    Before you recharged the system, did you fully evacuate it to remove any moisture? If you didn't, you need to recover the current gas charge, evacuate it, and then recharge it along with any required PAG oil.

    There are very few rebuild shops for the M96/97 engines, even fewer good ones, due to the lack of credible published internal specs and the incredible number of specialized tooling required and a total lack of oversized bearings for cut cranks. Normally, when the internal and external journal and shell bore diameters are good, the only way that the crank locks up upon assembly is either the crank or the carrier do not align true (one of the other is bent).
  3. JFP in PA
    Something does not make sense here; if the difference between the crank journals micrometer readings and the bearing "cage" internal diameters with the shells installed and torqued to spec is 0.002, there is no way the crank should lock up unless the crank carrier is warped by the new bolts or one of more bearing shells are installed incorrectly. If it does need to be line honed, you should try LN Engineering in Momence, Illinois; they are one of the leading machine shops for these engines.

    I think you may have an alignment issue.
  5. JFP in PA
    I would say you have a electrical connection issue with the switch.

    Welcome to RennTech Couple of thoughts: You cannot just switch air bag control modules without coding them to the car, these modules are used in multiple models, so it has to know what it is dealing with. You really need to get the car scanned with a Porsche specific tool like the PIWIS system, which is also what you need to code modules to the car, and can give you vastly more detail than your global OBD II scanner can, such shorts, open circuits, etc. You also need to be aware that many times air bag codes in these cars are related to seat belt buckle issues (poor contact for electrical circuits).

    Click on PayPal, they should show you that option.
  8. JFP in PA
    Should be, be sure to replace the o-ring seals.

    Heater is directly behind the throttle body (1/2inch) on top of the intake.
  10. JFP in PA
    There will be coolant behind that item.

    Now you know why Loctite exists...........
  13. JFP in PA
    For a 2002 Porsche Boxster S, the fuel pressure at the rail should be around 3.3 to 3.8 bar (47.9 to 55.1 PSI), and the fuel delivery rate should be around 850 cubic centimeters (cc) in 30 seconds. The test port is on the passenger side fuel rail, under cap #7 you will find a Schrader valve :
  14. JFP in PA
    Have you tested the car for fuel pressure and delivery using the test port on the fuel rail? If it has full pressure and delivery rates, the answer would be "no". And, as noted from your first post, you got an "immobilizer not ready" warning..............
  15. JFP in PA
    If the immobilizer is dead, the car will aimlessly turn over and never start; it is your anti theft system. The most common reason these things fail is moisture, but we have seen them with burnt circuit boards as well. Take the box out, open it and look, only then you will know if it can be excluded. And yes, it would be expensive as the part is pricey to begin with and you need access to a PIWIS system to code it to the car.

    8035 Diagnosis information rear - Reversing light Possible fault causes - Open circuit/contact resistance in wiring, sockets, plugs and terminals - Short circuit to ground in wiring - Reverse gear switch faulty - Tiptronic control unit faulty - Short circuit to ground in point SP039_SPRFL_2 (driver's seat) of the ParkAssist control unit

    Reread what Loren posted above: 8035 Diagnosis information rear - Reversing light Possible fault causes - Open circuit/contact resistance in wiring, sockets, plugs and terminals - Short circuit to ground in wiring - Reverse gear switch faulty - Tiptronic control unit faulty - Short circuit to ground in point SP039_SPRFL_2 (driver's seat) of the ParkAssist control unit And please do not double post your problem, it is against forum rules................
  18. JFP in PA
    Welcome to RennTech When the immobilizer is working properly, it sees the engine turning from the crank position sensor signal, turns on the fuel pump, and switches on the ignition circuits. If any one of these are not functional (e.g.: the crank position sensor has no signal output), the immobilizer does not turn on the fuel or ignition as a safety function to prevent a fire. Everything has to work or you get nothing............
  19. JFP in PA
    The immobilizer is not susceptible to sitting, but it is dangerously susceptible to moisture intrusion, which is a common problem with these cars. Here is a video about the problem and how to remove and examine the unit. https://www.youtube.com/watch?v=x9rpTYXSdYc And this is what the internals' look like if they have been wet:
  20. JFP in PA
    At this juncture, I would be looking at the immobilizer, pull it and open the case looking for signs of corrosion or moisture damage. It also has its own small fuse in it, check that as well. It is under the driver's seat.
  21. JFP in PA
    Did you have it coded to the vehicle with a PIWIS system? If not, start there...................
  22. JFP in PA
    Please do not double post your problem in multiple forum sections, it is against forum rules, and you will get an answer when one becomes available.
  23. JFP in PA
    The valve lift system, like the Vario Cam system, are hydraulicly operated using the engine oil pressure network. One of the biggest problems with all of these systems is that they were designed with very small oil passages, making them very susceptible to problems with particles of debris in the oil blocking the passages. The fact that you found debris in the valve lift screen points to where the issue probably lies.

    Welcome to RennTech Nearly all car manufacturers purposely set their speedometers to read slightly fast, usually about 5 MPH, in an attempt to reduce any liability for potential speeding tickets. Some sages have also noted that with the speedo running fast on purpose, your warranty also runs out faster, but there is no evidence supporting that conjecture. As for your "at speed' questions; alignment, uneven tire wear, and worn or loose suspension components' are all candidates. A decent alignment shop should be able to tell you what's up in that department.

    Usually, the internal walls fail in these oil coolers; when an O-ring goes bad, you typically get an external leak of the fluid passing thru that seal due to the internal pressures. Before removing the cooler, you need to drain the cooling system, but not necessarily the oil although many change the oil after servicing the cooler, just to be safe. Four small fasteners hold the cooler in place, and it is a very good idea to lift the cooler slightly before removing it and sliding a plastic bag under it to catch any residual fluids and prevent them from going down the wrong port. That said, if you have pressure tested the cooling system with no pressure loss, it would be my opinion that nothing is leaking, you just have cloudy coolant. Coolant can get cloudy for several reasons, the system was filled with a mix of coolant and tap water, the coolant is old and crapping out, debris in the system from prior repairs, even someone adding the wrong fluid to the coolant tank. You can drain the system, flush it with clear water, and then refill with a 50/50 mix of fresh coolant and distilled water (use distilled because the minerals in tap water reduce the service life of the mix).
