  1. Welcome to RennTech. Could be a couple of things; a fuse is possible, or a weak or failing ignition switch. You are going to need to do some "poking around" diagnostics.
  2. What water pump did you use (brand/impeller material type)?
  3. All these parts have been superseded with upgraded pieces: Piston 997.107.125.01 Spring 996.107.127.53 Gasket 996.107.123.50 So for less than $20 at retail, you get better low RPM oil pressure. The new piston also has a bevel on its upper edge as well, and the spring is slightly longer:
  4. LN make the nicest ones that I have seen, and we have never had any problems with their products.
  5. You might say we have had good results; I have many of my customers on them for several years now with excellent performance. I also use them on my personal fleet as well. One additional benefit ( amongst many) is that you can use a FilterMag with the spin on, so that every drop of oil passes through a strong magnetic field on every pass.
  6. To change the chains, the engine has to come out and apart. So unless you can see a reason to do it, I'd leave them alone. A cam swap could have accelerated the wear pad issue. As you are already there, the solenoid would not be a bad idea.
  7. Welcome to RennTech. As yours is a five chain motor. the likely culprit are the small chain tensioner wear pads between the cams: While not a difficult job, it does require some specific tooling and knowledge of how the cams are times or "allocated" in Porsche speak. I'm pretty sure there is a DIY with photos over on the Pelican site for this specific project, but if you can get access to either the factory service manual or the Bentley 996 manual, you can find everything needed. Good luck.
  8. If you actually have a bad head gasket (which I cannot see in the photos), you would be the very first head gasket I have ever seen fail on one of these engines. By far, the two biggest reasons for intermix on an M96/97 are cracked cylinder heads, or cracked cylinder liners:
  9. Both systems show hours, you need to calculate the miles based upon assumed averages.
  10. The system does not work that way. The security system in the car is coded to match the key and its buttons, which requires having the key codes and access to a PIWIS system to enable the coding. I am unaware of anyone that sells the electronics package that goes into the keys other than buying a new one from Porsche and then having them code the car to match. Aftermarket or used stuff will not work without all the correct code information, and then the car still has to be coded to accept it. Be ready to spend some $ for all this.
  11. Take the battery to an auto parts store and have it load tested; it sounds weak.
  12. It makes absolutely no sense that the car can't hold vacuum but can hold pressure. The vacuum system is the standard method of filling the cooling system without trapping air pockets, and is used by dealers and shops across the world.
  13. Besides reassuring your feelings about the car, a quality retrofit will enhance its resale value as well.
  14. It is running hot. Have you cleaned out the front radiator wells? of debris
  15. No, I mean it happens frequently, and yes, you do need to take it apart to see how badly it has failed and fix it. If left alone, the VarioCam system will fail and you risk jumping time. If you do a search, I'm sure you will find someone's DIY, but be sure to pay attention to the tooling involved and how to reset the cams when you are finished.
  16. Jake is correct, and it is a common problem.
  17. That is going to involve some "hand on" diagnostics, testing the various valves and sensors in the system.
  18. I really wouldn't let the coolant go that long. We check coolant on every car that passes through the shop for pH, freeze point, clarity, and couple other items; generally, 50K miles or 5-6 years seems to be the going limit for most cars.
  19. Welcome to RennTech. The DMTL (Diagnostic Module Tank Leakage) tests the fuel tank and fueling components for leaks by slightly pressurizing the fuel tank and evaporative components. On some cars, like the BMW where this is a common issue, use a small pump to accomplish this test.
  20. Unfortunately, I have no idea what "too big" means. You need to scan the car with a Porsche specific tool, such as the PIWIS or Durametric software. Porsche vehicle's use unique diagnostic logic that often confuses aftermarket diagnostic tools an leads to erroneous codes, and often completely misses real codes as well.
  21. Amazon sells the Airlift system, which is what the dealers use.
  22. Are you sure the cooling system does not have any air pockets in it? Check your radiators for debris that collects and blocks the airflow:
  23. If you really want to scare yourself, add a spin on filter and a FilterMag unit that turns the entire filter housing into a magnet. Magnetic drain plugs see only some of the oil, the filter sees all the oil, all the time; so the first oil change after adding the FilterMag, you see all the fine sludge the car has built up since new:
