    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.

    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    As these cars age, and parts become superseded or no longer available, it becomes increasingly difficult to keep them on the road.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.
  5. 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.

    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.
  9. JFP in PA
    Whatever else you do, NEVER rotate one of these engines backwards, even by hand. You will have problems if you do........

    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.....

    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.

    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.....
  13. JFP in PA
    On second thought, I would suggest you contact LN about your idea of a short-term engine assembly, it may be more complicated than you thought. You may also be correct about the honing due to the plated surface.
  14. JFP in PA
    Good luck.

    The window drop range in these cars is built into the central locking/immobilizer system software and I am not aware of any way to reprogram it.
  16. JFP in PA
    If the rings are going back into the bore they came out of, so that the used rings match how oval the cylinder walls are, possibly; otherwise, you need to hone and re ring it with new rings.

    Welcome to RennTech The information you seek is in the owner's manual for the car, but in essence you push the window button down until the window is all the way down and then hold it for a moment. Then push the up button until the window is all the way up and then hold it for just a moment.

    I believe the Habor Freight jack you mentioned can tilt somewhat, but I don't know how much as I have never used one. The engine is also going to be slanted downward slightly when you pull the gear box, so being exactly level is not critical.
  19. JFP in PA
    Going to be very tight at that height; while we normally work on a lift, if pressed to do it on jack stands, I would like to see 22-24 inches. You are also going to need to support the engine while the gear box is out with either a support bar or screw type jack stand with a hockey puck on top to protect the engine case. I have helped friends do this on stands using what are called Lift bars that lock into the cars lift points and 6 ton stands which can get the car safely up high: Shown here under a 986 Boxster: Engine support bar: Screw type jack stand to support engine:

    Welcome to RennTech I would say it is unlikely you had the chain bunched, but you now need to be very careful and recheck everything according to the service manual procedures. Most people do not realize you and actually damage the valve train rotating these engines by hand if the timing is far enough off.

    Cleaning the flywheel is fine as long as it is not cracked and otherwise OK, and passes the spring back elastomer tests: Tech bulletin on how to test DMF Just do not attempt to resurface it, that will kill the dual mass function and make it worthless.

    If you are trying to remove the wires, you will need a metric pin extraction tool set:
  23. JFP in PA
    You only need to drop the trans to do this job, but you will need to support the engine during the process. On a lift, we use a pole jack with a hockey puck on top to do the job, on jack stands you will need a smaller version, and there are aftermarket engine support bars available that will accomplish the same goal. Changing the AOS is an excellent idea, it will never be as accessible as it is when the trans is out. I would also strongly recommend doing the RMS while you are in there. You will also need all new fasteners for the clutch and flywheel as the factory are all single use items.
  24. JFP in PA
    I would guess that the valve is directional, most valves you find in the middle of lines tend to be so, we just don’t understand what triggers it into action.
  25. JFP in PA
    Solenoids are electrically operated, but that valve does not look like a solenoid, so I would have to say that either pressure or vacuum causes it to change.
