    You probably fried at least the voltage regulator in the alternator when you shorted it, and it needs to be replaced.

    And when you get a chance, check out Porsche Technical Information Bulletin 36/08, stating that replacing the dual mass flywheel with a single mass is not recommended on the GT 3 (non RS), and why. 😉 Tech Bulletin 36/08

    Welcome to RennTech 1. No one said they were, but many are not balanced out of the box, which is an issue. And some machine shops simply don't want to add the cost of developing processes and tooling to specifically deal with low volume alloy flywheels they see infrequently. 2. Regardless of what you may think, the dual mass flywheel absorbs torsional harmonics from the crankshaft, which in most Porsche engines is cast, not forged, and the rotating assembly is not very closely internally balanced from the factory. Hence the need for a torsional harmonic absorption device like the DMF or suffer cracking issues. 3. The GT 3 RS engines come with a forged crank, unlike most Porsche engines, and the rotating assembly is internally balanced to a much higher standard than the regular production engines, which are two of many reasons why when new short blocks were still available, the production versions sold for less than $20K, while the GT car short block was well north of $50K. 4. Short answer: both, so while the sprung disk may make the car more drivable, it didn't prevent crank cracking. Net net: It is your money, and your engine; feel free to go in whatever direction you please. But when someone asks about using one on the M96/97 engines with a cast crank, I will continue to go with my experience and that of a shop that builds some of the best versions of these engines and recommend only doing so if the entire rotating assembly is balanced as an assembly.

    Look too large to be from the valve stem seals, and several would have had to fail to generate that much debris.
  7. JFP in PA
    Hate to tell you this, but those are a bunch of chewed up small springs, and I have absolutely no idea where they came from. 😵

    You could also get a good engine out of a wreck and install it, which is usually the lowest cost option.

    An oil analysis is not going to help, ferrous metal is most likely the sign of a major league problem developing. You need to think about trying to locate the source before something really bad happens. And even if it is an IMS bearing, you cannot just replace it, the engine will need to come apart, if for no other reason than to clean the metal out of the oil passages.

    I would run a compression test on the cylinder in question, or a leak down if you have the correct equipment to do it. If the oil is only on the tip of the plug, the problem may lie inside the combustion chamber or cylinder.
  11. JFP in PA
    Check one of the specs and see if it can be picked up by a magnet (ferrous), if it does, your IMS is probably on its way out; if the magnet doesn't pick it up, it is an alloy, probably cylinder wall.
  12. JFP in PA
    Yes, you do, unless you want to totally drop the engine out of the car.

    There is a lot of stuff in the way that has to come out first: 996 oil pump removal

    Welcome to RennTech Try posting your request in the radio code request forum section (Lost Radio Code - post your request here) and you might get a response 😉
  15. JFP in PA
    You should check that control unit, looking for signs of moisture or corrosion.
  16. JFP in PA
    Alternator diodes can be tested in the car, but you need the correct hardware to do this.

    The only thing under the driver's seat, besides the floor, is the electronic controller for the locking system, alarm, and immobilizer.

    People tend to forget one simple fact: Oil seals wear and harden over time, so the older they are, the more questionable they become. So, a seal with a lot of miles on it that is not leaking, may just decide to start doing so 5 min. after you bolt the trans back on the engine. Seals are cheap, how much your time and labor are worth is another story. We replace every seal anytime the back of the engine is exposed; cheap insurance.
  19. JFP in PA
    If it were up to me, I would update the RMS, and remove the rear facing seal of the IMS bearing so it can lubricate while you have the flange cover off to reseal that.

    Porsche learned a bit of a hard lesson from the 986/996 cars; to save costs, all those cars were wired and even equipped for options like the on-board computer and Litronic headlights, even if they were not installed when they left the factory, apparently to save costs and in expectation that both they and the dealers would be able to cash in on "post-delivery" installations of these pricey options. But what ended up happening was both the independent shops and the DIY market taking advantage of the ability to do these upgrades without the dealers because the dealers were trying to charge full boat option prices to do things like activate the OBC system, which takes about 15 seconds to do. The later cars took a different pathway and required changing out sections of the wiring harness and adding electronics that require appropriate coding into the car's communications network to function properly, which cut out a large portion of the DIY and independents simply because many lack the required parts accessibility and coding ability.
  22. JFP in PA
    Yes, I could see the photos.

    Unfortunately, the Cayenne is not like the Boxster or 996 when it comes to retrofitting Xenon headlights; you simply cannot "plug and play" Xenon's for halogen lights as the wiring harness is different, the control module needs to be installed and requires coding, as does the CAN Bus system in order for everything to function. It can be done, but it is a lot of work and requires access to a PIWIS, and those that have done it seem to question the value of what you get for the all the work and expense. This may also be why the factory never offered retrofit kits like they did for the other vehicles. It seems that most people interested in this project go to aftermarket LED kits to get around the factory retrofit issues.

    Welcome to RennTech From the factory, all Xenon equipped vehicles had auto leveling due to legal requirements in some countries, and as such had an additional control module for the leveling, leveling sensors on the chassis, and different wiring. And in the factory Xenon's, the leveling motor is in the headlight assembly, but is controlled by the external control module.

    While I have heard of people changing out injectors without dropping the engine, it always ends up becoming a "build a ship in a bottle" exercise that takes up about three times as much time and labor. Once it is out in the open, if you do not have to remove the rail to get at it, you should be golden.
