Blue Smoke from Exhaust Tail Pipe Step 1 - Sludge can develop inside the engine due to poor maintenance and can plug the oil drain back ports which in turn fills the cylinder head up with oil which then gets fed down through the valve stem seals and into the combustion chamber producing blue smoke. To repair this problem remove the valve cover and clean debris from the drain back holes, reassemble and recheck (Note: After the repair you must wait 2 to 4 days before the remainder of oil on the valve stems to dissipate.)
Crankcase Vent Control System Step 3 - As an engine wears, the piston rings will lose their ability to control oil which will allow it into the combustion chamber to be burnt causing blue smoke from the tailpipe, in this case the engine is worn out and replacement is needed. To confirm this diagnosis remove all spark plugs and inspect, if all plugs have oil on them the confirmation has been achieved, if a single plug is fouled then only one cylinder needs to be fixed.

New Piston Rings Step 4 - Valve stem seals control oil from entering the combustion chamber, if these seals wear out blue smoke will result due to oil entering the combustion chamber, to repair this problem replacing the valve stem seals is necessary. Helpful Information Blue smoke appears mostly at morning start up's. Poorly maintained engines are much more prone to problems such as smoking, preventative maintenance is cheap insurance to ensure that your engine runs as smooth as possible for many miles. If engine replacement is required the best option on a new or rebuilt engine maybe obtained by the dealer, surprisingly costs for the engine (engine only, no labor) is close to what an engine rebuild can cost independently.
