Im burning oil and I get, valve noise or pre ignition sounds, when the motor is hot or going up hill.
I pull the PCV and its very wet with oil. Do you think I have a clogged hose?
I do get some smoke on start up but its not too blue and its not too much.

I am wondering if you have sludge? Also what grade of fuel are you burning...Pre ignition is not normal if running 91 octane, however with the ethonal blend fuels it could be.....
