  1. Loren receiving the codes (and quite quickly too I may add ... ) make the annual membership more than a bargain!! 

    And what a great sound system Porsche has included in these amazing cars.

    Thank you once again Sir!


    Can't wait to get it on the road (any day now), doubt I'll be listening to the radio much for the first little while : )




  2. Thanks Ahsai, useful data.

    Having an idea of the weights will help in this calculations.


    Sadly I have an overhead crane most shop would envy but not being able to use it for this pull ...

    This car is now pulling me to put a two post lift in the shop...


    BTW, that's a nice clean engine you have there!!  ... just received my IMS Solution today!



  3. Hello all,


    I am in the process of dropping the Engine and tiptronic transmission assembly.

    A thought came to mind for a mooring device than will fasten to assembly to my floor jack along with safety straps.


    My question is, where would the optimum balance point be in relation to the safety strap mounting bracket on the engine.

    There is only one permanent IMS Solution (never needs to be replaced), which is to replace the ball bearing assembly with LN Engineering's IMS Solution, an oil fed solid bearing that will out live your engine,  Their ceramic hybrid bearings are now rated for 75K miles.


    Not to mention adding to the resale value ... I will have to agree and consider it money well spent.

    The thought of major engine failure 100s of miles from home, no brain'r.

    Interesting - so 10-12% of all single row engines have had an IMS failure and 2-3% of dual row engines have also?  I've seen references from a "Porsche enthusiast" that you may be getting this from and seem to see that as the accepted failure rate being repeated multiple times. (i.e. 90% survival rate to 90K miles)  If you could help point to the data source(s) you're referencing I would appreciate it.  Nobody is arguing it hasn't happened, however, it's still not clear to me as to why the disparity and demonstrated likelihood.  If you go back to the original question - should one be concerned with getting the IMS bearing retrofit?  To say how "risk tolerant" one might be is better answered by having accurate data by which to make an informed decision.  Unfortunately, when I became aware of the IMSB issue there seemed to be a lot of conflicting and obviously nonsensical information floating around.  Hopefully, given the time lapse, there's better information available?


    First off, if you are the original owner and if you changed the oil every 5-6K miles (less intervals than what Porsche recommends @ 15k) and you have been using top synthetic oil, I suspect you may never have an IMS bearing issue ...

    Stats are great, but as most cars will go through multiple owners, one will rarely know the history of who & how the car was driven as well as how faithful they where at oil changes.


    This '97 Boxster M96 2.5  I recently purchased ran fine with no irregular sounds, no signs that would warrant concern. Probably the best advice on the net for these cars is have the oil pan removed and inspected for peace of mind. If there is a possibility IMS or other related failure, chances are there will be debris in the bottom of the oil pan. As well on my car, the debris had also collected on the screen of the oil pickup spout. Further inspection of the oil filter one could easily see the finer particles within the folds of the filter.


    Yes I could run'r till she drops but at varying cost of replacement engines from 3 to 10K for a used assembly, I'd rather do the bearing along with any other warn parts now, rather than take a chance later on someone else's used engine with surprises. In fact this Body & chassis is so nice, I should price out a crate engine from Porsche but I can just imagine what that may cost!!!  As a do it your'selfer, I am quite enjoying taking this thing apart, but there again I have a warm shop with all the tools, only thing missing is a hoist!


    Attached picture is the debris in the bottom of my oil pan.





  6. Thank you for the clarification!


    That's some handy resources you have there Loren ...


    I considered doing the Porsche Authenticity report, but you quickly learn working on these cars they're not made in China   ; )

    Fact is I'm owner number 9.  I suspect many things have been changed on this car and it's more likely seen it's fair share of services centers.

    The Tiptronic trany is oily whereas the engine is quite clean  : /


    This Boxster is at the point in it's life that it will either be a money pit or a great car for a enthusiast!!

    Hopefully the latter ... having done the majority of my own auto repairs from engine rebuilding to body work (ugh), this car has found a good home!!




  7. 1997 Boxster original California car with 118,000 miles on the odometer.

    Last digits of the VIN#  S625521

    the engine Ser# M96/2065V15144


    Are the last few numbers suppose to match?

    If yes and they are different, any way of finding out more details about this engine?


    The engine sounds good at idle with good balanced exhaust flow & no blow-by from the crank case.

    Thanks to this community I have decided that it should be pulled before seeing another life of pleasure.

    Debris in the bottom of the pan shows eminent IMS failure as well as pieces of plastic from a chain guide or tensioner. 


    Although an electric motor expert, I feel quite comfortable with this project.

    In fact I am very impressed with the engineering gone into these cars! ( Albeit the IMS thing : )

    Jacking this car one sees just how well balanced they are, simply amazing.

    This particular car has absolutely no rust, for me this will be a pleasure to work on!






  8. My summer ride for the last 30 years has been a '63 Pontiac Parisienne convertible with 99,875 original miles. Long overdue for work, it will be taking a rest ...

    In it's place will be a '97 Boxster Tiptronic  with 117000 miles on it. I can say I'm truly looking forward to road trips with this car!!
