Ford Ranger blue smoke on startup

How to fix Ford Ranger blue smoke problem

Ford has issued a service bulletin #07-22-10 to address a Ford Ranger blue smoke on startup problem. Ford has identified a problem with oil collecting in the upper intake manifold PCV channel. After a 4-hour cold soak and startup the old can get sucked into the combustion chamber and burn before the catalytic converter has fired up. This results in a puff of blue smoke from the tailpipe. Ford has issued a new PCV hose, part #BL5Z-6C324-A. The issue appears on 2004-2008 Ranger trucks with the 3.0 Vulcan (2-valve) engine only. Purchase the PCV hose connector and hose assembly and follow these installation instructions:

1)      Squeeze and remove the clamp on the PCV tube assembly at the PCV valve.

2)      Next, remove the upper intake manifold, but leave the PCV tube assembly attached to the manifold.

3)      Then remove the clamp on the PCV tube assembly where it connects to the upper intake manifold PCV port. Remove the tube.

4)      Hold the upper intake manifold vertically and spray brake cleaner into the PCV channel to remove any remaining oil. Then dry the channel using compressed air.

5)      Use water and a drop of soap to lubricate the O-ring on the end of the new PCV tube and install it on the cleaned upper intake manifold PCV channel.

6)      Reinstall the upper intake manifold and connect the PCV tube to the PCV valve
