  1. The vent valve is rarely involved as when it fails, it tends to shut off or reduce vacuum flow to the crankcase. As they are cheap, if you were to take it out to check it, I would just can in and put in a new one. And by-the-by, it is not at all unusual to have short lived AOS units, particularly if they are non factory. We have had exactly zero luck with aftermarket units and now only use factory.
  2. Does the car have HID or halogen lights? It is also useful if you post the year and model.
  3. You need to loosen up the other bolts and jiggle the engine around a bit while supporting it until the last bolt can be started.
  4. There are no "matching" engine numbers per se on these cars, The engine numbers tell you the type and year of production, but are not matched to a chassis.
  5. Welcome to RennTech The value of the engines would be with a shop that rebuilds them, depending upon condition, etc. You can try contacting Jake Raby at FlatSix Innovations down in Cleveland GA 706.865.1963 Jake is one of the leading engine builders and buys dead engines for cores.
  6. If it were in my shop, I'd drop the engine. It becomes overly complicated to try and do this in the car, and you can do a quicker and cleaner job out of the car on a stand.
  7. Don't overly downplay the issue, failing AOS units have claimed engines by suddenly catastrophically failing, allow the engine to suddenly inhale liquid oil and hydraulically lock, reducing the engine to rubble.
  8. Welcome to RennTech If your battery ran down because it was not connected to a proper battery maintainer over the winter, the battery may be too sulfated to recover, which is why the static voltage is low. Questionable batteries cause all sorts of weird electrical problems in these cars.
  9. The SAI system is notorious for this "fail" problem. As you have a Porsche diagnostic tool, the first thing to try is activation of the SAI pump using the diagnostic tool. If it does run, you need to start checking all of the valves in the system as one may be stuck or inoperative. This system is always a bit of an "Easter Egg hunt" when they act up. I would also think that your refueling issue may not be related to the SAI fail. but caused by a issue in the EVAP tank venting system, which again is a common problem area. Both of these areas have been written up previously, so I would start with a cup of coffee and a search for some info.
  10. AOS problems do happen after a car has been siting for a bit, we see it often in cars coming out of winter hibernation. The key diagnostic is the crankcase vacuum level. we use a digital manometer to test: On cold start, you should see a value between 4 and 7 inches of water, but warmed up, it should be no more than 5 inches of water. If it is over 5 inches, time for a new AOS, and do not buy an aftermarket unit, we had absolutely no luck with them. Stay with factory. You can find one of these incredibly accurate manometers on Amazon for less than $40, the rest is rubber tubing and a used oil cap.
  11. With the cams mechanically where they are supposed to be, the problem has to lie with the system that reads the position or interprets the deviation values: Cam position sensor, crank position sensor (used as a reference in the process), wiring, or the DME.
  12. A five chain will have one slot on the exhaust side cam.
  13. Let's start with the basics, cam deviation values on these engine's are +/- 6 degrees, so obviously you have a problem. Before disassembling anything, I would hand rotate the engine to TDC and pin the crank pulley, and then pull the cam plugs on bank 1 and check the cam slot position(s) (you did not include the year of the engine, so I don't know if it is a 3 or 5 chain engine, so I don't know if you have one or two slots). At this point, you have basically put the engine in the starting position for an IMS swap, so the IMS cam locking tool should slip right in; if the cam slots are not in the correct position to accomplish this, the cam is out of time and needs to be reset. Good luck.
  14. Anytime, that is what we are here for.
  15. You are OK to drive the car with the console apart.
