Does it make sense to anyone that car manufacturers still recycle the oil laden crankcase fumes directly back into the intake via the PCV valve. You would think that a little technology could be applied to better separate out the vaporized oil and not bring it back into the intakes where it can mix with the exhaust gases and crud everything up.
A week after cleaning my UIM/LIM I pulled it off again and the amount of oil coating surfaces was amazing in spite of a good working PCV valve.
