quest - thanks again for all your help.

Perhaps you can do the following for me:
1. what was the rationale behind recharging your system at the first place? (no ridicule given, just wanna know why) Is your system running "not-cool"? or you figure that it's about time to service your A/C system given it's age?
When I first bought the car in July 2005 (with 66k on it) the AC seemed to take a while to cool off the first time I used it, and didn't seem to get really cold - but it did work. so the very next day I "recharged" it with one of those cans and a recharge kit. it then seemed to work great. now, the car had been sitting idle for a few months before I bought it - maybe that had something to do with the weak AC? (that is, instead of it being low on refrigerant)?
also, the AC had never been serviced before - I have every receipt/record from the previous owner (and the dealer also has it online) so there was no previous problem with it.

2. if you may, would you plse (to the best of your abilities) take a closer look at the compressor body or near the shaft/pully are for general oily wetness or some kind of oil spray (not very heavy, something as light as sewing machine oil) under pressure?
I will do so tomorrow and report back.

At this point I simply cannot tell you where the fault lies but my suspicion would be ---> (*cause): overfilled A/C lubrication oil, (*consequence): causing oil spray from the shaft seal area into your clutch pack on your A/C pulley)
This will definitely happen if you overfill your A/C system with excess topoff oil.
ahh, I see what you are saying. that does sound logical, and would be consistent with what I have done to the car.

I would also strongly recommend you to go get/borrow a factory service manual for proper gaping of the clutch and alignment before you put it back into good use for servicing A/C compressor is not for faint-of-heart (yours-truely sure wouldn't touch that part with a 10ft pole, been-there,done that in my "naive" years).....
luckily I do have the Nissan FSM for this car with the proper gapping specs.

Alternatively, ask the A/C shop to see if they are experienced in replacing the clutch pack on that particular compressor pump/vehicle of yourss and see how much they charge for. If it's not too much, might as well pass the responsibility/liability to the pros.
yeah that's probably good advice. I'm one of those people who thinks he can do everything himself, and do it right/better than the shops -- but I'll admit AC systems are way beyond my area of skill/expertise. for some reason I just don't trust the local shops to do it right, though.
UPDATE on the R134a oil -- I emailed Interdynamics and they said the oil in the product i used is PAG100. I do believe the calsonic spec is PAG46 -- but at least it's PAG and not POE. so hopefully I don't have sludge in the system from incompatible oils.
