997.1 Purchase
Discussion
Hello,
About to pull the trigger on a 997.1 Carrera C4S 55 plate which has done 40k miles.
The question is that i cannot make my mind up if its worth changing the IMS bearing now and also to fit low temp thermostat to the car?
I will be having a PPI, including bore scope just before purchase.
Thank you,
Phil

Spend the money and do the work and drive your new toy with peace of mind. If you don't, although it will be probably be fine you will end up either not fully enjoying the car due to worry or potentially selling it prematurely as you will be thinking about it too much. If you were not a PHer and didn't read these forums, then ignorance may well be bliss, but we both know that isn't really the case for you as you've asked the question!
Do have a look at your engine number and check with this chart
If you've got the later, bigger bearing built in cars after feb/mar 2005, you're all good. In fact you can't change the IMS without opening the engine.

Regarding the low thermostat, the opinions seem to differ. There is a powerful lobby who highly advocate for it and then there are others who advocate against it.
I have left the original thermostat, as Porsche has conceived it, in place. I don't, and can't due to knowing it better, advice for either practice tough.
Oh, and get that C4S bought
And due post pictures!!

Sorry Phil you did say about the bore test at the start.Thanks,

I would get the uprgraded ims bearing done and a nice new clutch at the same time meaning you will feel some kind off betterment and will help with value later.
Copied thread from Hartech ( the most trusted Porsche engine builders out there) regarding low temp thermostat

What kind of warranty is it going forward?
Does it cover bore scoring and does it have a decent claim limit £7.5k - £10k ideally?

Is it eligible for Porsche warranty? If so I'd do nothing and warranty it.About to pull the trigger on a 997.1 Carrera C4S 55 plate which has done 40k miles.

It will be on the spec sticker in the service book if it is the original.
Example from google
Is the car advertised or someone you know and assume it is a private sale?
Just be wary that some aftermarket warranties won't cover cars over 12 years old.
Personally I would only buy from a Porsche specialist that are experts in the product and have warranties that cover things like bore scoring and ims failures.
Some will allow you to get a decent claim limit so will cover the cost of a rebuild.

No, the engine number is not on that sticker. It is on the engine itself.
Have a look at the oil sump on the left side (passenger side on RHD).
Pic from google. It may not be as clearly is this. Take a wet towel, some WD40 or brake cleaner if necessary. Best to take a photograph and try to read it from the screen.
