996 tt turbo replacement
Discussion
Guys,
I unfortunately had a turbo break, i think due to age, corrosion and the botched job someone had tried to fix!! Both the dealer, a specialised sports car dealership in Dorset, and Porsche main dealer missed this, despite two health checks and a main service!
And to cap it all the warranty on the car just lapsed - sods law!
Anyway I have decided to undertake the work myself and source parts (Genuine) from Ebay etc.. (Nearly new exhaust system £300 and two almost new turbos for £500 - saving over £5k on the dealer quoted prices).
I have removed the exhaust system back to the turbos and loosened the manifold, but have some seriously corroded oil lines feeding the turbos. Has anyone got any ideas or experience removing these? My first thought is cut them off as the end nuts are, in some case, just falling to pieces - if i took this route how difficult is it to install new lines?
I have to say its been great to get under the skin of these things, I have a better appreciation of how they are put together, not all great BTW!! But at least as the owner I can replace anything else that require it along the way - something in my experience a third party won't.

From what I understand, the oil lines across the top of the motor are a bit difficult to change even when done on a ramp.
I trusted the guys at 9E to sort my replacement turbo's out, along with all the oil feed/return anciliaries, to prevent any risk of recurrence of the same type of issue.
If you speak to the guys there, who are extremely knowledgeable and friendly, you might save a lot of time and effort and they could also quote you prices against E-bay. How you warrant something as 'genuine' off e-bay, I'm not sure!
They also warrant their turbo's longer than anyone else AFAIK.
Good luck.

Save yourself the hassle now you have the parts and get a specialist to replace all the parts under there with aerospace quality ancillaries such as bolts, lines etc. Its a design fault on the 996 t and if the car is a keeper you may as well do it properly. Only say use a specialist as I fear you will have to cut lots of bolts etc off due to corrosion which they all suffer if driven as intended. You'll need to check other things like waste gates, diverter valves etc too, hoses for no leaks and much better an indie like nine excellence or JZM do it for you properly.
Have replied to your email, only just saw this.
Re advice to see a specialist, with all due respect, if you can do this yourself then do it yourself.
My car has been at specialists (none of the above mentioned for clarity's sake, but well known all the same) and I could only deduce that they were very good at racking up massive bills for the previous owner, and bodging things. And overlooking others.
What you want to do is fiddly but no biggie, as I have explained in my mail.
Just remembered, you also need turbo sealing rings (gaskets, look like metal o-rings) there are two that will need replacing per turbo in different sizes.
And check condition of bumper heat shields they generally go soft after a while and start tearing away from the securing screws. Recommend removing the rear one (generally fine condition and very easy to remove) makes fitting new side ones far easier.
