New 997.1 tt owner - advice needed please

thanks demort. pm replied to also!
The leak was cleaned down with brake cleaner and it is definately coming from there with no signs of leaks from anywhere else, either above or below! But will go and have another check with them tomorrow.

Will have to speak to Statler or someone of that ilk and see if I can get it there for the required fix if needed because this garage doesn't have the Porsche timing tools and wouldnt be able to remove the chain tensioner as a result (and nor would I want them to).

Cheers
 
From the perspective of casual observer, I've enjoyed this thread. Appreciate it must be more emotive for the OP.

Hope it all sorts out, sounds promising so far.
 
Could be bargain of the century :worship:

He who dares indeed :grin: I'm either brave or stupid, or most likely both!!.

Lots of work done on the car, all coolant pipes at the front (the front pipes werent leaking but there was evidence of greenery on a few joints and they needed doing); the engine bay ones and the long ones have been done under warranty luckily in recent times so they are like new. Radiators are all new last year and so are aircon condensers Exhaust all sorted and turbo studs etc... Now the turbos are bolted up properly it has highlighted one of them has an exhaust gas leak between hot and coldside and you can hear/feel it losing boost when driving enthusiastically. :nooo:

So I am taking it home and going to get both turbos removed and rebuilt (hopefully) or a new pair. Upsetting :grin: but apparently a very common issue according to the turbo specialists i have spoken to on a lot of 997t's now, especially if they have seen uk roads in anything other than dry weather. (corrosion on the hot side casing that thins the cast to the point it starts blowing) Will update this once I have it back home with a few pictures of the ensuing work. I think it will be a total PITA getting the old ones off but it must be done and I have done much worse.!

Keep an eye out for the updates!! I am sure it will become more interesting as I near the finish line!
 
Sounds like you'll have a well sorted car by the time your done.

When you mentioned pipes looking 'greenish' didn't you mean 'pinkish' as you should have it filled with the pink/red coolant.

Have you def diagnosed the pressure leak as a duff turbo? There are lots of other places you can loose pressure, also if one of your actuators is not functioning correctly you can have the same issue. I had an issue with an actuator and a pipe blowing off from the turbo unit. If an actuator fails you tend to loose pressure back through the dormant turbo, you'll get barely .2 bar on the gauge and the car juts doesn't pull like it should.

Sorry, was late. By green I meant externally on one of the pipe joints (eg an old leak possibly), the coolant in the system is pink . On inspection the pipe joints were not in great condition. The coolant system has also now been vacuum tested and is totally airtight. There wasn't a leak on the front coolant pipes before, but I had them all replaced because the garage has done lots of these on 911's and it seemed like a better thing to do now than wait for problems down the line.

Its definately a duff turbo unfortunately. Now the exhaust is airtight it found the next weak link and you can see soot stains on the joint from exhaust housing and if you hold some paper next to the leak, it flaps from the leakage!! The other turbo has a micro soot stain but no leakage, but I dont think its far behind condition wise.

Thanks regards the actuator, thats interesting. When I get the turbos off I will be sending them to the specialists to investigate and they will assess them both and rebuild including new actuators I think. Apparently these turbos (on 997t's) are starting to corrode from general uk exposure and the metal thins until it gets to the point where exhaust gas pushes out. It is not necessarily a visual inpsection that confirms it they said.
The repair kit they are doing is to strip turbos, machine the problem face out, weld a stainless steel pre machined plate in, and refurb the turbo to new.
They can only do this though if the turbo is not too far gone... so if the metal is too thin, its new turbo time. Currently about £3500 each off Porsche or the best price I have found of £2050 plus vat each from an independant supplier but for the same oem units. (unless anyone knows of better!)

I was tempted to get some hybrids and fit some new intercoolers and get a remap (and whatever else is needed), but common sense is telling me to stay stock OEM!
 
I was thinking the hybrid route as I was writing my reply but from what I gather you need to do a lot more on top of the hybrid turbo's to gain full advantage from them.
If you've got 10 to 20 k spare go for it!
The other problem is when you start modifying the car, even upgrading the exhaust it starts to become a non stock Porsche and you'll find it harder to sell.
A lot of the mods I've done to my Gen 2 are easily reversible in a morning and no remaps have been done so the car is as it was when new.
Besides that you've got one hell of a quick car even in std form. :D

Try contacting 9e to see if they have any std turbo's lying around.
