2000 2.7 the 64,000 miles with original IMS bearing. I will only replace when the clutch needs replacing or if signs of metal particles show up on oil changes. It has a Dec. 98 engine build date so it is almost assuredly a dual-row bearing. Oil changes every 4-5K miles with, originally Mobli1 0W40and most recently Castrol Edge SPT 5W40. I have a magnetic drain plug and I cut filters open after each change for inspection - no signs of problems to date.
