Just a random pulling of the PCV valve led to finding this, glcol in the
oil.. The
oil on the dipstick never showed signs of contamination either, perfect color. I tore it down this morning and first signs indicate that the leak is an intake manifold porosity issue. Ya gotta love Dove. All gasket imprints/contact were perfect, 100% even compression with no gasket stretch/creep or signs of leakage. There's is an area on the intake that's very suspect. A pressure test will tell the tail. I'll provide updates as it unfolds..
...sure does take the fun out of one's weekend..
