When my truck idles for a while i get a light blue smoke, more prominent when at elevated idle, anything wrong or normal. Im also running Power Service diesel additive.

Somewhere I heard that is normal because engine isn't at a good operating temperature at idle. These diesel don't do well unless there working (heat), really notice it more when weather is lot colder.
