  1. The recommended way of filling these cars with coolant is under vacuum, it is the way the dealer and any well equipped shop would do it specifically because of these issues. I would suggest shortcutting all the top off and run it folderol and take it to someone with a Uview vacuum filling system; once connected, it will all be over in about 5 min.
  2. Correct, it is warm water returning from the radiators.
  3. Let's just say it is not the most common approach, but it does work well when everything is up to snuff.
  4. According to Porsche's parts system, you should be a 996-618-605-00 (2001, 2.7L, manual trans). The ME7.2 is the firmware inside the box.
  5. If it is a 2001 2.7L, it should use an ME 7.2 DME, but that DME must match the immobilizer and keys, all of which must be coded together.
  6. Welcome to RennTech The DME, immobilizer, and keys all have to match (come from a single vehicle), or be recoded by a dealer to match. The DME version also has to match the original chassis as they changed with model years. What year is the vehicle?
  7. Be careful with the Harbor Freight fuel pressure tester, it is NOT designed for the pressures your DFI runs at, which can be as high as 3,000 PSIG
  8. This should help, it shows how the coolant flows in your car (red is hot out, blue cool returning):
  9. Sounds like trapped air. Fastest way to correct this is to pull a vacuum above the coolant in the surge tank and get the air out, or open the coolant vent valve and "burp" the system.
  10. That does not look like the factory PSE, which should look like this:
  11. Not necessarily, it all depends upon how bad the rings are. A good leak down across the board would eliminate any engine issues and tell you the oil problem lies elsewhere; the question then becomes where. Easiest way to look at the turbo is to disconnect the intake side, looking for evidence of oil and check the turbo's shaft for movement side to side; there should be no play. People seem to forget the turbo's are pressure lubricated by engine oil, and if the shaft develops play, oil will leak towards the intake side due to the presence of intake vacuum on that side. If it is leaking oil, it needs to be replaced or rebuilt. A new one is going to run $3k from the dealer, or you could check locally and see who rebuilds them in your area. As you are in Jake Raby's backyard, I would call his shop and ask who they use.
  12. Welcome to RennTech The engine compartment blower fan may have gotten something stuck in the fan, which can make one Hell of din. No true factory PSE drones, period. If a PSE is installed without all the controls, the default position is open or loud. Takes some pictures and post them, I'm willing to bet it is a cheap aftermarket unit.
  13. You could start with a leak down test to check the sealing condition of the rings. You could also take a peek at the turbo to see if it has oil inside of it on the intake side.
  14. You’ve answered your own question: You unplugged the device and the drain went away; it is the device. As for living under the thumb of the insurance company, that is your call.........
  15. Welcome to RennTech There are four sensors, two ahead of the three way cats, two behind them. P1275 is for the sensor ahead of the three way cat on bank 1, and says it is aging out.
  16. Porsche never published any information about rebuilding these engines as they did not want that done in the field. Jake Raby runs online and in person schools on the subject, and is the only source for printed material on the required torque specs, etc.
  17. Sure: Throw away the insurance device. Besides killing your battery, anytime you drive the car anywhere near like it was meant to be driven, they will raise your rates because you over accelerated, over braked, or cornered too quickly. These things are "big brother" in action...…….
  18. Not necessarily; check your crank position sensor. When the CPS stops registering rotation, the DME shuts off the power to the fuel system and the ignition because it thinks the engine is not turning. And a bad CPS will not always throw codes.
  19. Appears to be L/s squared, or liter per second squared, which would be a volumetric measurement.
