1--Though I am getting vacuum from the PCV valve into the forward portion of the valve cover , I can not feel the vacuun at the rear of the valve cover where the grommet/hose assembly feeds from the air box. Does anyone have thoughts on this ? 2-- I am trying to copy the procedure decribed by others to eliminate the oil in air box problem . I recall reading that some folks recommended using a Gatorade jug to catch the oil as it spews out of the valve cover hose . What are the details of this fix ? Does the jug require venting ? air filters ? Is there a system that will drain the oil back into the valve cover ?
