2000 S with 74K miles. Use synthetic oil changed at 5K miles. Just replaced my IMSB with LN dual row ceramic bearing! My clutch was on the way out anyway... Horrendous cost but the added peace of mind takes some sting out!
I forgot to note that we found minor metal indications in the oil filter. Plus after the IMSB was removed you could feel roughness when rotating it. Thankfully we caught it early!
