Just curious as to what others do to fill oil in an engine with no filler cap? There is not one on the Tall Valve Covers that are currently on my engine. There is not a filler tube on the intake either.
I doAlrighty then ; I think you DO Need a V C breather (on one side valve cover) AND a PCV valve (on the other
side valve cover) - - too let your engine breathe ; and then help remove any water vapor & condensation, inside
u'r engine. (plus , gives you that place to add oil) .
just my 2cents . . but , I also use a DF-17 PCV valve.
