I have a freshened up 6.0 with maybe a 1000 miles on it, I have a small amount of white smoke coming out of the oil fill hole on the valve cover. There is no pressure or pulsation out of the oil fill and the smoke lingers slowly out, its not alot of smoke and happens after the motor is warmed up. I have done a compression test have gotten 150-155 in all 8 cylinders. I also have a catch can setup with 10an hose from each valve cover. My question is, could this be normal or is it blow by? What else could cause these symptoms also?

If you have a catch can that has a filter on it, you could be getting condensation under the valve covers when it cools down after driving which is burning off once the engine heats up. It normally doesn't hurt anything.

Yes the catch can has a filter on it. Just hope its not the rings, the compression test was damm near perfect in every hole.

Mine has been doing that for 4 years while spraying the **** out of it every weekend. Runs just like the day it was built. No problems
