I do not have a down tube or a PCV on this engine. It did have a PCV valve at one time. I may have to fix that. The condensation on the inside of the valve cover does taste like coolant and leaves a very light green tint on the inside of the valve cover. I will re-torque the head and try the dye. I do have a slight leak in the radiator but I didn't think the two issues could be related. Which is better way to go, the down tube or the PCV valve?
