PutPut6 replied to JJCruz's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)What year carrera? Aftermarket wheels? Many times with TPMS a fault will not be stored but that doesn't mean something is not wrong with the sensors. With a PIWIS you can watch in real time what sensors and values the system is picking up and can usually deduce from that what is going on. I actually had a cayman that had one sensor die then during the test drive after replacing it another one died and the system would not learn. So if one's dead it's best to go ahead and replace them all. If you're ever in the Tampa Bay area i have a piwis we could check it out with.
PutPut6 replied to Mera's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)If it was me personally and I could afford it, I would get a new engine. It's piece of mind. If you go the rebuild route, it will cost atleast half the price of a new engine and if internal damage is found, such as cams, lifters, bent valves, damaged clyinder head, gouges in crank and intermediate shaft teeth... The cost of parts will get you close to a new engine. Each timing chain failure engine I've seen that was still under some type of warranty ended up being replaced because it was cheaper to replace it in the long run rather than rebuild.
No, I'm not. But I think the disclaimer should be put out there. Once you drain the oil, you have nothing to tell you where you are level-wise before driving the vehicle.
PutPut6 replied to Mera's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)We have been seeing more and more cases of timing chain failure... I personaly have seen 4 in the past year, two 986s, one 987, and one 996. What we usually find is that one of the outter rollers on the timing chain somehow come loose, then get lodged into one of the cylinder head extraction pumps, locks it up, then breaks off the exhaust cam gear pump drive and then all the shrapnel is distributed throughout the engine. A Bank 1 failure can be especially bad since the intermediate shaft drive and chain are located on the same end of the engine as the Bank 1 timing chain.
The 2010 turbo uses the new DFI engine, it is an "integrated dry sump" design. It no longer has the dry sump tank that the previous turbos had. It is essentially the same engine used in the 2009-up model DFI carreras, with exception to cams, compression ratio, intake, turbos, etc...
You're going to have a really hard time knowing if the oil level is correct. Once you open the hood, the vehicle has to be driven atleast 6 miles before the oil level will read on the dash display. There is no dipstick! Unless you put exactly the same amount of oil you took out, you're going to have to drive the vehicle again and again until it's topped up properly. Porsche gives a min and max oil fill quantity when changing the oil with the filter which is 8.0L and 9.0L respectively. At the dealership, they use the new PIWIS II tester to check the oil level, it even calculates the exact amount of oil you need to add or remove to be properly filled.
There are bolts between the bottom seat frame and the rails that I have seen come loose. If your car is still under warranty, you should take it in to the dealer and they will replace the entire seat frame. For a DIY, remove the seat, take the trim covers off, find those loose bolts, remove, apply loctite, and reinstall. Porsche does not allow this for safety reasons, but it works.
Rear main seal leaks on GT3's are somewhat common, not a suprise to see. I have also seen the front seal leak (pulley side), but much fewer of those. Each can be replaced with the engine in the car so I don't know why they would be tearing the engine down. And two weeks sounds unusually long, unless they are waiting for parts from Germany.... which I doubt because parts are usually shipped VOR for an issue like that, which would only take a couple days from Germany, or next day from the US parts depots.
I've torqued those centerlock wheels on a few PDI's. All you need is that socket and an appropriate torque wrench that can handle 500nm, I believe. You'll need someone to hold the brakes while you do it also. Or if you have one.... We rigged up a way to use the CGT torque multiplier on these and it works like a charm, can be done with one person.
If you pop the side dash cover panel out (pop out the rear edge, then pull back), I like to use one of the dash support bolts, it's a good ground point. I don't like using the nut on the left side of the fuse box since it's holding down plastic. Just personal preference.
Although nothing official has been released that I know of, the latest PIWIS II update software documentation lists a new model, the 9x1 for MY 2012. I'm guessing that will be the new model designation for the 911.
PutPut6 replied to Ponch's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)Overrevs over range 1 can void your warranty!!! When we have intermediate shaft cars that come in, that's the first thing we check. Do not believe what the service manager tells you, he doesn't decide if it's warrantable, Porsche does.
This is the official News Bulletin from PCNA - Porsche 911 Turbo S to Debut in Geneva First new 911 Turbo S in five years provides 530 hp and 24 mpg ATLANTA - February 8, 2010 - The engineers at Porsche have developed a range-topping sports car designed to deliver the finest in terms of power, performance and driving dynamics: the 911 Turbo S. The heart of this exclusive high-performance athlete is the six-cylinder boxer engine boosted by two exhaust gas turbochargers with variable turbine geometry. The flat-six engine has an increase in power over the 911 Turbo by 30 to 530 hp and maximum torque is a most impressive 516 lb-ft. Despite its significant increase in power and dynamic performance, the new 911 Turbo S does not consume any more fuel than the Porsche 911 Turbo, making it by far the most efficient sports car in its class. The 911 Turbo S Coupe is EPA rated at 17 mpg city, 24 highway. The 911 Turbo S comes exclusively with the seven-speed Porsche-Doppelkupplungsgetriebe (PDK), Porsche's Double-Clutch Gearbox, delivering power to the Porsche Traction Management (PTM) all-wheel drive system. The increase in driving enjoyment is ensured by the now standard Dynamic Engine Mounts and Porsche Torque Vectoring (PTV), including the standard mechanical differential lock on the rear axle. In conjunction with Launch Control, part of the standard Sport Chrono Package Turbo, the 911 Turbo S accelerates from a standstill to 60 mph in 3.1 seconds. Top speed is 195 mph (315 km/h). Extra-light and fade resistant Porsche Ceramic Composite Brakes (PCCB) provides outstanding performance in terms of stopping power and controlled application of the brakes. Other standard equipment on the 911 Turbo S includes Dynamic Corning Lights, 19-inch RS Spyder wheels with central locking, a three-spoke sports steering wheel with gearshift paddles, adaptive sports seats, cruise control, and a CD/DVD changer. The special twin-tone leather upholstery in Black/Cream or Black/Titanium Blue, along with the new Ice Blue Metallic exterior color underlines the exclusivity of the first Turbo S in five years. The new Porsche 911 Turbo S will be at dealerships as both a Coupe and Cabriolet as of May 2010. The 2011 Turbo S Coupe and Turbo S Cabriolet prices are $159,100 and $170,200, respectively.
