    997 Carrera 4S Tiptronic 2006
  1. I think we misunderstand each other here I was refering to factory parts and not aftermarket _Factory standard exhaust have a single exhaust pipe coming to the tips ( per side of course) with the option to have the oval exhaust tips in chrome for the Carrera or a dual exhaust tip for the Carrera S, option being also to have it chromed for the carrera S _The Porsche Sport Exhaust ( orignial porsche not aftermarket ) has dual exhaust pipe ( per side so 4 in total ) + the dual exhaust tips ( per side) this is what I have on my car Anyway the factory PSE can be recognized easily by the 2 diameters on the exhaust tips, one small one big on the outter side Of course with aftermarket stuff everything is possible
  2. PSE = 2 exhaust pipe coming to the exhaust tips Standard = 1 exhaust pipe coming to dual or single exhaust tips
  3. I have been through low voltage symptoms like windows not closing fully when the door is closed, slow cranking I am sure you have done that already, but what about charging the battery for one night, if you notice a difference you know that you either have an alternator or a cable to change
  4. Hi Rik, Your post sounds exactly like what happened to me, my 997 C4S tiptronic was always serviced wtih 5W50 at Porsche ( 137 000 KM) At the last service, I had to change Porsche garage due to schedule issues and I noticed they put Castrol 0W40 ( approved oil...) Shortly after, 1 month, I got the ticking noise and it got louder and louder on the right bank 4-5-6 , an oil consumption of 1L every 1000 KM, normally I was doing 1L every 6 to 7000 KM+ a lot of carbon black on the left exhaust I went back to the garage that did the service ( knowing damned well what happened after reading the great article from Hartech) and they told me it was a hydraulic valve lift. Since I had a guarantee from Porsche, I decided to see another Porsche center for a second diagnostic, before I finished explaining to the guys that I had a ticking noise, the man interrupted me to say: " and you a black exhaust pipe and using oil", he mentioned that this is rare but happens and they will replace the engine for free Took a month to get the car back, they had to do a borescope picture, get porsche appoval, messed up schedules... The engine was delivered with everything new on it, generator, oil separator, intake manifold, water pump, .... even the exhaust manifold, ( i heard that the engine is tested at the factory before being delivered ) anyway, to my point, when I got the car back thanking the chief mechanic with a box of chocolates, the guy told me, please now only use Mobil 1 5W50. I guess this comment was not innocent I read the hartech article and I have to say, it did sound scientifically bullet proof, but my car is a tiptronic with the third radiator so the cooling capacity is in theory higher and I was not expecting it to had score cylinders When I read your post I am more thinking that the scoring cause is the break in the oil film, one may say that this is a consequence of a too high cylinder deformation caused by heat but I guess the 0W40 is too thin, and it might happen sooner than with the 5W50 I think the 3.8 has a real desease, though the we don't hear IMS issues, it seems that every car with high mileage on the net had the engine change done Looking at prices of 1 gen 997 carrera S today, well less than 40 000 euros, and knowing an engine rebuild will ensure you another 100 000 to 150 000 KM trouble free for 7 to 10 000 euros, it is still worth the money to me I would like to mention also that when I had the cylinder scoring, I reved up the engine just like before, besides the ticking noise, and oil consumption the car was running perfect
  5. I looked up the mufflers reference number on Porsche.com, they are indeed different on the 96.05 and the 97.01 engines and that probably because of the exit pipe, I am not sure that the exit diameter would be smaller it is probably centered differently due to the different tail pipe design Cats have the same ref numbers for the 2 engines, therefore the inlet pipe will be the same diameter, also the connecting sleeve has the same ref number... and both engine can have the XLF ( Porsche Sport Exhaust ) as optional, and for this there is only one type of muffler ( actually 3 references for the different region noise tolerance but they would look identical from outside ( I know from experience) Good luck!!!
  6. Hi, Please find pictures of the tools First is the Socket insert tool number 300 then is the socket tool number 14 Third is the extension bar tool number 15 I am quite sure that these are Hazet tools and you probably can find them on their website sparkplugtools.doc
  7. I don't believe that the special tools are necessary, but If you want I will send you the pictures ( I am in the office right now... :renntech: ) The socket is standard, The socked insert, is strange, I guess it is acting like a small extension to put on the plug side as the plug tubes are long and you don't have the space to insert a long socket in one go as you have the muffler holders on the other side The extension bar is special, it has a barrel connection, instead of a square one, I guess it is to avoid the usage of a cardan and therefore gain space and be able to have the right torque numbers on the plug My solution to this was to buy a socket with a cardan in 3/8, I bought one at autozone last time I was in the US, but I never tried it, from experience I know it would work though ( you need a dyno wrench on 3/8 also...) the role of the cardan is that it folds and therefore allows you to put a rather long socket in the plug tube Before that I also did it with a normal 1/2 tool box, I had to put the socket in the tube first, connnect the cardan, and then connect the extension bar, the reverse way is more tricky you need to hold the socket with a thin piece of metal once you are done and then extract it somehow, magnet..., not an easy thing If you are properly equiped you should be able to use your dyno socket wrench with the cardan being straight, don't use a torque wrench or tighten plugs with a floded cardan On some plugs I could not use the torque wrench, I therefore applied basic mechanic knowledge and everything worked perfectly http://www.ngk-sparkplugs.jp/english/techinfo/qa/q18/index.html Regarding your cracked coil, I drove with one like that too for 2 years before changing it, I ulitmately changed it when I did the plugs, but there was no change at all on how the engine behaved, I also did not have any misfiring by the way your pictures motivated me to take the front bumper and clean the radiators, I did it with a high pressure hose, it is amazing what comes out of it, It is a very easy procedure in the end, it took me a good 2 hours, but I am sure if I had to do it again 1 hour would be enough Good luck with the plugs
  8. Quick update to all, RFM was right, 99733104301 had play in it , you can feel it when the part is removed from car I changed them on both sides, the problem is now solved Thanks again
  9. No need to remove the muffler for the spark plugs, you just need the right tools, It is off course easier without, and it will be a bit of torture Below is the extract from the Porsche Manual, I bought a spark plug wrench with an integrated cardan shaft at Autozone, it needs to be in 3/8 and you need a 3/8 extension too, there is little space in there, you will understand when you will start Also, I did change the spark plugs at half the advised KM ( 45 000 KM) just to be sure, there were really looking good, like new...and there was absolutely no difference in fuel efficiency or engine running at idle, ask yourself if you really need to do that? the Porsche Bosch 4 electrodes are there to last 4 times longer than before and it does work well I would avoid taking off the muffler, this is absolutely unnecessary unless you want to change them, I did it myself to reweld them as there was a vibration at high RPM due to a broken metal strap that maintains the pipe together on the PSE..., The exhaust holder pins have a high chance to break when you will try to unscrew them, and believe me I used a lot of WD 40, each holder is 350 USD, + new screws, + 2 new sleeves as they need replacement all the time it can be a 1000 bucks, the socket wrench with cardan shaft is 5 bucks... Good luck Removing spark plugs Shield for ignition coils 1. Remove the 2 M6 x 20 fastening screws -arrows- for the shields on both cylinder heads and remove the plates. 2. Unplug cable plug for the ignition coils. To do this, slide the rubber grommets upward first. Press locking tabs on the respective ignition coil and pull off the individual plugs. In the interest of better accessibility, unplug the cable plugs for the solenoid hydraulic valves. Screws for ignition coils Loosen two M6 x 25 fastening screws -arrows- each per ignition coil and remove the 6 ignition coils individually.

  10. You are reading in mind, though I still have a smile on my face despite the bad stories, I cannot get to the idea of driving something else, you know "cars with the engine in the wrong place", the front... I will see how it goes, maybe I make friends again with my C4S with a new engine
  11. I am going through the same story My differential is new as changed with the tiptronic under guarantee My sway bar links and bushes are new The transaxle ( I guess you mean the main cardan shaft between rear and front), has been replaced by Porsche without asking, as they have seen that the rubber spacer was worn, After all that the noise is still there I tend to think that most people don't care that is why it is seldomly reported I also heard the dual mass flywheel story, and that 1 car out of 5 does this without known reason I will be changing the control arms ( not the coffin one the other big ones ) on the back as I get some clunk when gently braking, if there is some change I will let you know now I don't have my car, as I got the nasty cylinder scoring and Porsche is changing the engine under guarantee ( an engine in 85 000 miles... no comments), I asked them to check the rear CV joints also
  12. Thanks RFM, I know about the longitudinal move on the rear ones ( about 3 to 4 cm move), but on the AWD 911 the front CV hardly have play The left one would have 1 mm where as the right side would have around 5mm The difference with the rear is that you hear this "Clonck Clonck" everytime you move the CV shaft, on the rear ones you feel that the movement is dampened by grease in the CV joint, it must be a different system Hence my question: is this normal ? My rear potential CV issue is all different, I hear a slight clonk when I give gas, the same noise can be reproduced when I lift up the car, now I don't know if this would be the differential or not I will try to post again the video
  13. Hi Everyone, Since I started to learn about CV joints ( see previous post), I tested the rear ones too as I get a light "click" whenever I give gas When I move the wheel and put my hand on the inner CV joint, I do fell that the noise comes from the joint but the differential is just behind and it is not very clear, the differential is new as I got my tiptronic changed recently, also there seems to be no play between the joint and the shaft, see attached video Do you think it is time to renew them, my car is 85 000 Miles, or is this normal The other side seem to be also making noise but then again, the differential makes noise on the other side and it is not obvious to locate the culprit I would have believed that if I make the shaft slide the noise would have changed, but it keeps on being the same, so maybe this is just the differential or maybe this is just the normal noise of CV joints? Let me know what you think about the mileage and 911 CV joints. Thanks C4SCVrear.mov
