Hi Im just wanting sum info on oil leaking from the valve cover breathers on my VR Senator 5L. its like the oil isn't draining back down into the motor/sump.
Is this with a standard engine/PCV system or have you modified the valve covers in any way? If it's the standard PCV system I would recommend that you clean the PCV valve first and see if that solves the issue. The PCV valve is fitted in the short hose that runs from the TB to the passenger side rocker cover.
