I have oil coming out the dipstick and don't know why. Any suggestions?

 

Couple causes for that are...

1. PCV valve blocked
2. Rings allowing blow-by

Have you performed a compression test on all of the cylinders and check to ensure the PCV valve is working?

 

Pcv valve is OK I have bought a new one. The vacuum line that goes to the breather doesn't have but barely any vacuum so I re-routed it to the tree off the intake. But I am still lossing a lot of oil. Like a qt a day and not burning it at all? I am getting to be at wits end

 

You stated the PCV valve was OK, but what is the vacuum going to it? I have seen the hose plug and no vacuum get to the valve to allow it to work.

 

Are you actually getting a quart of oil out of the dipstick tube? Or are you loosing up to a quart of oil and SOME is coming out of the dipstick tube?

If you have a good WORKING catalytic converter, you normally will not see any smoke from burning oil.

I would put a vacuum gauge between your PCV valve and the vacuum port that it's connected to. Then see what reading your vacuum reading is. Your intake vacuum at idle should be steady between 16 and 22 inches Hg (Mercury).

 

Ok I have really good vac comin off the tree and I have checked the usual places where I might loose some vac pressure I have even taken the dip stick tube out to see if the o rings on it were bad but they r not. It only seems to blow by when drivin while sitting idle the truck doesnt loose any oil
