Hello, An oil separator is allready installed on the driver side of my Cobra SVT 2004. The passenger side does not have one installed, the PCV valve is connected by a hose of a few inches straight to the big air-intake. Do i need to intall a second oil separator on that side, could it be interesting to do it ? Is there a reason to install only one ? (I read on onternet "most of the oil that come's off the crankcase ventilation system comes from the driverside".......true????)


  • You do not necessarily need two oil separators. The one you have on the driver side is sufficient enough.

Do I need a oil separator for both passenger and driver side on a stock Mach 1 4v engine


  • To prevent the most oil & contaminants from entering the intake track, we would recommend a JLT V3.0 Satin Oil Separator for both passenger and driver side. Most of the blow-by comes from the driver-side, so installing just the driver-side separator would catch most of the contaminants, but including the passenger-side would yield the best results.
