I know that when you do the clutch you should also do the IMS and RMS.

My mechanic says that if the IMS has not failed yet to leave it alone.

This car likely has the double row bearing.

I'm not interested in spending more than I have to so not doing the IMS will save some $$.

Thoughts?
My throughs about this is that if the car is in good shape, is babied, and you intend to keep the car, and adress issues as they arise, i would do it.

I'm going to do the clutch on mine and will do ims and variocam pads at the same time. Variocam pads are surely a wear item and guaranteed to be worn at that milage. Finding brown plastic pieces in the oil filter is a sign they are on the way out.

The real cost here is work, getting the transmission off, and changing clutch. The ims job is pretty quick. Imsb part itself can also be a considerable cost depending on what you change to. If you change to an open bearing, its important to check the oil and oil filter for debris to make sure the engine is in a good state.
