Many people believe PCV design is one of the major factors that cause excessive oil consumption in a Gen-3 Prius after 150K miles. This excessive oil consumption results in EGR circuit clogged up. One proposal is to add an oil catch can.
In a normal placement, the oil catch can is placed after the PCV valve. However, the PCV valve is buried under the intake manifold and hard to reach for future replacement. I wonder if I can swap the position of the PCV valve with the outlet fitting of the oil catch can?
Basically 1) remove the PCV valve from the crankcase wall, 2) connect the oil catch can directly to the crankcase wall, 3) mount the PCV valve to the outlet fitting of the oil catch can, 4) finally connect the PCV valve to the intake manifold.
Do you see any problem with this arrangement?
