DESCRIPTION
Some 2004-2007 B-Series vehicles equipped with a 3.0L engine may exhibit blue smoke on start up after approximately a 4 hour cold soak. This may be due to small amounts of oil collecting in the upper intake manifold PCV channel. Under certain parking conditions, this oil can be drawn into the combustion chamber on start up, creating some blue smoke.
Customers having this concern should have their vehicle repaired using the following repair procedure.
