  1. I have the halogen version. It seems the only difference between the Carrera and Boxster version is the pattern embossed on the main headlight reflector. The Carrera uses a cross hatch pattern and the Boxster uses strait flute pattern. Why that justifies a 50% increase in the cost of a new OEM headlight escapes me. From what I read Magnetti Marelli manufactures these lights for Hella who makes them for Porsche. You can buy the Magnetti Marelli manufactured product branded as AL (automotive Lighting) for $790 for left and right headlights. But you get the straight flute pattern.
  2. I'm looking to get some non integral amber headlights for my '99 halogen 996. I came across some new OEM 986 boxster halogen headlights made by magnetti marelli as an OEM for Hella and Bosch. I assumed the early 986/996 halogen headlights were the same, (they look identical) but the seller does not indicate they fit a 996. Has anyone done this swap?
  3. I guess I was surprised at the breakdown at 4K miles because redline is supposed to be a premium "real" synthetic oil. My wear metals have been unchanged over the last 20,000 miles so it's not a poor product. But I replaced it with Joe Gibbs since I found it convenient to buy in Amazon. We'll see. But Blackstone made it sound like my engine was harder on oil than a normal 996 engine, maybe I just misunderstood the way they phrased it. Are 996 motors in general tough on oil?
  4. Blackstone just analyzed my oil and noted my engine was shearing my oil down a little, with a viscosity of SUS 78 and the cSt of 15.01. This oil was Redline 5-40 and there was probably 4,000 miles on the oil. Overall the engine has 73,000 miles on it. How or why can an engine shear oil viscosity down?
  5. I don't recall the version, except that it uses the 14mm hex drive which is characteristic of the newest version. Call Suncoast Porsche for the latest part.
  6. Mission accomplished. The good news is replacing the upper tensioner did the trick. No more noisy morning starts. The bad news is the upper tensioner is a ***** to get at. I had to pull the AC compressor all the way out to get access to the tensioner. Then down near the tensioner there are some hoses you need to unbolt and relocate to get the 24mm(?) socket on the old tensioner. The new tensioner uses a 14mm hex head which is much easier, but I didn't have, so trip to NAPA. By far the hardest part is the AC compressor. Its front two bolts are easy, but the back bolt you can't see. I used a mirror to locate it, and it must have taken a half hour to find it. Next time, 5 mins. putting the compressor back in is tricky because you need make sure the back bolt does not slide down and hang up on the engine while you are sliding it back in. I rigged up a piece of wire to hold the bolt up that I could pull out once the compressor was in place. At the same time I replaced the water pump/coolant, replaced the OEM thermostat with a Raby thermostat and installed a new coolant reservoir tank, so I had the motor dropped a couple of inches which helps.
  7. I bought 3 new chain tensioners for my 1999 Cabriolet. The two that are accessible from beneath the car I replaced. I did not replace the upper one because it is under the AC compressor. I understand the AC compressor needs to be moved to access the tensioner and this is accomplished by removing the 3 compressor bolts. But Bentley says you need to remove the power steering pump reservoir too, which looks messy. I suspect you need to remove the reservoir if you are removing the compressor, which I am not. I just need to shift it over. Can anyone speak from been there done that?
  8. I know, old thread. But I have been troubleshooting this rattling for months, it's driving me crazy! Finally, I suspected it might be the centering pins located at the sides of the top. I put some cork gasket material around the centering pin and closed the top. Noise gone. Now I see there is a TSB that covers this problem. I ordered the new pins from sunset per the TSB.
  9. Pretty boring truth be told. Oil tests and filter autopsies come back clean.
  10. Well, we know what "The IMS solution is now"..... And that elusive pressurized oil source was an adapter at the oil filter.
  11. I need to spend a bit more time adjusting mine too. Close enough for now What a procedure! But I think it will help in the future to mark with a sharpie the glass holders' outline on the window before you unbolt the glass from the regulator
  12. I just installed a URO parts regulator I located on eBay last week; $110 and free shipping. The seller was BMA auto parts. The URO parts regulator looked identical to the Porsche part, and so far works the same as the original functioning Porsche regulator. It solved the typical problem where the window does not lower down when you try to close the door, and causes the window to hit the roofline. But I could force the window down if I pushed down on the top of the opened window, then closed the door. A couple of words of caution, 1). if you re connect the battery with the airbag disconnected you will trigger an airbag warning light. I have a durametric so I cleared it. 2). The regulator itself is a flimsy thing with fragile plastic parts. Be careful taking it out of the bag and box, and then again fitting it inside the door cavity. Once it's installed inside the door it's fine. Lastly, these regulators are also used in Boxsters. There is a lower limit stop that needs to be removed from the front track. If you don't remove it the window will not lower down all the way. Normally I enjoy working on my car, but this job sucked.
