| 3.0L 2V VULCAN ENGINE – BLUE SMOKE ON START UP |
FORD : | 2004-2008 Ranger |
2004-2008 Ranger vehicles equipped with a 3.0L 2V Vulcan engine may exhibit blue smoke on start up after approximately a 4 hour cold soak.
This may be due to small amounts of oil commonly found in the PCV system collecting in the upper intake manifold PCV channel.
Under certain parking conditions, this oil can be drawn into the combustion chamber, creating momentary blue smoke that may be visible by the customer.
SERVICE PROCEDURE
- Remove the clamp on the PCV tube assembly at the PCV valve.
- Remove the upper intake manifold. Leave the PCV tube assembly attached to the upper intake manifold.
- Remove the clamp on the PCV tube assembly at the upper intake manifold PCV port, and remove the PCV Tube Assembly from the upper intake manifold PCV channel.
- Drain the residual oil from the upper intake manifold PCV channel by holding the PCV channel vertical with the port facing down.
- While holding the upper intake manifold in the vertical position, spray Brake Cleaner into the PCV channel. Use regulated compressed air to aid in drying the PCV channel.
- Lubricate the O-Ring at the end of the new PCV Tube Assembly with water or diluted soapy water solution.
- Install the new PCV Tube Assembly into the clean upper intake manifold PCV channel.
