My guess is that the direct oil feed bathes an unsealed IMS bearing in more oil than splash oil from the crankcase would. Am I correct and does the testing show that more oil fed to the bearing means less bearing wear?by thom4782 - Main Forum
You can buy a gauge at a parts store and us it to test the pressure on the low pressure side of the system. They are cheap. The parts store gave me one that a customer returned. When testing just keep the valve closed if you don't have a can a refrigerant attached to the other end. If you find the pressure is low, then buy a can of refrigerant that contains dye and refill the system. Don't buy aby thom4782 - Main Forum
I support all who suggest getting an alignment. Do so at the best alignment shop in your area. My 986 had asymmetric rear tire wear on each tire. I brought the car to a high end custom alignment shop in the San Francisco bay area. They adjusted the alignment both front and rear wheels outside the factor limits for some parameters. I cannot remember which. I can tell you, however, I just replaceby thom4782 - Main Forum

When's the unveiling?by thom4782 - Main Forum
My understanding is this. When the OEM bearing seal degrades, splash oil mixes with the OEM lubricant. When this happens, the lubricating properties of both fluids (that is the mixture) degrade so the bearing isn't sufficiently lubricated. And then the bearing fails. The LN bearing isn't sealed or internally lubricated. It's open design allows splash oil to lubricate the bearing properly.by thom4782 - Main Forum
You characterized it correctly - the LN is insurance. The odds are in your favor that the OEM bearing will last another 30K to 50K especially with frequent oil changes. On the other hand, the LN bearing adds about $850 to your tab (labor included). So the trade off is...LN insuarance v. dollar difference between resale and salvage value. If you plan to keep the car for a long time, then buying thby thom4782 - Main Forum
I have not read the Panorama article. My understanding is that the LN Retrofit is NOT a sealed bearing packed in grease. It is unsealed and lubricated by 'splash' oil from the engine. So the failure mechanism described in the quote must be referring to the OEM bearingm, which is sealed, and does fail in the described way. And, if I am correct so far, the the quote 'I believe every one of them wby thom4782 - Main Forum
The IMS Solution uses an oil fed plain bearing whereas the LN Retrofit uses a splash oil lubricated ceramic ball bearing design. Beside price and method of lubrication, the advantage of the IMS solution is that it will not allow the IMS to wobble should the bearing wear of fail. This prevents the timing chains from coming off their sprockets with the resulting engine self destruction. The IMS Solby thom4782 - Main Forum
Marc is correct. I looked up the paperwork and it was 40 degrees outlet temperature from the vents.by thom4782 - Main Forum
IIRC, I got the 60 degree number from the AC shop where I took my car for diagnosis. I have a small leak in my evaporator. When I top off the refrigerant, 60 degrees is also the number I get when testing myself. Perhaps someone has a better number.by thom4782 - Main Forum
If you try Pedro's suggestion, you should feel 60 degree air coming from the vents when the AC is on. You can test this pretty closely using a kitchen meat thermometer. If the system isn't blowing cold air, then mostly likely you have a leak. You can pay a shop to do a vacuum test. If it holds, ask the AC shop to put dye in the system when it refills with refrigerant. I had a good vacuum test, buby thom4782 - Main Forum
Replaced soft window after 10 years. Cost ~ $500 and the shop took 1/2 day to do the work. Works great. Clear and no leaks after 2 years. The trick is to find a shop with a great reputation for quality work. Good luck. PS: My understanding is that the glass top replacements look and work great but they restrict access to the engine compartment b/c the glass top doesn't fold as high in the serviceby thom4782 - Main Forum
While to odds of failure are low, I would toss a spare serpentine belt in the mix. Easy to replace and not worth the down time to locate one on the road. And maybe a spare low and high bean headlight bulb. These are more about avoiding downtime than anything else.by thom4782 - Main Forum
You definitely want to deactivate the passenger side airbag when your pooch is riding in the seat. A guy in England sells a switch that plugs into the socket under the passenger seat that will allow you to do this. See discussion in 986forum. [986forum.com]. Alternatively, you can buy a used bar (and hopefully a child seat buckle) from a dismantler. Oklahoma Foreign sold a set up to me for abouby thom4782 - Main Forum
Porsche serviced many cars during the warranty years for all types of problems including IMS failures. Given this sample size of serviced cars and the percentage of IMS failures, statistics would say that the 'true' failure rate is what Porsche reported to the court. At worst, there may be some uncertainty (+/-%) about the reported rate, but it's likely to be very small (<1%) given the sampleby thom4782 - Main Forum
I misread the original note. My 'spring' part number referred to the one that returns the outside door handle to its closed position. I think Bruce my be referring to a part called a Bowden cable in the parts diagram. It connects the inner door handle to door lock. From the parts diagram I have, the Bowden cable part number is 996 537 320 03. Try looking at the diagram on Auto Atlanta site for thby thom4782 - Main Forum
I believe the rear trunk release cable number is 986 512 017 01. The catalog calls it a tensioner. The return spring from the left side door handle is 996 537 611 00 I'd suggest calling AutohausAZ for opinion on OEM v aftermarket.by thom4782 - Main Forum
After reading the threads and the information provided on the IMS Solution site, I reach the following conclusion (really just a theory). The single or dual row units have multiple wear points. When their ball bearings degrade for whatever reasons, the IMSB starts to spew debris throughout the engine. The damages other parts of the engine sometimes beyond repair. There are few ways to detect anby thom4782 - Main Forum
My indie and I were discussing this point just last week. He's never seen a tensioner related failure in a 986, but the variocam pads and chain rails can wear and lead to a catastrophic failure. This would seem likely in really high mileage engines. At 27K, I wouldn't think its a problem or a concern.by thom4782 - Main Forum
