Good Day,
My question is, in the valley below the intake manifold where the knock sensor is located was full of oil. should oil be their , and what would cause this to happen? I'm sending you a picture of this.
Thank you for your time and GOD bless you all in JESUS name a-men!

nope, engine oil should definitely not be there.. make certain the PCV lines are connected to valve covers and also check the oil pressure sending unit to make sure oil isn't leaking from there.

bluelightnin6 Both P.C.V hose are correct. Where is the oil sending unit located , and why would that fill the valley up with oil? What is the unit in the center of the valley in the picture I sent you

BlueLightnin6. Thank you for all your help. I didn't check to see if the sending unit was tight before I asked this question. Hopefully this is the problem. A
