling dealer to collect the car and take it back on a flatbed to Porsche to check for what they didn't see 200 miles ago.
From the pics I've supplied to them of the borescope of cylinder 3 they're saying it doesn't look like anything out of the ordinary for a car of this age and mileage but will have Porsche do a leakdown test and investigate further

I've stated I want a refund or repair but doubt they'll repair properly as I've heard ball park figures of $25-28k, that's 90 percent what I paid for the car.

So we may be back on the forum in a 997 depending on outcomes.. but I'm convinced the engines is toast

I'm sure this post is way too long but it's been a busy return to Porsche

On the upside, I've already fallen in love with the drive of the 997 and even enjoyed the tiptronic experience

I will update as I move forward for anyone interested

Until next time

Hi

What a great post up until the awful bit. My heart goes out to you. How careful do you have to be? You did everything right and still get a result like this. I'm pretty much lost for words.

I really hope it has a happy (refund) ending!

All the best and fingers crossed

Berni
 
Thanks Berni, can't believe Porsche main dealer missed it, the fouled plugs should have been a clear indication worthy of follow up
From the info I have the car has only done 12k miles since it's rebuild and has fallen prey for the 2nd time in its life :dont know:
 
It seems.like you're not going to be out of pocket which is a relief.

It's a long post so i might have missed something but as far as i can tell ...

You had a borescope check done and they said it was fine ...

Ok so no scoring ..

They then said new plugs as two of them are oil fouled ???

Erm .. no .. they don't oil foul if they havent been changed for 3-4 years .. service interval is 4 years and if what they are saying is correct .. it isn't .. then why where not ALL of the plugs oil fouled ?

There is evidence there but they missed it .

You drove 190 miles and it was then found you have excessive bore score ..

That single picture whilst it has marks is not what i would call major .. it certainly would not account for 1.5 litres of lost oil in that milage .

Perhaps one of the other cylinders was a lot worse ?

If the scope was done properly then my gut feeling is there's something else going on there .. more than one way for oil to get into a cylinder .. piston rings and valve guides spring to mind with piston rings being the most obvious ...

perhaps from the rebuild .
 
The car was collected this morning and I believe they are going to start with a leak down test. Will keep this thread updated

The selling dealer seems to feel the level scoring in the pics are normal and indicative of a car at this age and mileage

Whilst I've seen worse bore score examples online, bear in mind these are steel sleeves and would be harder than original alloy ones so may scar differently . Bore score nonetheless

Oil consumption was 0.8 of a litre after 190 miles
 
So after having the car collected with a flat bed over 10 days ago I still have no news, have emailed and have been told to expect a report tomorrow, porsches top tech is finishing off a big timing cover job apparently and wil, get to the borescored oil swigger next.

Hoping for a rebuild or new bottom end, have read that Hartech are licensing their name to a Porsche Indy in Calgary who are applying Hartechs rebuild process, this maybe a route to consider should I be offered options outside of a Porsche bottom end

Was so nice to be back in a Porsche after many years, even if only for a day

Will update as and when
 
A sad situation indeed, you had a right to expect much better. Keeping my fingers crossed that things will eventually work out as well as seems reasonable.. :thumb:
 
If you get the chance I would ditch the steel liners and go with what Hartech produce, I have seen a nickasil bore when it has large particles being rubbed up and down the bore and there is hardly any damage to the surface, a lockasil bore has totally had it with the same debris.

With how much oil you have lost (I say lost and not burnt) I would assume the liner had shifted to allow a decent gap in that time. Have they not mentioned anything along those lines?

I would have steered clear of any car with steel liners in the first instance so make sure you don't get a like for like repair, you need it upgrading from steel, which as you have found out can be a ticking time bomb?
 
Steel liners, yes I've read but only after this situation arose, up until that point I was comfortable with the fact the car had been rebuilt recently and with a Porsche dealer bore scope where they actually noted the re sleeve to me over the phone I was sure I was buying something that was going to be trouble free, this really is an unbelievable situation.

I cant see Porsche repairing with anything but Oe, and as the engine has steel liners they would have to do the full 6, I would accept a new factory bottom end even with the standard lokasil as this would surely give me a certain amount of reliability going forward

Should I get offered options I may opt to pay for a Hartech bottom end and have Porsche strip and rebuild, this would keep the price down and only cost me another 6-8k CAD, I can't see Porsche putting out anything but oe from their workshop though so we will have to see

It will be an interesting end to the week and I shall update

Appreciate responses
 
A new bottom end is fine if Porsche are doing this but if the selling dealer is to pay for the repair I would upgrade from standard if they allow that, I wouldn't be putting my own hand in my pocket for this though?
I know OPC in the UK don't usually go with aftermarket solutions but I do know that Hartech have sent engines abroad for years to various countries OPC's.
 
So the 997 was finally looked at by Porsche centre Victoria on Vancouver island, third time around they have acknowledged the damaged cylinder walls

The dealership manager for alfa, Maserati, fiat where we bought the car phoned to confirm what I already new.

He asked if I'd still see value in the car if he rebuilt the engine at his cost of $24000, otherwise we could trade in on something else in stock

Looks like he's gonna be upstanding. I said if it were a warranted rebuild I'd be interested in having the car back, I think Porsche will do it as they're part of the same dealer group, and whilst it took them 3 bites to notice the bore score I would imagine any engine work would be guaranteed

The dealer manger is meeting with his senior tomorrow at 1pm to discuss the options and will call me later in the afternoon, he has also offered a courtesy car for the duration of the rebuild

Could be a silver lining and a happy ending

I'll keep this updated
 
I think it depends who is doing the rebuild. For example here Hartech in UK I hear can rebuild 3.8 to 4.0 better than new. I think you are in a nice position to have that car future proofed. Shame its not a 4S with all that snow over there is only thing I would say. If you can stretch to PDK and 4S this would be optimum or wait for tip 4S like you wanted, I have a turbo and main reason i do not swap is its so useable and confidence inspiring in bad weather awd make it as effective as an SUV cross country 8)
