mine has been a garage queen in California until it was recently shipped to the UK, I am now taking it to where I live in Spain where it will have a regular thrashing. I will get the ims done on the first clutch change. thanks for the replies folks.

And probably 90% of owners don't forum. That would be even a smaller percent.

I have a 1998 driven at a spirited pace for 34,000 miles with the oil changed yearly. Not sure what to do, but strongly consider replacing the IMS. What comments has Porsche made about this issue? Any additional thoughts / suggestions from the forum ?

I think there is some truth to the frequency the car is driven, more thzn the miles put on it. I try to drive my car several times per week all year. It never sits for more thsn a week not driven. I dont think it matters that you put 20k on it in one yr if it sits for 1-3 months. I think the key is constant use and lubrication of the engine.

But keep in mind that this is a SEALED bearing (what a terrible idea!). Some do speculate that as the seals fail and the grease drains away that oil sloshing can possibly lube the bearing, so who knows.
I'm in the same situation with an '01 at 47,000 mi. Anything can happen. Best situation would be the need to replace a clutch and get the IMS done at the same time.

I have a 2000 Base with 56,000 miles (91,00 km) and the original clutch. The car was meticulously maintained, with oil changes every 3 - 4k miles and stored winters. This winter I am replacing the clutch (although there are no signs of problems), installing a ceramic bearing and replacing the oil separator and serpentine belt and likely the water pump (as another preventative measure). I am also intending to drive the car in the winter when the roads are dry.

Overkill? Perhaps. I don't lose sleep over the IMS bearing; however, I do find myself listening for the dreaded death rattle and any other unusual noises each time I drive the car. For me it will be worth the peace of mind. In addition, we must also bear in mind that most prospective purchasers of used Boxsters will at least do a quick check on the net for reliability/issues and what are they apt to find? You've got it, nightmare stories about the IMS bearing. I have little doubt that the resale value will increase (as well as ease of sale) for any car that has been upgraded. Indeed, I would be suprised if it is not equal to the cost of the bearing and the additional labour invovled over and above that of a clutch replacement (which should also assist in resale).

That's a very good point. Providing that I was an educated buyer at the time, I'd be willing to pay an extra $2K for a new clutch and bearing. That really reduces the overall cost of the upgrade.

If my IMS goes in this motor I will be going with a subi motor. Let the flaming begin.

2.5 Turbo out of an STI? I'd love to see that! I'd even contribute some cash to see that done!

Been done and here is the full story...a good read to say the least from a member on the forum (KCPAZ): http://986forum.com/forums/general-discussions/25697-boxster-subaru-conversion-interest.html

Thank You for the link! I'm finding treasures on this board every time I'm here.

That is an amazing piece of automotive art.

That is who I would get the parts from to make it all happen.
