    It is more complicated than you might imagine. First of all, there is a lubricant that is distributed throughout the system, and you must add the correct amount of the oil when you replace components (the factory service manual has a table listing how much for each component). Secondly, if you opened the system, you should replace the system's receiver dryer before evacuating and recharging it. A new one costs about $60, but will save you a ton of headaches.

    Glad to hear you are making progress. It is almost impossible to say why the old oil was so black. I would send them a sample of the DT40 when you drain it as it will give you an idea of where the engine is now, so you know where you stand going forward.
  3. JFP in PA
    It is not a single value, it is a curve because the system is variable, from 0 to 25 degrees depending upon the engine operating conditions.
  4. JFP in PA
    That is for the VarioCam which is a fixed change, yours is a VarioCam + system which has variable timing changes with engine RPM.

    You need to look at the cam position sensor in question on bank 2, which either is not sending a signal, or possibly an intermittent signal. I would be looking at the wiring to that sensor as well, as a chaff or break can also cause this type of fault.
  6. JFP in PA
    That is up to you, we use the original part number, and buy them from board sponsors Sunset Porsche.
  7. JFP in PA
    You are looking at the transmission mount, easily replaced.
  8. JFP in PA
    This is exactly why you have a PPI done.
  9. JFP in PA
    You are at a "toss up" cross road. The oil leak could be from either the RMS or the IMS cover flange (they are both known to leak); both are low cost parts items, but the big money is getting at them (the trans, clutch, and flywheel have to come out, which is about a $2K shop bill). And if you had this done, you could have the rear seal of the IMS bearing removed so that it can be oil lubricated going forward (we have done many of these, it seems to help the bearing long term). If the rest of the PPI is good, try knocking the price down to reflect the expense to fix these issues; if the seller bites, you are golden; if he balks, move on, there are other cars out there. And an oil leak from the IMS flange does not mean that the bearing has not been getting lubrication, it is a sealed and grease packed unit that happens to be partially submerged in oil, which is why the flange can leak.

    Welcome to RennTech We have seen this before. Some of the cars had leaking seals on the IMS flange cover, which Porsche replaced under warranty. But they only replaced the cover, not the bearing. In addition, as the car is an 06, it carries the oversized third design bearing, which cannot be removed without disassembling the engine. And before you ask, yes, the third design still are subject to failures.

    You can easily test the pump by activating it a Porsche diagnostic tool like the Durametric system.

    First of all, welcome to RennTech The multi-functional switch is not designed to be serviced, so taking apart is questionable. Secondly, we store Tip equipped cars for select customers, sometimes for more than a year, and have not encountered the type of issue you describe, so I don't feel leaving one sit in one position for prolonged time frames is necessary involved. I would also note that we see more problems with this switch from moisture or oil leakage. It is not uncommon to find one of these units with accumulated transmission fluid inside them, and cars that live in high humidity environments (I note that you live in Hawaii, you lucky dog!) tend to be more problematic than those from dryer areas. Lastly, we have had absolutely no luck with aftermarket replacement switches, they simply do not hold up. Stay with a factory replacement.
  13. JFP in PA
    It could be done both cheaply and easily with an aftermarket system, but if you were trying to go factory, it is going to require considerable effort and expense to get everything located in the car and activated with a PIWIS system.
  14. JFP in PA
    Probably the mechanical switch in the column itself. If that has failed, you might consider getting the four stalk system from a wreck and then activating both the OBC and cruise if your car didn't have them from the factory.

    Quite often, the actual corrosion in the battery cables occurs on the inside, underneath the crimped ends, so is difficult to impossible to see. This is why most shops run voltage drop tests across the cables; a drop of more than 0.5V says the cable is bad, regardless of how it looks.
  16. JFP in PA
    Try bypassing the switch and see what happens; if it starts fine, its the switch, if the problem remains. it is elsewhere.
  17. JFP in PA
    I would start by checking the wiper fuse in the fuse panel under the driver's side dash.

    By far the most common reason TPMS systems act up is dead or dying batteries in the sensors inside the wheels. While we have replaced literally hundreds of the wheel TPMS sensors because of this, we have never had to replace the control units in a Porsche. If you take the car to a well equipped shop, they can place a hand held diagnostic tool by each wheel and quickly determine if the wheel sensors are out. Takes about 5 min.
  19. JFP in PA
    I would budget for between $1000 and $1300, depending upon what parts need to be replaced, all in including alignment for the front struts.
  20. JFP in PA
    Good point!
  21. JFP in PA
    It is not that simple. The strut bearing swap requires removal of the strut assembly, compression of the spring, and then disassembly of the strut itself to get at the bearing. And after putting the car back together, you will need an alignment. If the strut cartridges themselves have a lot of miles on them, or show signs of leakage, etc.; now would be a good time to replace them as well.

    I think you will find that the valve opens much sooner than 65 inches of water. And yes, that is the valve on the cam cover on the other end of the long hose from the AOS. You still have something amiss in the sump evacuation system, as these are very low tension ring engines and not designed to work well unless there is slight vacuum in the cases. When your engine goes to positive pressure, the rings are no longer able to control the oil and you get the smoke. It should not be able to go from vacuum to pressure.
  23. JFP in PA
    It does sound like the strut bearing, which is a common problem.
  24. JFP in PA
    If I were you, I would be saving a sample of that oil to send out for analysis. And if there is substantial fuel intrusion into the oil, the next question becomes why?
  25. JFP in PA
    Pre oilers would not do anything to address abnormal cylinder liner scoring and wear as the oil would simply just wet the bearings and not the cylinder liners.
