Smoking Engine

I have a F-250 with an inline 6 cyl and at idle there is a substantial amount of smoke coming from the oil dipstick tube and the oil fill hole on the valve cover. I need to find out what is causing this and how to fix it. I don't understand why it would be coming from both when they are on opposite ends of the engine.

This truck is also running very rich you can smell it in the exhaust and it is lacking power. I did notice that a sensor on the intake manifold behind the alternator is broken. Does anyone know the name of this sensor or what it does so I can replace it? I am hoping that it might solve my air/fuel mixture problem.

I just recently bought this truck but have had ford trucks my whole driving career but these are new problems for me. Thanks in advance for any help.

You probably have a clogged PCV. Pick up a new one and that should relieve the pressure.

I dont think thats it, there is so much flow thats I had to disconnect the breather hose that goes from the PCV to the intake because it was blowing oil into the intake

If it isent the PVC then you may have a broken Piston. do a compression test and then you will know.

Check the codes to find out about that broken sensor. If the engine is running overly rich, the fuel can wash the cylinder walls of oil and allow blowby. However, I'm not sure that it will allow that much blowby, so let us know the results of the compression test.
