Crankcase Vent Valve Kits for M52/54
Over time, the crankcase ventilation system in your M52/54 equipped BMW is susceptible to condensation. This traps moisture inside the separator, eventually clogging it. This leads to increased oil consumption and smoking. The fix is to replace the oil separator as well as the hoses going to it. Our kit includes everything you need to replace the oil separator in one package. Additionally, you may want to consider upgrading to the cold climate version of the oil separator. This version includes extra insulation around the separator to help prevent condensation inside the separator.
 All kits contain the following parts, in addition to those specifically listed in the description:
  • New Oil Separator
  • New ventilation lines
  • New silicone hose

Engine Oil Separator (Air Oil Separator)

Oil Lines

Oil lines are used to transport oil around to the various systems in the vehicle. They operate under heat and pressure. They should be inspected for cracking, drying and aging at every oil change. It's a good idea to replace the clamps when you replace the oil lines.
