    +1 A lot of pople been screwed by these folks..................

    As much as some would like to debate the utility of the LN lower temp thermostat, it has proven to be a valuable addition to street driven cars. It significantly lowers the operational (steady state) temperatures, and even more importantly also lowers the oil temps. UoA’s have shown that oils stay in grade longer. And while some argue that water and fuel remain in the oil because of the lower coolant temps, again the UoA’s have totally refuted those claims as well. We have literally dozens of customers running them, both on the street and the track, and all the results have been totally positive…………………

    Freon is a gas at ambient temperatures, it would not create a puddle on the floor. That is most likely coolant.

    Both versions are capable of activating the pump for the bleeding/flushing on a 986.

    The ABS/PSM control system is a very expensive unit. If you get a used one, be careful, they are sensitive to dirt, moisture and corrosion, so know whom you are buying it from. You will also need access to a PST II/PIWIS or Durametric system to swap it out as it requires a special bleeding sequence and activation. Are you sure it isn't a cracked line? They are a lot cheaper.............
  6. JFP in PA
    Yes, it just pops off. If you need to "help it" come loose, try sliding something like a tongue depressor under the edge to get it started. Once you have the trim off, it works like this: Don't be concerned if you need to snap off the old bits as you will not be using them again...........

    The LN 160 stat is fine for the street, we have a lot of customers using them with no issues.
  8. JFP in PA
    It could be a defective hose, but that would be pretty rare.................
  9. JFP in PA
    Glad to hear you worked it out.
  10. JFP in PA
    I would agree with Maurice, move the clamps. If it still leaks, you may have a small bit of debris inside the hose that is keeping it from sealing. We have put several sets of these Precision modified tubes in for customers and not had any issues, so it has to be something small.

    Don't beat yourself up over it, "fecal matter occurs". When the fluid level gets low enough, and the car is on an angle, it is fairly easy to uncover one of the ports in the master cylinder and suck in some air without the low-level indicator lighting up. Flush the entire system and let us know how you make out..............
  12. JFP in PA
    Couple of possible alternatives: You may have just stripped the plug, which would just require its replacement; but you may have also stripped what it screws into. As you have no idea of the system's integrity (e.g.: if the plug will stay put or not), you need to have this looked at. If that plug drops out while on the road, the results could be a disaster.
  13. JFP in PA
    You sound like you had very low fluid (adding 250 ml is a lot), and now may have gottem air into the system. I would suggest getting the system flushed with new fluid, and see if the brakes recover. If not, you may need a new master cylinder.

    Cars with the Tiptronic are no more or less prone to IMS failures; fewer are reported simply because of the ratio of Tip cars to manual gearbox cars. RPM limits also do not factor into the failure either. The IMS bearing is believed to die because the seals on it fail and allow motor oil to wash the high pressure grease out of the normally sealed assembly, and then the trapped motor oil breaks down and the bearing has little, if any, lubrication. Obviously, this process is independent of the transmission type. If you would like to learn more about how this process takes place, I’d suggest the LN Engineering and Flat Six websites will provide you with more data than you probably really want to have.

    This is usually a mileage tripped alert (time for an oil change) rather than a trouble code, and can be cleared with the Durametric or Porsche systems only. If there is a real issue, the Drurametric system should also see that as well.

    You are assuming that the newest poster would bother to run a search and find it.........................

    Like most OEM’s, Porsche no longer prints any service manuals, but only makes them available online via subscription. You need to also be aware that Porsche has a reputation for severely protecting what they see as their intellectual property, so be careful buying pirated versions.

    Jake as developed (and continues to improve) an interesting system, particularly for those with the 05-08 engines that cannot easily be IMSR retrofitted. The system seem to work well and I have not heard any issues other than DIY installation hang ups, which he has moved to address with better instructions and changes to the system to make it easier to do. Any M9697 engine with an intermediate shaft is at some risk of suffering a failure. The early cars are better known because they have been off warranty longer, have had more owners comment on forums such as this, and have more road miles on them. But the later engines still suffer IMS failures.
  19. JFP in PA
    I really would not be driving a car with a coolant leak around; if it totally fails, you are stranded, and you could do some irreparable harm to the engine if it overheats (alloy engines do not like being overheated). Park it until it is fixed.

    The AOS (when new and correctly functioning) should show a vacuum of about 5 inches of water at the oil cap with the engine running (temp is pretty much irrelevant). When the AOS craps out, the vacuum level at the cap sky rockets to several times the correct level, making it nearly impossible to remove without a substantial degree of effort. It is also not uncommon for the engine to stumble or have the idle speed change with the cap is removed (remember, you just vented an engine vacuum source).

    The 9A1 is a much better design than what it replaced, having addressed many of the issues of the M96/97. That said, only time will reveal any new potential flaws. You are correct on the DFI/carbon deposit issue, but the DFI also shortens oil life (much higher fuel intrusion) and introduces 1700+ psig fuel pressures that have shown some pump failure related issues. Unfortuantely, because any of these problems would be covered under warranty, little information has leaked out to the aftermarket to date.

    Calibration of the fuel system is a time consuming process and requires access to a PST II/PIWIS unit to accomplish. The tank has to be totally drained, then refilled with a specific amount of fuel for the process. Disconnecting the battery is not going to do it.................
  23. JFP in PA
    It will fit the V8 Cayenne, but not the V6 version which uses a different size filter more common to VW and Audi..............
  24. JFP in PA
    We prefer the Actron because it has a side pressure vent line to dump the system pressure before disconnecting (saves on clean up and smell), which can also be used to test fuel delivery rates. As it also comes with an collection of adaptors, and Acton/SPX introduce more adaptors at low cost when new systems come out, it never goes out of date and can be used on just about any make. I would also be concerned about someone using the A/C unit on an A/C system after it has had gas in it; I do not know how the A/C would respond to fuel or fuel residues in the system as most are pretty bad about comtamination................
