If it is the RMS, then you should replace the IMS at the same time with an aftermarket one.

If it is the IMS, more diagnostics are in order. Check the oil filter and the oil sump for metal debris. If you find metal, then I'd recommend walking away. It the IMS is failing, it's a crap shoot whether the engine will survive a long time without a complete rebuild because metal will be scattered throughout. Many frequent oil changes after the replacement might help but you just never know.

If you do buy the car, have an IMS experienced shop do the work.

Up through MY05, clutch, IMS and RMS costs about $2500 to $3500 depending on local rates. Ten hours or so of labor plus parts.

How can you tell which one is leaking?
Unfortunately, this car is not within my driving distance and I rely on owner's honesty and his expertise.

I'm debating if I should take a chance and fly there (SF), have it checked at the shop, and then make a decision.

The only way I know is to remove the transmission and visually inspect the seal and bearing flange.

A check of the oil filter and sump for metal debris is an indirect way to see if the bearing is starting to fail. Another way is to look at the camshaft deviations when the engine is warmed up. They should be absolutely rock steady and within +/- 6 degrees.
