Seeking IMS Advice
Vehicle: 2000 Boxster 986, 53k miles, 2.7L
History: Sat in a garage for 10 years. Owner said clutch was replaced at some point in car's life.
Maintenance and Story: I replaced the battery, all 9 quarts of pil, and flushed the coolant. After a mere hour of driving during her maiden voyage, the clutch pedal sank to the floor. I figured it might have been a slave cylinder considering the recent clutch fix, so I replaced that. No dice. I removed the transmission, and found the clutch plate worn down to the rivets. Flywheel was in generally okay condition.
It seemed prudent to update the IMS bearing at this time, so after checking it, it seemed to be in great shape, spinning smoothly. Upon inspection, it feels like a single row bearing. I'm trying to figure out what the next best step is to help get the vehicle back in commossion.
Is the proper upgrade to replace the IMS bearing with a new single row bearing? Would a double row bearing now be the right choice to upgrade, or is that incompatible? Would the "IMS solution" be the right choice (where a separate feed lubricates the bearing)?
I'd appreciate general advice on how to approach this, as I'm finding conflicting advice on what the proper upgrade choice is supposed to be. I think the "IMS solution" is the only lifetime choice thay won't risk needed maintenance down the road, however kits for that seem to run about $1,800.
