    More common that Porsche, and some other Boxster websites, would like to admit. There is an aftermarket replacement bearing assembly designed to reduce the probability of it reoccurring (recently written up in Excellence magazine) which many have had great success with, and some nay-sayers claim is pure commercial "clap trap". Read up on the subject.................
  2. JFP in PA
    Sorry, but it has all the indicators of an IMS failure (rear bearing on the intermediate shaft fails, cam chains lose tension, one or more cams jump time, valves make contact with pistons, instant boat anchor). Usually, this requires either a new engine, or an extensive rebuild............
  3. JFP in PA
    Actually, a far more useful suggestion would be to buy a quality battery maintainer and use it when the car is going to sit…………
  4. JFP in PA
    This is done using a PIWIS unit, which tells the DME (amongst other things) to ignore the second O2 sensors (a traditional "fix" for the CEL on US cars that run headers without the second sensor). I am not aware of any other system that can correctly change this..................... I've seen multiple cars in the shop that have had this done, none exhibited the issues you mention.
  5. JFP in PA
    Yes............
  6. JFP in PA
    No, I don't have the part numbers, but they were OEM parts and the kit instructions said it would fit either a base or S 986. That is why I wondered why you had sizing issues.............
  7. JFP in PA
    Steve, I'm not sure what size issue you are referring to; I've done a couple of these using kits from Suncoast that came with the correct hoses, and everything fit fine...........

    Possibly one or more of the chain tensioners bleeding down. Often goes away by switching to a slightly heavier oil, like Castrol Syntec 10W-40. If heavier oil does not help, it will need more significant mechanical help……..

    Flow is outside to inside..................
  10. JFP in PA
    If it adds a vibration dampener (lacking in the OEM due to internal balancing), it would help prevent harmonics that can cause rotating part failures.
  11. JFP in PA
    When the engine is running, the oil pressure is always higher than the pressure in the cooling system (~60 PSIG vs 18 PSIG), so if a crack or other route (e.g.: blown gaskets) for the oil to leak is there, the oil would have a natural tendancy to enter the cooling system.
  12. JFP in PA
    OK, you are dealing with the dreaded IMS. If the shop is a dealer, I have to assume they know the correct procedures to do this. Yes, there is an LN bearing that will fit, and it is a much better unit than the OEM.
  13. JFP in PA
    Is this what you are refering to? And if so, how did you get from the water pump on the front of the engine to the rear without the flywheel? If this is it, it is the IMS bearing assembly, which can be replaced without having to rebuild the engine, unless the engine has "jumped time" and bent all the valves................. Also, is the shop doing the work a Porsche shop? Reason for asking is that before you remove that triangular cover, the engine needs to be locked at TDC and the cams locked in position using special tooling to prevent the engine jumping time. The engine may be just fine, but pulling apart the IMS is not something that should be tackled by a shop without considerable experience as well a the correct tools.
  14. JFP in PA
    It does, but I'd still like you to answer my questions from above............... something ain't right here...........
  15. JFP in PA
    I'm a little confused here, what "wire around the bearing" ("When they got to the leaky gasket, they were face to face with the bearing. The cover had already broken off and was missing, and they showed me the amount of play and rattle in the bearing, and how the wire around the bearing was all bent")are you refering to???
  16. JFP in PA
    1. No, not necessarily. 2. Yes, uncover the tank, make sure it is full the mid level and put a pressure tester on it. 3. Depends, could be green (early) or pink/amber (later). They are both compatible.
  17. JFP in PA
    If you are really interested in the belt tension, there is a $200 tool that measures it by the amount of belt deflection...............
  18. JFP in PA
    Just wondered how you changed your condenser or got access ,as I have to change the left condenser on my 987 boxster. I think I have to remove the front bumber cover and the air intake. Any thoughts if you have done this. peter The front bumper cover has to come off..................
  19. JFP in PA
    You are kidding, right? At least I hope you are kidding.......................
  20. JFP in PA
    You need a new tank; when you order it, also get the latest cap (ends in either -03 or -04) as well..................
  21. JFP in PA
    Most likely either a bad cap or a cracked coolant tank....................
  22. JFP in PA
    Or you can get a complete kit from Yellow Dog Motorsports and have in installed in 5 min................

    Most likely, it is one of the axel assemblies. For some reason, a lot of shops do not properly clean, Loctite, and torque the axel flange bolts; and they back out, killing the drive. Usually, fresh bolts, Loctite and re-torque is all that is needed, as long the flailing axel didn’t hit anything important…………

    Yes, we use Stant pressure testers in the shop just about every day. You will need to obtain the correct adaptor for a Porsche, but the Stant system will work with anything........ Thanks JFP. I was just looking at the Craftsman tester. It has 8 adapters. Does the car have to be running? Because the coolant leaks on one of the pulleys and ends up all over the place, making it hard to spot the leak. Thank you. Mike No, the car does not have to be running. You can also add a UV dye that will show where the leaks are as well. As for the Craftsman unit, we use Stant becuase the make adaptors for anything which you can add as you need them; sets that come with a cluster of "most popular" adaptors usually don't make sense because you end up with a bunch of stuff you never use..............
