I have researched this topic extensively and have tried multiple fixes. I have used an oil separator, full length intake baffle, larger lines, etc. None of them were 100% successful until now.
I was reading another post from 2006 and the original poster claimed success with this same setup, so I tried it,and it flat out works. I would give him/her credit but I can not find the post now.
It involves using 2 pcv valves ( I used the Lightning pcv) elevated away from the intake. The pcv in the intake is replaced with a 3/4" male to male fitting, then a section of 3/4" heater hose mine is 3", into a 3/4" T, a hose on each side of the T joins 3/4" 90's, then another hose that house the pcv valves on each side. Then the pcv's 90 fitting are connected to each other via a 3/8 T fitting.
Finally, the other leg of the 3/8 T is connected to the line that goes into either your intake vacuum or your oil separator. I kept my separator to monitor if any oil makes it that far, so far none has.
After multiple full throttle blasts I have yet to see any oil in my separator or out the exhaust. Before this mod, my car would smoke after a long idle time and a WOT blast. I have included a diagram that I made to help explain it and picture of my setup .
I have also checked crankcase pressure/vacuum to be sure there are no difference between a single/dual pcv set up. In both situations with my vacuum/pressure gauge attached to my dipstick tube the reading were identical at 2"HG vacuum.
The theory of using 2 pcv's is to decrease the velocity while maintaining the volume of air. Less velocity will carry less oil.
With this mod my car seems to have a deeper exhaust tone, It also does not smoke at all , and the oil separator is bone dry.
