When I replaced the bank 2 vent (black corrugated pipe from head to AOS), the old one broke anyplace you tried to bend it.

Suggestion · Original poster
Also read about the air / oil separator, but seems fine too, as either OBD failures should show up (running rich) or there should be watewr in the oil (we`ll check when draining).

Suggestion
I'd do the plastic chain tensioners and the chains themselves, I believe the 2002 models had particularly poor quality timing chains (check with F6i and LN) and the more up to date tensioners have better materials in them than the older parts.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

I would replace those, but then again, i'd replace ALL the coolant hoses, the AOS (with Motorsport unit), water pump with metal impeller blades, chain tensioners, Maaaaaybe valve seats, coolant expansion tank, coil packs, belts, spark plug.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello, just recently got to look after a 996 4S manual with just 50K kilometer on the clock now. Euro car, mint inside and out, maintained at the dealership.
It was driven 10K km in 6 months, and will get the full engine out service next week (mostly because of unaddressed IMS).
The car has no issues, it had a check at Porsche for OBD failure codes, and no irregularities were found.
Whats planned to be done:
- IMS
- RMS
- spark plugs
- oil change
- oil filter change
- air filter change
- coolant flush
- brake rework (complete rebuild)
- new clutch
- new belt
- transmission fluid change
What else should be done, when engine is out of the car?
I read about the water pump being a service item worth doing, but it seems to have no issues yet. Also read about the air / oil separator, but seems fine too, as either OBD failures should show up (running rich) or there should be watewr in the oil (we`ll check when draining).
Any advice is highly appreciated!
AOS, Engine Mounts, Trans mount. Consider LN engineering Spin on oil filter adapter if you don't go with the IMS Solution (which you should do). Water Pump and Low Temp T-Stat. These things should have minimal additional labor cost if done while the engine is out. If you do them at a later date the labor will be MUCH higher. Not to mention being stuck on the side of the road.
All of the above. It might be a good idea to change the oil filler tube too. It's a plastic part that gets brittle with age. It's only about $60 but is a pain to replace with the engine in the car. The AOS is also made of plastic and it's advisable to replace it when the engine is out even if it's not showing signs of a problem.
Btw - Congratulations!
Hello I have a 2003 targa and bought IMS kit to update the engine, dropped the motor and then found out is was a new engine replaced in 2010 under warrantee, I replace water tank, thermostat, plugs, engine mounts, did Fister exhaust update (myself), belts and pulley.
So I have an brand new IMS kit , listed for $699 will sell with all receipts for $450

Unfortunately not my car, helping a friend optimise for our driving club here in Lisbon - I am still old school on my 77 930 forcefeeder
Thanks everyone for your input. Added AOS, water pump and water reservoir to the build list.
Vacuum lines are difficult to trace from euro parts dealer - any detail on which ones? Surely not the brake vacuum line?
Motor mounts are expensive, if upgrading to stiff / fixed mounts. Is it worth it? Does the added vibration kill the comfort in the car?
Cheers!
Very easy to replace with the motor in the car, so that can be done later if so desired. Lots of opinions out there on which ones, I went with RSS semi solid motor mounts on my C4s. It does add noticeable noise and vibration at idle, but it�s the �good kind� if you ask me and well worth the trade off for the improvement in handling, very much apparent with change in direction.
Btw, sounds like a good project, I did all of that and then done upon purchase and it�s been a great car so far.
Removed all plastic covers and wheel well covers today from the underbody. amazing how all that is conserved. No rust whatsoever, except on metal clips for screws.
Love the way this is built. Its super easy to dismantle, and rather well protected. I removed about 5kg of small stones from all cavities today, after the car flew off the track.
Only thing I found that bothers me: On the rear bumper there is a plastic piece riveted to it. Riveted? Really?
No car should have rivets!
Pic to follow tomorrow, once we start dropping the engine.
I would add.
- Water pump
- Low temp thermostat
- Pulley and tensors (if they need to, usually they do)
- Front diff oil
- Coils (it is recommended to change them together with the spark plugs)
- Cabin filter
You can do all these things later on if you want without dropping the engine, but, I think it is worthy to do it now while you are there.
Ps: if the car comes from Europe, I would recommend to verify the engine hours
I'd do the plastic chain tensioners and the chains themselves, I believe the 2002 models had particularly poor quality timing chains (check with F6i and LN) and the more up to date tensioners have better materials in them than the older parts.
I forget but there are a couple of coolant hoses that are almost impossible to replace without engine out service. I would replace those, but then again, i'd replace ALL the coolant hoses, the AOS (with Motorsport unit), water pump with metal impeller blades, chain tensioners, Maaaaaybe valve seats, coolant expansion tank, coil packs, belts, spark plug.
I'd also do the IMS solution to be honest.
So a couple of pictures from today.
before cleaning, man thats a parts-heavy car if you compare it to a G 911..
Can anyone say if the brownish wax in some of the images is from the Factory, or if its added as protection from someone before?
Tomorrow engine will be out, and separating the transmission we�ll get a first look at the status of the IMS. Oil leak on the bell housing is present, curious to see what the IMS looks like.
Whats the wax, original or crap? Bad looking anyway..
Lightsavers...Never knew this existed. More like $$$$$$$$ savers.
Thanks! I have one light and one bolt tab cracked...Now if they only made replacment lenses for these widebody tail lamps since most of them seem to have the vertical cracks due to stress.

My '03 had a leaking crankcase vent tube. When I replaced the bank 2 vent (black corrugated pipe from head to AOS), the old one broke anyplace you tried to bend it. Recommend preemptive replacement bank 1 &2.
If this is a track car, you will start to overwhelm the standard AOS and create a smoke screen. The Motorsport version of the AOS was created for higher G applications. Spendy though $$.
Thanks for all the tips, gents!
So for fixing the taillight we used a rather nifty tool: it melts s piece of metal wire into the plastic, a hot stapler.
First time I saw this here by my friend Pedro from Autocloche in Lisbon
