Here is how I installed an oil air separator for my wife's Hyundai trajet.
This separator is needed due to the high concentration of oil mist in the blow by gases. This mist comes from the outlet of the pcv valve and goes into the intake manifold. Oil burnt in the combustion chambers is not a good thing for any engine.
Good thing I did this since the silicone hose got discolored from oil contamination. A fuel grade rubber hose became part of the solution.
Even the old pcv valve has lots of oil mist from it so thus engine has a problem for many years.
Step 2: The Diy Oil Air Separator.
Step 3: Installing the Discharge Hose.
Step 4: Installing the Suction Hose.
Step 5: Completion!
The oxygen sensor for this engine I will replace soon since the oil contamination would have coated it.
I hope this instructable has been helpful to other car enthusiasts!
