    I have absolutely no idea what that is supposed to do and have never had to do it on any Porsche model.

    A quality digital manometer can be found on Amazon for less than $40, and is an excellent addition to any toolbox. A short length of hose, a barb fitting (Amazon), and a spare or used oil cap and you are in business. With all the AOS problems these cars have, long term it will save you $.

    As long as you plug or cap each line as soon as disconnected so that air does not leak back into the ABS system, no PIWIS or Durametric system activation is needed. And when reassembling everything, put a dab of anti-seize on the caliper mounting bolts before you torque them.

    Both codes point to a vacuum leak at idle: P2187 Oxygen Sensing Adaptation, Idle Range, Bank 1 (RKAT1) - Above Limit P2189 Oxygen Sensing Adaptation, Idle Range, Bank 2(RKAT1) - Above Limit Possible fault cause - Incorrect main charge signal - Intake air system leaking - Fuel pressure too low - Volume supply of fuel pump too low - Mechanical fault in injection valves - PCV valve leaks - Cap of oil filler neck leaking - Leaks in exhaust system - EVAP canister purge valve mechanically faulty (hangs open) - EVAP canister purge valve output stage faults As you replaced the AOS, I would start by checking the oil cap vacuum at idle: M96 & M97 Nominal crankcase vacuum is -5.0" (-4.0" to -6.0") of H2O (not HG). MA1 Nominal crankcase vacuum is -15.0" (-14.0" to -16.0") of H2O (not HG).

    Yes, but you do not have to have the cam covers on if you use the correct tooling to hold the cams in place with the covers off:
  6. JFP in PA
    I will assume, for the sake of argument, that the engine is out of the car, which makes all of this one Hell of lot easier. Yes, you can do both banks at the same time; this is the normal process in a from scratch engine assembly process, only you are doing it in reverse. Where people tend to go wrong is when they hand rotated the engine with one or more banks completely out of cam allocation, not knowing you can actually damage valves doing that. As for the IMS, once you have the cam allocations completed on both banks, you need to lock the engine at TDC, and lock the cams, before proceeding.

    These lifters have problems because of their design, which allows crud to accumulate inside their internal oil passages. How long they need to soak is totally dependent on how badly they are fouled. Normally, if we get a couple of bad units, we just replace them all with new.
  8. JFP in PA
    I have never understood why people use the Motive unit dry; the one in my shop has seen more individual Porsche's than you can imagine, as well as a lot of other makes, and using it "wet" has never been a problem.

    As a rule, these maintenance plans are designed to turn a healthy profit for the firm offering them, much like extended warranty programs. While newer cars do have a lot of electronics in them, some unnecessary, there are still a lot of things a "shade tree" mechanic can do by themselves.

    Unfortunately, the words "Porsche" and "discount" tend to be mutually exclusive....................😵
  11. JFP in PA
    I don’t believe Porsche ever offered the tail light’s internal components separately, only providing assembled lights. Normally, dim running lights are a sign of a weak or corroded ground connection.
  12. JFP in PA
    Yes, you can remove and re-center the steering wheel, without doing anything else, but after getting an alignment you are going to need to reset the steering angle because of the suspension work.

    Re bleed the slave.

    A PIWIS II is very old and is no longer supported by Porsche; it also will not work and several late model Porsche vehicles that came out long after the II was killed off, partially because it was being cloned. The current system is the PIWIS IV, and the version level is somewhere in the 40's. Unfortunately, unless you are willing to jump for several thousand dollars for a decent stand-alone device, plus a subscription for updates, be better off with the Durametric.
  15. JFP in PA
    Search always your friend, as this has been covered many times. Short of jumping $20,000 (first year lease) for a real PIWIS system (not the clone junk sold on the internet for cheap money), Durametric is about as good as it gets. There are other options, all of which have their limitations as well. Several companies feature "Porsche" models, none of which have shown me very much; several require annual subscriptions, and then tell you that many of the so-called Porsche features will be released at a future date. Out of the box, Durametric gets the job done, it isn't perfect, has perhaps 85% of the factory system functions, which time has proven are way more than enough for some people to get themselves in serious trouble.

    As these cars age, and parts become superseded or no longer available, it becomes increasingly difficult to keep them on the road. But with some persistence, creativity, and a lot of hard work, you have done a great job to keep yours going. And to quote that great TV sage, Roseanne Roseannadanna, "It's always something............" Now, it is a holiday, so go have at least one "cold one" 😉

    1. Did not say that. I said you needed to verify if the readings were correct or not. The dash display is known to be questionable, but only testing will tell you by how much. 2. Both the gauge and red warning light are controlled by the oil pressure sending unit, and the condition of both would be verified or denied by the test is step #1.
  18. JFP in PA
    The gateway is the CAN Bus system module, and it is seeing a signal that it does not recognize or understand. You may need access to a PIWIS system to diagnose the gateway module issue further.
  19. JFP in PA
    Welcome to RennTech Porsche released an updated oil pump pressure regulating spring and pressure to address this for about $20, plus you can always check the accuracy of the dash display by temporarily connecting a known mechanical gauge; the dash display is not known for its accuracy.

    Welcome to RennTech Just about any AGM battery is an improvement over the flooded cell units that the cars came with due to longer life and no corrosion; but the model you are referring to is lower in CCA and reserve capacity than the model Bosch actually specs for the car, which is the Bosch S6587B S6 Flat Plate AGM Battery.

    When rotating by hand, the hydraulic tensioners and Vario Cam units are relaxed enough to allow the pistons to contact the exhaust valves just enough to bend them if the engine is rotated in the backwards from normal rotation direction. Once that happens, the heads need to come off.
  22. JFP in PA
    Whatever else you do, NEVER rotate one of these engines backwards, even by hand. You will have problems if you do........
  23. JFP in PA
    All of those are band aids to trying to escape the obvious: There are many wrong ways to attempt this, and one correct one. In the end, it is your car and your money.....
  24. JFP in PA
    Sorry, but trying to install a repair device with the head still on the engine is very tricky to nearly impossible. You will be generating a lot of metal filings that simply cannot be allowed to drop into the cylinder bore or they will destroy the cylinder liner. I would not even attempt it in my shop. Your best and safest bet is to pull the head and take it to a machine shop where it can be done properly and safely. Good luck.
  25. JFP in PA
    Welcome to RennTech There is a central locking/immobilizer controller mounted under the driver's seat and is prone to issues. I would start by pulling the unit, opening it up and looking for signs of corrosion or burnt components. These units can often be cleaned and repaired, which is good because replacing it is expensive and time consuming. Good luck.....
