Blue smoke, rings or vlv guides, seals ?

[96ccdd]

I noticed over this past weekend I'm starting to get a little blue smoke from the drivers side exhaust. The motor was at operating temp and had been running for a few hours. What typically goes on the 6.2's, the valve seals like the Small Block Chevy? If so can I just install umbrella seals ? I only use the truck once a month to go wheeling.

Thanks
