  1. Seems strange that it would say the pressure is both low and implausible (does not understand the input signal). First step would be a fuel pressure test to find out where the pressure really is; if it meets specs, clear the codes and see if they come back. If the pressure really is low, further investigation will be required, possible pump replacement.
  2. Have your system pressure tested; takes 15 min. and will confirm if there is a leak, and may even be able to see it.
  3. More to the point, if whatever Jake developed actually works, and I have no reason to think it does not, it would be very useful to anyone with an M96/97 from late 2005 on until the introduction of the shaft less replacement. On these engines, the IMS bearing cannot be changed without totally disassembling the cases, which ain't exactly cheap, pretty much eliminating "preemptive" IMS replacements. But if you owned one, and there are a fair number of them, and this system has warned you of an impending failure, you would be thankful for the information, and then able to take appropriate steps to save the engine...................
  4. At one time, PPBB was probably the most Boxster focused; but with its founder's death, it kind of went off the beam and eventually was shut down. I'd have to agree that from an even handed technical perspective, RennTech is probably your current best bet, although there are other "pretenders" to the title.................
  5. That's what I was thinking; if any of the plugs in the engine came out, there should be "consequences", but you haven't mentioned any. I wonder if it was an "extra" left in there when the unit was assembled?
  6. For general use on multiple vehicles, look at Actron, great value for the money. For the best data and utility on a Porsche, go Durametric.
  7. Two things: Where have you mounted them? What pressure do you them for? I'm new to forums. Do you own / work at a Porsche repair or engine building business. I ask because of the reference to customer's cars. Thank you. In the rear boot. Slightly above max oil pressure ~60-80 PSIG. Yes, I own a business.
  8. P0600 is a Tip code, indicating that the CAN bus cannot communicate with the Tip's control module. Could be a harness unplugged, broken wiring, or the Tip control module itself.
  9. Check and make sure you did not dislodge or damage the leads to the crank position sensor (on the bell housing). If the CPS is disconnected, the DME does not know the engine is rotating, and it will not fire......
  10. The software system is reading the cam position sensors vs. the crank position sensor to determine the cam positions. I'd be looking at the VarioCam reluctor, the cam sensor on that side and the VarioCam solenoid on the same side. With the Durametric system, you can trigger the VarioCam solenoid with the engine idling, and should see the cam angle jump when you do; if it does not change, it could be at least part of your issue, as it may be stuck in one position. These, along with visually checking the cam slots can be done with the engine in the car. If the cam has mechanically jumped time, it would probably be easier to pull the engine to correct the issue, although it has been done in the car, albeit with difficulty. When the rear IMS bearing starts to get loose and wobble, the cam drive chains go slack, causing the "death dance" in the cam deviation values. Eventually, if the IMS does not totally fail, the chains get loose enough to start jumping time. Unfortunately, this entire process often only lasts a second or two before pistons start bending or breaking valves, totaling the engine (the M96/97 is an "interference" engine and cannot tolerate too much change in the cam angles before disaster strikes).
  11. If the cam time has actually moved, it is both "not a good thing", and somewhat complicated to correct. Can it be done in the car? Yes, depending upon why it jumped, and in any case is a nightmare to do. One of the common causes of strange cam timing issues is a wobbling IMS bearing; typically the beginning of the "death dance". The cam deviation values should be rock steady at idle, as in the posting above; if they are not, it is usually the IMS on the way out. Cams do not bend, they break; the VarioCam flange bends, throwing off the cam position sensor. This can be a relatively simple repair.
  12. I'd bet more on the drain being blocked by either debris or mold, common on these cars in very hot, humid climates. Wurth and others make some stuff that you can spray into the system that will both clean it and kill any odors at the same time. You can see the drain line from below the car and can blow some air through it to clear it before spraying in the cleaner.
  13. The sensor has a test diagnostic (voltage should read between 100 and 800 mV, ohmmeter on pins 1 & 2 should read 1.8-2.5 ohm, pin 1 to sensor housing should read infinite ohms ), test it to see if it is good or not; if it checks out, you probably have a wiring issue elsewhere.
  14. To my knowledge, Flat Six (Jake Raby) keeps records on the cars they actually do. LN may have records of who they sold the bearings to, but without verification by the shop that actually installed it , anyone can claim to have the upgrade. We get requests for this from time to time and provide a written record of when it was done. And, no, there is no way to verify if a car has one without pulling the gearbox, clutch and flywheel out..................
  15. Most good auto parts shops carry them, and they can help you with the size. Shops like Fastental (all they sell is fasteners) are an excellent source as well, and the inserts are also available on line.
  16. Considering the number of Rolex and Cup series cars that use ATE, I really have to wonder what the issue is here.................
  17. You do realize that activating the ABS/PSM system during a brake flush is not necessary? It is only required if you have gotten air into the system controls or pump during service to the system, otherwise the system is simply flushed like any other vehicle………
  18. Timesert is another source for this type of repair as well.
  19. Some of the earlier years (like yours) developed a problem with the horn contact ring in the steering column, causing intermittent problems (sometimes the horn won’t blow, other times it blows all by itself) or even total failure of the horns. Problem can usually be fixed by cleaning the contact ring and the contact itself, but occasionally the parts need to be replaced. Fortunately, they are not very expensive.
  20. Removing the filter housing will not cause you to lose all the oil, and the housing only holds about 1/2 quart or so. Be sure to install a new o-ring. And you will never get the oil out using a vacuum system from the filler.
