  1. Thanks Kevin - perhaps you're right, but I was under the car a few days back from the same vantage I took the picture, and it looked "dry." I think you're just noticing the fresh oil mixing with the existing road scum. In any case, you're right about the warranty - and I'm keeping my hopes up that they'll do all the right things to get me back in action. And just so folks know, this isn't a thread for me to ***** and moan about quality, etc. I understand the mechanical risk, particularly in buying a lower mileage car. I've also had plenty of things go wrong in the past with autos... T
  2. So strange, because the car never lost power, and it was never running without oil... but it was pretty loud at idle for about a minute. If a broken intermediate shaft means they'll likely replace the engine (under CPO), then I should be pleased, right??? Thanks - appreciate the insights. That's exactly what I thought previous post. The reason I say for some time the areas that are wet are also caked which indicates oil and road dirt mixing over time. It would not surprise me the inspection was not thoughly done! It has been mentioned from others on this board. that these inspections
  3. Looking at the last pic, it's been leaking for sometime!
  4. White987s Thanks! I just wish I could get my hands on the 5w-50, last oil change had to go to 5w- 40 Castrol Syntec. Only reason is SE Florida weather and wanted to stay with oil on the Porsche recommendation list. Hope we can have more discussions in the future. :thankyou: Happy motoring! Have a great week!
  5. No it's not, that's the problem the Mobil 1 spec sheet specs the 4.22 as non Cst! That's the error LN made! Check out the spec sheet! BTW here is a synthetic lube fact: High-quality synthetic oils do not shear back. They have natural temperature-resistant qualities, achieving multigrade viscosities without the need for unstable polymeric thickeners. Hence the concern having large spread vis with conventional oils. Can't apply the rule to synthetic. Just got a response from LN: Here it is! Here is my note: Error in your assumptions and tables on your website. You are showing Mobil
  6. Kevin, did you read throught the link (long...I know!). Here is an excerpt from Mr. Navarro: "I have included the HTHS viscosity - Mobil 1 0w40 is 3.7 cP (3.7cP * 1/.85 specific density = 4.35 actual HTHS in cSt; using the estimate of 14 * .322 yields an estimated 4.50 HTHS, which is off by only 3.4%). If there is a ~ in front of the HTHS, then it's estimated by taking the viscosity at 100C * .322 (this conversion has an R^2 value of 94%). If the actual HTHS was not available, I have shown the estimated value range for the HTHS. All the below oils have Porsche Approval and meet ACEA A3/B3 sp
  7. No need to re-check. I stand by my comment too. My source is Charles Navarro, LN Engineering, dated 7/26/08. What is your source? http://www.lnengineering.com/oil.html White 987S - Since 5w- 50 is not on the Mobil 1 site the 5w-50 quoted above is from the same source you used. BTW the spec for the 5w- 50 is the same you quoted. The 0w- 40 which is wrongly cited by you is right from Mobil 1 spec sheet! Go to the Mobil 1 site and download the sheet! Stand behind it all you want! But I would ascertain that the Mobil 1 spec sheet for 0w- 40 is correct! http://www.mobil.com/USA-En
  8. White 987s - Better go check the facts again: The vis index at 100 deg C for 5w- 50 is 17.2, 0w- 40 is 14 0w- 40 HTHS Viscosity, mPa•s @ 150ºC, ASTM D 4683 3.7 5w-50: HTHS Viscosity, mPa-s @ 150ºC ASTM D 4683 4.22 So my comments stand
  9. Don't know where you got the info on Mobil 1 5w-50 it's not on their website 5w - 50 is more viscous than 0w-40 when hot and more viscous then 0W- 40 when cold. I guarantee that the 50 oil in comparison to the 40 oil will have a higher viscosity index @ 100deg C. viscous = Having relatively high resistance to flow BTW - if a leak is evident with 0w-40, i can reasonably say it will also leak with with 5w-50
  10. Thanks--down the road, please post your results. I just noticed that Castrol Syntec 5W50 is also on the approved list. This is a little easier to purchase in MN (or on Amazon.com, for that matter!) Best Regards, Jon As far as I remember, the lastest oil approval list I saw (here in Renntech) only has either 0w-40 or 5w-40. 5w-50 was NOT on the list. I'm not saying 5w-50 will not work well but could someone please confirm whether it's on the approved list? Thanks. Mobil 1 5W-50 has been on the list at least since 2006. Porsche updates the list yearly (usually in March). W
  11. You sure it's not the IMS, rattling could mean a broken Intermediate shaft
  12. I have heard input shaft bearings that are going out do as you say! As you let out the clutch it puts a load on the input shaft.
  13. Still not sure why you think you have a mixture poblem. The codes presented point to O2 sensors. You may running up the wrong tree based on false assumptions.
  14. Unleaded fuel will always leave black deposits on the exhaust pipes. They old grey was from lead. The unleaded fuel based on it's chemical makeup, specifically MTB, will not leave grey on the tailpipes. So if you are using this as an indication that it's running rich, you are not diagnosing correctly. You need a fuel air ratio count. Pull the plugs and read the plugs, this should be a good indicator. Does the exhaust smell rich, are you seeing black exhaust?
  15. Porsche recommends the 18 for a reason. It seems Porsche does tune suspension utilizing tire size. Based on the attached article I would not go to 19's. BTW in order to keep the same diameter and rolling revs per mile, you will have to go to a lower profile tire. Results will be a harder ride, and if you get a blowout, maybe a damaged rim. Read this article and it may bring some understanding. http://www.europeancarweb.com/features/epc...test/index.html
  16. One would think a valid road test, and working the clutch to try and make it slip would have been done, since we are only talking a couple of weeks. Also They should have noticed a higher than usual pedal. These things grab pretty low. Unless of course you have a RMS leak whereas oil has gotten on your clutch disk. One would think that the dealer inspection would have found an RMS seepage. A good way to see the condition of the clutch is to get it in high gear at slow speed and see if the clutch slips or the engine lugs.
  17. What weight oil are you using? I noticed mine seems to do it a lot less after using the oil on the Porsche recommended list. I use Syntec 5w- 40 as per one on the Porsche recommendation list. Before I changed it I think there was 15W- 50 in it. I would get the lifter chatter for a few seconds and it would dissappear, just leaving it sit for a few hours. Going to the 5W-40, I hardly notice it anymore.
  18. Anybody know if the 40 th anivesary mufflers are actually Porsche performance mufflers and if so will fit a 2000 996?
  19. Do a search on tires here and you will find more opinions about every tire that will fit these cars than you ever wanted to read! I'm personally a fan of Michelin Pilot Sports. I think in terms of wet/dry traction, noise, wear and other key factors, these tires are as good as any. Will Go to the tire rack and look at the survey and test results. I just purchased a set of Bridgestone 960A pole positions. For the money they were among the top picks. BTW they have a 40K mile wear out guarantee, and have excellent performance marks. They are really quiet, and ride suburb and handle excep
  20. Look at this: http://www.fabspeed.com/996_GT3.html Then go down click the following! Shows a cross section of the Porsche can. PRODUCT VIDEO: 996 & GT3 & 997 Muffler Exhaust
  21. It could be the cats where as the elements loosened up, or the PSE mufflers themselves where as the baffles broke free inside, or the flapper valve. Actually I think sometime ago I read an article in Motor Trend on long term 2003 or 4 Porsche Carrera test the only thing that became faulty over a period of time was the PSE exhaust. It rattled which required the muflers to be changed out.
