Narrative:

Aircraft arrived with logbook entry #2 engine CSD operating in caution range at cruise power. I looked to see through servicing door to make sure it had oil, which it did, but I was unable to see the level. Due to temperature light never coming on and it was only in caution range with no temperature indicated in logbook, I mco'ed the item so it could be checked out later that night.
