  1. This is in reference to my '07 997TT with FVD sport headers and FVD sound version exhaust with 200 cell cats. Everything else on the car is bone stock including the ECU program. She runs just fine. The car is low miles and the full exhaust has been on the car for over 3 years. I get random CELs, only 2-3 times, with OBD code P2099 "Post Catalyst Fuel Trim System Too Rich Bank 2". These are my thoughts: 1. Cat going bad 2. O2 sensor going bad 3. 'Occasional' random CEL due to the high flow setup 4. Bad gas My guess is that it's not a big deal, and I have reset the code. I will probably have the dealer check it out just to be sure all is good. Am I missing something here? Any other thoughts to add? I hardly drive the car... it has 10K miles on the clock.
  2. That's interesting info. I just got done reviewing PET diagrams and it looks like the following: 1. In the 996 non-turbo cars, including the 996 GT3, the brake lines and clutch operating cylinder are run off the same fluid, brake fluid, with a common reservoir. 2. The 996TT and 996 GT2 have separate circuits with different reservoirs. The brake lines are fed with brake fluid while the clutch hydraulic lines are fed with PENTOSIN. 3. The 997 non-turbo cars, including the 997 GT3, appear to have the same setup as the 996 non-turbo series. Brake lines and clutch lines have a single brake fluid reservoir. 4. The 997TT, same as the 996TT, has separate circuits. Brake lines are fed from the brake fluid reservoir while the clutch hydraulic lines are fed from a separate reservoir containing PENTOSIN. Thanks, RFM. I really didn't want to stick my arm way up under there anyway! :lol:
  3. Loren et al, I plan on changing the brake fluid in the 997TT with a Motive Power Bleeder. Is the clutch bleed valve in the 997TT still accessible and in the same location as in the 996 series (top of the tranny)? Are there any significant technical/procedural differences that I need to be aware for the 997 series? I haven't actually gotten up under the car yet, but the procedure surely can't be that much different from the 996. Cheers
  4. Excellent. Thanks, Loren!
  5. Does anyone know the charging specs for the Porsche battery maintainer? Specifically, what are the spec differences between motorcycle and auto modes? I'm talking about the long, slender maintainer that looks just like a CTEK unit (see pic). I have 2 of these and I can't find the owner's manuals. I also can't seem to find the exact same CTEK model to reference specs. Is the manual online somewhere? I just picked up a Braille AGM sealed battery for the GT3 and need to know if the Porsche maintainer will be appropriate for use with the Braille battery.
  6. Thanks for the response, Loren. So, is PST2/PIWIS the only way to reset my service indicator? Durametric's website doesn't have a tool listed for the 997TT... only the base 997 and the 996TT are mentioned. Can the dealer reprogram my service indicator to go off in 2 year intervals? Interesting... I just got back from Wally Mart with a case of 15-40... j/k!!! :D
  7. This is in reference to my 2007 997TT. My maintenance schedule booklet dated 5/07 lists 'first minor maintenance (years 1, 4, 7...)', 'second minor maintenance (years 2, 5, 8...)', and 'major maintenance (years 3, 6, 9...)'. Each service includes an oil change... which means the oil needs to be changed once per year if mileage limits are not met. My service indicator in the OBD is telling me to head in for service (one year has passed). The maintenance schedule booklet here on Renntech is dated 9/07 and alternates between a minor service (years 2, 6, 10...) and a major service (years 4, 8, 12...) which means oil changes every 2 years if mileage limits are not met. Why the difference and why the change? Per the latest 9/07 schedule, I should just head in for the dealer to reset the service indicator. It looks like my '02 C2 cab required annual oil changes if driven < 9K miles/yr, and then in 2004, Porsche recommended oil changes every 2 years for the base Carrera and even the 996 GT3, and then my 5/07 booklet says annual oil changes again, and then the 9/07 document says every other year for oil changes. WTFrick is going on here??? Loren, do you have a good explanation for this one? :P Thanks! :renntech: RJ
  8. I completed the brake fluid flush with ATE Typ 200 and a Motive power bleeder. It was a little difficult to keep an eye on the fluid level in the reservoir due to the gold color and the hidden nature of the reservoir, but the procedure was very straight forward. I could have done the entire job with one liter, but I wanted to be extra thorough with all the bubbles and debris flying out of the nipples, so I ended up using 1.25L. Interestingly, "ATE" is molded into the brake fluid reservoir. The only point of interest, sort of, is that the factory routes the brake pad sensor wires through the rubber covers for the bleed nipples as shown below.
  9. Thanks, Loren. I did the right rear and then it started to RAIN!!! LOL So, I just moved the truck inside the garage... and onto the left rear. Since I'm working solo, I'm not pumping the brakes while bleeding. When I moved the truck inside, the pedal felt fine. I use the Pepper to tow and noted quite a bit of debris in the fluid at the right rear (15K miles on the odo) but no bubbles. I can't imagine the pumping the pedal procedure being necessary unless there was a significant amount of air in the system. Thanks again for the help. :renntech:
  10. I have much experience on 996 brakes and recently changed the front pads on the Cayenne S. Now, I'm about to flush the Cayenne S brake system with new ATE Typ 200 DOT 4 fluid. Renntech search yielded one pertinent hit RE MY2004 Cayenne brake flush and Loren's response was that the procedure is basically the same as a 996. Cayenne manual states that the flush takes about 0.95 liters. A couple of Q's: 1. Do the same pressure rules apply for the Cayenne? Keep the Motive bleeder less than 20 psi at the master reservoir? 2. It's a Tiptronic. Are there any other lines connected to the brake fluid reservoir that need to be bled besides the 4 calipers? Cheers
  11. I have been dealing with GT3 Cup cars and street cars since the first Cup cars came over from Kadach (German firm that sells used Cup cars) Not one time have I seen a failure or heard of one (and I deal with shops and race teams 24/7) You are correct in saying: the case was never designed for that, but it was also not designed for 1000hp twin turbo setups (but they work fine) I'll see if I have a recent pick of your "Made in Spain" engine case and show you the internal webbing. You'll see quickly that is "Ok" to lift them there. Your case really isn't much different than all the cases before it (66-98) and we have been lifting 911's like this since 1966 (not me.. I was born in 70.. lol) but you get my point. Now, that being said, The tech who lifted the car should be *shown* how to use a small piece of wood in the center of the jack pad to keep this from happening.. or they need to BUY the proper pieces for their lift if they are going to TOUCH 986/996/997 chassis' I'd be miffed also B Thanks, Brad. It was a loooooooooong day at work and I'm just now catching up on all this! As noted in my response to Craig, I felt some ridges near the indentation last night and was too tired to figure out what was really going on... I thought those ridges may have been something bent or compromised. Later I realized that the ridges are cast into the case. The 'dent' looks cosmetic. BUT IT STILL P*SSES ME OFF!!! LOL Thanks for the reassurance and if you find those pics of the inners of the Spain cases please post them. :thumbup:
  12. Craig, thanks for the reply. I know guys have been lifting from the case for years... I'm just not a big fan of the procedure for the reasons you list above. It is reassuring, however, to have the input from Brad's post. The indentation from the jack looks cosmetic. Late last night when I was trying to look at the case I felt some ridges near the indentation but I didn't really get a good look at things since it was late and I was dog tired. I thought something may have been bent or compromised, however, I later realized that those ridges are simply cast into the case. I'm peeved that the guy didn't use something to protect the case like a piece of wood or a hockey puck!!!
  13. Thanks for the feedback. I'm angry at myself for not keeping an eye on them... but should I HAVE TO??? :angry: Loren, do you know of any failures (either in the case or at the tranny interface) related to jacking the vehicle from the case? Surely, the case wasn't 'designed' for that. The mechanic is from a Porsche race team in the 80's out on the west coast. Unbelievable.
  14. Take a good look at my crank case and tell me what you think. There are three pics. 996 GT3 crank case The car was at a local shop for a tech inspection and while they were loading it onto a nice Rotary lift, I was checking out some of the old P-cars in the shop. I turn around and guess what I see... the arse of my car is in the air being jacked up by the bottom of the crank case! :soapbox: No, I'm NOT a fan of jacking up the car by the case. The car was too low to get on the lift, so they jacked the rear from the case to get the lift under the four jack points. I didn't notice them jacking up the rear since I was checking out other rides. :eek: When the inspection was done, they had to jack the rear again to get the car off the lift. I checked the case bolts and all seems tight. No obvious cracks or leaks in the case anywhere, however, there is a large indentation in the vertical fin of the left side of the case (outlined in the link above). I think the indentation is where the rough edge of the jack met the case. Should I be worried about the crank case or is this just a cosmetic issue that should never have occurred in the first place?
  15. Craig, thanks for the reply. I did a thorough draining and then refilled her with 7.75 US quarts... just to be safe. I couldn't see squat with the dipstick for the very reason you mention above. :blink: But the dipstick proves it... I have a Cup car! :lol: Anyhow, .25 quarts more and the e-gauge read about one bar above the middle of the range. I barely got in 8 quarts. It's far too easy to overfill the engine. I ended up filling the oil with the dipstick removed. Cheers
