I have a strange situation going on with my truck. I have lots of oil coming out of my filter on the valve cover. ( not the pcv valve. It's the one that goes to air box).
I have ruled out the obvious problems, I think. Here is what I have done.
Changed the pcv valve
Compression test. 150 lbs on every cylinder
Checked for blow by. I have none.
Had Cat. Conv. Checked. They are bad, but probably not clogged.
I know there are many helpful mechanics on here, that's why I'm posting this question. I thought it might be clogged drainbacks?
Any help would be greatly appreciated. Thanks in advance!!
