    Ah i c. You may feel differently once you start tearing into the AOS. It's anything but accessible :)
  2. Ahsai
    Makes sense. Yes, m96 is quite easy to work on. You said you have already addressed the AOS. Does that mean the new AOS is leaking?
  3. Ahsai
    The pic definitely shows a 3.6 engine.
  4. Ahsai
    You mentioned it's a '01 but it has the MK II style AOS in your pic. Has the engine been replaced at some point in time and is it a 3.6L?
  5. Ahsai
    Glad you found the culprit!
  6. Ahsai
    Some pic of aos leak here http://rennlist.com/forums/996-forum/594986-oil-leak-driver-s-side-not-rms.html Another potential source is the variocam solenoid seal but that should create more stain on the valve cover.
  7. Ahsai
    I see now. It's unlikely the leak is from the head gasket though. I suspect it's from the AOS or its hoses then.
  8. Ahsai
    I think it would be the best if you can check with the shop and see if you should tow it to them to take a look. Also you mentioned head gasket, did you really mean that or you meant the cam cover gasket? Note there's no cam cover gasket. The cam cover to head surface is sealed by sealant.
  9. Ahsai
    The green plugs would have been my guess too. Can you look up and locate the highest point of the oil leak? In a typical ims job, the cam cover should not be disturbed. Can you ask the shop if they have touched the cam cover?
  10. Ahsai
    Yeah, that's what I tend to believe now. Won't be sure unless I remove the regulator and inspect it. I don't think I have any problem like you alluded to. I'm just curious because the soft start I saw (e.g,. on BMWs) is more like 10s+ delay and not just 4s.
  11. Ahsai
    Looks like stock and even original to me. This is the best pic I have. Let me check with the previous owner for more info. Thanks, John.

    '02 996. Alternator does not start charging until ~4 seconds after the engine fired up. Warm or cold, SAI pump running or not. Makes no difference. Once it starts charging, it stays at good level 13.5~14.1v whenever the engine is running. Drive belt is not slipping. No warning lights or CEL. No codes from Durametric. I noticed this behavior on the voltmeter in the dash and also verified the same from the cigarette lighter. I know that some Bosch alternators have a soft-start feature where charging will be delayed up to 14s (to reduce alternator load impact immediately after start up) but AFAIK, our stock alternators don't have such fancy feature. I wonder if the regulator was replaced with one having such feature. Other than that I can't explain it. Anyone experienced this?
  13. Ahsai
    I strongly prefer the OE hard lines because they are light, strong, and take up much less space than the soft stuff. Check out this thread (for a 996, no Boxster but same principle) http://rennlist.com/forums/996-forum/849770-mkii-996-vacuum-line-routing-and-related-components.html
  14. Ahsai
    It sounds like your valve is operating correctly. There is a one way valve inside that releases pressure if positive pressure is applied. Normally the valve only sees vacuum.
  15. Ahsai
    Glad you got it sorted! You can remove the serpentine belt and spin all the pulleys (including the alternator, power steering pump and a/c compressor) by hand to feel for roughness and listen for noise.
  16. Ahsai
    Yes, I used these EWK tool sets to rebuild my m96.03 https://www.amazon.com/Porsche-Camshaft-Alignment-Timing-Tool/dp/B00L0ZYKRI https://www.amazon.com/Porsche-Boxster-Engine-Timing-Camshaft/dp/B00L0ZOZ0A

    Actually now listening to the clips on my laptop, I'm not as sure. Sorry i watched it before using my cellphone. One way to check is to disconnect that valve while the engine is running and see if the noise goes away. The valve is here in this post and there's an electrical connector right behind it on it's right.
  18. Ahsai
    It's the evap regeneration valve clicking doing its job. Nothing to worry about :)
  19. Ahsai
    You can just clean the bolt with brake cleaner and apply some antiseize.
  20. Ahsai
    Some good info and pics in this thread.
  21. Ahsai
    One will have to get to those valves and apply vacuum and/or power to test them to see if one can blow through the valves.
  22. Ahsai
    Then it could be the changeover valve, the vacuum activated valve and the one-way valve. Also sometimes a leaky vacuum reservoir could also be the culprit. Further diagnosis is needed for sure. I guess you just have to choose between spending money on diagnostic or use a shot gun method and hoping the problem is fixed. I don't know how much labor will be involved tearing into those valves on a Boxster so I can't comment whether it's worth replacing all the components in case another part fails down the road.
  23. Ahsai
    Could it be just a burnt bulb? Does the bulb ever light up?
  24. Ahsai
    Sure and welcome to Renntech! The pump is very accessible on a 996 (left side of engine bay with lots of room to work on) and the replacement should be very obvious once you look at it. I say ~1hr for a first timer. It would be good if you can bench test the used pump and make sure it's running well with no whining before you spend the effort to install it. Yes, no problem keep driving the car. The noise is just annoying but it won't hurt the engine.
  25. Ahsai
    It's your SAI pump. Either remove it and relube the bearing or get a used/new unit. New Bosch ones are like $250 each.
