...if it were me I would be changing a few things whilst the engine is out:

AOS
Grind off /remove and replace all of the exhaust nuts/bolts and fasteners for SS
Plugs and check/change coil packs
Check coolant reservoir and change if necessary
LTT
New pipe clamps
Check water pump bearings
Air con piping
Check RMS/IMS SEAL and bearing play
Gearbox mount


Basically anything that requires an engine drop to do or will be really easy like the plugs and packs with the engine out..the last thing you want is to have to drop the engine again for something silly like the £70 AOS !

You have definitely made the right choice...I wouldn't bodge a repair with something like this engines coolant as they don't need an excuse to ***** themselves Very Happy

Plugs etc. are OK, it had a service a month ago.

I have a receipt for an engine rebuild by Hartech from May 2017. They installed a LTT then, so I guess I don't need that. They also replaced both metal coolant pipes, and all rubber hoses, so am I right to say that I can just replace the one that is damaged as the other one surely should be fine as it's only 2 1/2 years old?

As for Oil Air Separator, which part is this. There are a couple of different ones on design911, they are both called oil separators, which one is the suggested one to change?

There are 3 different ones here...

https://www.design911.co.uk/fu/cma81-cmo117-ct340-searchoil%2bseparator/Porsche/997-MKI--911--2005--08/997-Carrera-S-2005--/

Well, 2 of them are the same, but one is Porsche and the other is Vaico.


Thanks again for the help

OK, so I know the part that number for the oil air separator, but there are a couple of options...

https://www.design911.co.uk/fu/prod125933/Oil-Separator-Porsche-997-38L-C2S---C4S-99710703800/

https://www.design911.co.uk/fu/prod139635/Oil-Separator-Porsche-997-38L-C2S---C4S/

One is a Porsche brand, the other is Vaico. Would the Vaico one be OK? I'm trying not to spend a fortune on parts.

...quite surprised that this issue wasn't picked up by hartech to be honest as this would have been obvious during the rebuild? Perhaps they fitted it?

I'm not looking to point the finger, just want the car working again.

So, Should I get the Porsche brand or the Vaico?

These look like the right ones.

Would you suggest getting the pipe brackets too? As they are less than £3 each, I would think it's worth changing them too?

What rubber hoses do you think the Porsche garage were going on about.


Brackets won't be needed ..

If pipes have been recently replaced then don't do them again .. no point whatsoever .. just replace the damaged one .

Brake pipes are on inspection .. if no corrosion in the brackets then dont bother ..

AOS depends on year but if it's the central one ( square shaped ) then it can be replaced with the engine in situ so not really needed as a precaution .. only the very early 997 had the AOS the same as the 996 .

starter cable .. inspect and see if heat damaged .

I can't recommend anything other than Porsche items .. but then that's because i know it will fit without any problems Very Happy

Thanks for the reply.

My car is a 2004 Carerra S Tip, so a very early 997.

According to design911, my oil separator is this one (even though I have a very early 997)...

https://www.design911.co.uk/fu/prod125933/Oil-Separator-Porsche-997-38L-C2S---C4S-99710703800/

Is this the one that can be replaced with the engine in situ?

Is there a way to see this item in my car to be sure it's this one?

If so, looks like it's just the damaged pipe that needs replacing. And other bits and pieces to be checked out. I don't really want to spend any more money than I have too, but if the pipe is all that needs changing, then I spose that's all I change

Normally i just have the car in front of me so a simple question like this is easy ..

When at home i struggle ... as far as i know the very early cars had the same AOS as the 996 so that's best done with the engine out.

https://www.design911.co.uk/fu/pt856_859_2363_-cma81-cmo117/Porsche/997-MKI--911--2005--08/Oil-Separators-and-Vent-lines/

Upto 2005 and it seems it's the early type .

I would humbly suggest .. just let the garage doing the work order this part .. safest way if you car is a borderline one .

EDIT .. 3.6 Have the early type .. i think the 3.8 have the later type .. either way its best to let the garage sort this item i feel .. or at least advise you if it really needs changing ...

we are after all trying to keep the cost down here so unless its an early type then just leave until you have an issue .. which may well be never with the later type .
