- What weight, type of oil are you using?
- What is the general climate in your area, temp wise?
- How many miles on the motor?
If I remember right blue smoke usually means a too rich mixture, black = oil getting past the rings/valve guides.
Without anything else to go on I'll surmise you need to have your rings replaced. Before you get too worried get a wet/dry compression test to see where you stand.

Blue is dino oil. Mobil1 does not make much visible smoke. Rich is black. A valve job will fix the problem or not. If a valve job does not fix it, a cylinder bore, fresh pistons and rings will help.

Agree. Carbon build up in the valves and head. Try sea foam or some other product that will break up the carbon. Black is also a rich fuel mix IIRC.
