Saga over with decision made on 3 final repair options... -------------------------------------------------------------------------------- Jim Ellis Atlanta Dealer did try really real hard to assist....final options: 1) Replace the IMS seal and pay for RMS seal. Dealer pays for everything else via Porsche. Car out of warranty 3 months, so Porsche NA and dealer did something - about $ 1,000 in repairs. 2 year warranty on the RMS and IMS seals, since I paid something for leak repair per their rules. Case specs were good. no major engine disassembly a plus...at least most of the bolts still twisted in by German factory..... 2) Buy aftermarket heavy duty bearing, no warranty and slip on to the existing IM Shaft, no major teardown. 3) Replace IMshaft with new upgraded Porsche IM shaft and bearing and receive 50 % off labor and 2 year warranty on lower end of engine and bascially resealed motor.....bill to be around $ 2,000 in total and take preventative risk of no more failures. have to do major engine teardown, good confidence in techs, but you never know......maybe other issues later...car runs great now..... decision - # 1 ......75,000 mile car, 6 years old, worth 30 on trade max, low 40's retail.......take risk IMS original bearing holds up...........I will keep as my second 911 and daily driver, have 993 - 1995 cab with 37k miles in great shape..........wife said buy a new car to put a better smile on my face....maybe Maserati 4 door, Bentley or Aston 2 door....Panamera too ugly in and out for me......
I asked them to check the case specs and they are okay for this engine.......bearing and shaft have been recently upgraded so changing just the bearing no longer an option.....now seeing if Porsche will replace the shaft and bearing as a result at no charge due to acknowledgement that part needed to be upgraded for durability reasons.........we'll see....car in shop for 4 days now......
larez2: The Intermediate Shaft itself is not the part that fails. It's usually the bearing itself or the support stud that give out. Replacing just the bearing and support stud (and the flange) does not require engine teardown in a motor with the single-row bearing. I don't believe there is any advantage to replacing the Intermediate Shaft itself, as that is not where the problem lies. Regards, Maurice. I found out today in new development that Porsche upgraded the shaft and the bearing that they sell as one part, so I can't just change out the old bearing...for a new one......they are going to try to see if the whole job can be covered due to this acknowledgement that the part needed an upgrade......car is 2003 C4S..........
Thanks for the advice given in the trail of posts!! You might want to consider the IMS retrofit kit from LN Engineering. I believe it costs about $600 and it is claimed to be a much more severe duty bearing, along with a beefier flange and support stud. Do some reading here: http://www.lnengineering.com/ims.html before you make a decision. Not sure about the warranty they provide if that's your main concern. Regards, Maurice. Thanks agin for the advice.....good one.....Andy B...
Well......my warranty runs out a month ago and the dreaded Rear Main Seal /Intermediate Shaft Seal leak occurs again at 74,000 miles........happened previously at 60k and 68k......... called Porsche North america and sent them 26 pages of service records on the car......they came through and paid for the labor and parts 100% for replacement of the IMS seal which was the culprit...... the upgraded RMS that was in there was okay, but I am paying for a new RMS seal to secure a 2 year warranty....warranty not available on out of warranty car unless I spend something as an owner expensed item related to a repair like this...... no additional warranty on free work on out of warranty car....funky rule... The dealer recommended that I replace the bearing on the Intermediate Shaft, which is sold together with the IMShaft for $800.....and can't be bought separately....they will use the new bearing on the old shaft and we hope that fixes the issues once and for all.....I will have a new shaft for an expensive paperweight.........anyone else have a similar experience with the IMShaft bearing replacement, etc....?? The dealer feels that replacing the bearing will be a preventative measure in having a potential IMShaft failure that would be more critical and would cost about $ 5k in repairs versus paying approx. $ 700 after discount for the preventative repair now... any opinions on this course of action???
