  1. The AOS, coolant tank and water pump are preventive maintenance items you could ask about.
  2. I am about to replace my clock stem as well so watching this with interest. What device or technique did you use to remove the speaker on the left side of the dash? Mine is really snug and I am concerned about forcing something in to lift it up as I am sure it will scratch the finish.
  3. I changed the clutch on my '04 at 70K miles because I was doing the IMS/RMS thing and it was only about 1/3 worn so would have been good for many more miles. All depends on how it is driven though. I am baffled by the arithmetic on your car. Only 3K miles per year but daily driven? That's 9 miles per day!
  4. PSM was an option. I have a 2004 C2 and the PSM is on the option list. When I was looking for a 2002 or newer 996, PSM was on my options wish list and many of the cars I looked at did not have it. There might be a special model, like maybe a C4S, that has PSM as standard equipment but it is part of a model upgrade package. BTW, you list the VIN as WPOCA.... and I am pretty sure that 3rd character is always zero, not "O".
  5. If someone has the actual mix info, is there a difference between Lapis Blue L3A8 and Lapis Blue M5W9? Apparently the code for Lapis Blue changed MY03 but did the paint color actually change as well? My paint code sticker on my 2004 calls it metallic but I have also seen this later M5W9 referred to as pearl so are they different?
  6. Maybe my "rear plastic plate" is really something originally supplied to support a front plate?? And maybe the washers go along with the plate on the front? Makes more sense than having an extra plate in the rear now that I think about it.
  7. Congrats on completing the job. I did the same. AOS was the hardest part IMO. I used "guide pins" in the block (made from bolts with the heads cut off) to help with the gearbox install. It ensures you are lined up square, which is kind of hard to be sure of when working alone under the car. The fine splines on the input shaft don't help either, as far as getting the thing engaged properly in the clutch disc. I have 1500 miles on my work now with no issues or leaks so I am starting to relax! Best of luck with yours.
  8. On my car, there are two washers like that behind the rear license plate plastic plate. Between the plate and the body. Not sure how one would end up where you found it though? Anyway, another place to look.
  9. So apparently these are actually vacuum lines not fuel lines. I just spent 45 minutes at a Porsche dealer parts counter with no success identifying this item. He suggested I remove the clip and try to find a number molded into it. To do this, I think I need to lower engine for better access. Before I go to this trouble, I am bumping this in hopes of some help with the p/n please.
  10. I want to replace the two plastic fuel line clips on the LH side of the engine compartment (which I partially broke struggling with replacement of the coolant tank). I thought I had these figured out as p/n 999 507 521 40 but these are not correct. I would also appreciate some tips on how these are fastened. There appears to be sort of a plastic pin on the RH side of the clip - how does that come out? (not much room in that area either) It is the clip at the top of this photo that retains the fuel line and some other stuff.
  11. I use one of these to jump the switch. Nice and tidy and easy to do/undo by feel. Not as cheap as a paper clip but handy to have in the glove box just in case.
  12. The mod you are describing is the same as the Fister mod. You can buy modified mufflers from Fister outright or exchange, or it can be done by a muffler shop. Many owners have done this and report satisfaction with the sound. I don't think this is the same as the PSE exhaust routing, which actually has two inlets and one of them bypasses a portion of the muffler internal baffling.
  13. Those are all good suggestions but you don't have to drop the engine to do the IMS/RMS and clutch. I'm sure you know this but didn't want andrewjt19 to think otherwise. Replacing the water pump and serpentine belt would be other items that are worth doing and can be done with the engine in the car. Of course, if you buy a car with complete service records you can make judgement calls on whether it is time to do these PM items or not. Lacking those records, it would be prudent to do as many as you can afford to do soon after purchase to start building a service record for the car and head off potential problems.
  14. I have done the whole enchilada. IMS, RMS. AOS, spin on filter, water pump, coolant tank, serpentine belt, clutch, motor mounts, oil analysis, sump inspection, etc. I think I will just consider my work "done".
  15. Thanks for the input from all this experience and knowledge. I have done a lot of PM work DIY and have been successful with it so I guess I am feeling a little cocky about digging deeper. I think I will just leave well enough alone, as I can't really address all of the possible failure modes without a complete rebuild of what is currently a great running, no issues engine.
