New PCV experiment......
#61
You think it'll pull less oil out using the drivers side valve cover?
EDIT:::: I read you post above.....I'm gonna try that this week. Use a clear hose to see if oil is getting sucked through it.

Good luck....make SURE you have a PCV valve in the drivers side valve cover to control the amount pulled....or if you have the RevX can that it is plumbed inline.
Do you think its better to pull vacuum from the drivers side valve cover...rather than pulling from the pass valve cover or valley cover port?

And here is a short explanation:
The oil mist/vapor that results in the oil coating the intake is only one of the many combustion byproducts and harmful compounds that are evacuated from the crankcase. The oil mist/vapor is a suspension caused by the internal parts flinging it so it needs a chance to slow-down & cool to condense the suspension to droplets that are then trapped in the can. But the harmfull stuf is the acids, water vapors, carbon particles, and unburn't fuel that if not flushed out will cause harm over time by coroding the internal parts and contaminating your oil causing it to protect less & less. What you have sounds like mainly water vapor & some unburnt fuel, etc. It to will condense to droplets and be caught by the can where the other gasses will be drawn through and burnt in the combustion chamber & then the cat.
The cars of today ALL have closed crankcase ventelation systems, and ALL will result in some oil in the intake. Some are worse than others (our LS based especially) so that is the reason we modify the systems to prevent this. To test and see if you need one, simply unbolt your TB from the intake & reach in with a white paper towel (into the intake snout). If it comes out clean, you have no issue. If it comes out oily, you do.
The problems we see the most are where people will delete the PCV system and just run breathers, or worse...open hoses hanging down from the valve covers where they will pull dirt & debris directly into your motor. The breathers relieve excess crankcase pressure & are filtered to keep dirt out, but do nothing to evac or flush the harmfull products out. So each time you run up to operating temp the harmfull crap "flashes" off to vaoprs and unless pulled out with vacuum. remain in the crankcase for the most part and when you shut down & the motor cools, they re-condense into droplets inside your motor and coat the internals & contaminate the oil. This is accumulative so over time damage results.
Any questions anyone has please post them and I will do my best to answer them for you. This is a very misunderstood issue and the only solution is knowledge. Far to much misinformation out there by assumptions and the thinking of 30 years ago.

So capping off the port thats rear facing on the pass valve cover, then running a regular PCV hose with valve from the forward facing port on the pass valve cover to the tb and a breather on the driver side cover? What do you think about the evacuation method into the exhaust? Would you run the driverside port to the exhaust on this setup? Thanks for the write up!

Thats it.....cap everything else off. One way for air in....one way for air out.
Put a one-way check valve in the line from the exhaust and the PCV valve in-line also. Or maybe don't even use a PCV valve. Try it both ways and see if WITHOUT the PCV valve you don't get a smoke trail behind you when you go WOT...if you do, put the PCV valve in, that will fix that problem.
This will allow fresh air to enter the pass side valve cover, then flow from there down into the crankcase and up to the other valve cover and out through the vaccum line.

No.....if you're gonna use the exhaust vaccum setup I think the best way to do that is.....run the line to the exhaust, then pull crankcase air/gases from the drivers side valve cover....then a breather/filter on the passenger side valve cover port.

BTW...I used to be in Anchorage all the time for work. I friggin loved that place. Used to stay at the Hilton downtown. I was there every month for about 6-10 nights for a 2-year period. It was my base for 2 years going back and forth to Asia and the Middle East. I don't know how many times me and my friends would "walk" into the "F-Street" bar and stumble out. Good thing the Hilton was literally a 1 minute walk. Hows that place doing, still have that big cheese block on the bar?
