My 5.9 Magnum Build - Junk Yard Mule

well, I'll start with #8 plug. Typical for them to loose the plenum gasket underneath the intake. Oil enters cylinder, and usually number 8 is the first to receive it.
I totally forgot about the plenum gasket deal. I will check under that intake. Even though I am using a dual plane Mopar Carp intake on my build, I would like to know what caused the things I am seeing.
