i'll be running a non vented setup, i dont see any real advantages in going vented. my high quality baffled separators should remove most of the oil from re-entering the intake path making vents a dirty solution.

I wont be deleting my pcv. there are lots of ways to lose weight, starvation is not one of them.

As for drilling. if i can unbolt the baffle to clean out the metal shavings then i have no problem with it. one of the many night terrors i have are from sand/dirt getting in my motor and eating all my bearings.... So i really have no interest in drilling it unless i can 100% say i got every morsel of dirt out of it.

 

I punched holes in my vc baffle to avoid shavings. Did it near the pcv and intake hose ports. There is no way to remove the baffle to clean it out.
This did not solve my issue (AP1) and my oil consumption went up!!
I went back to a stock vc....
Does anyone have photos or more documentation of putting holes in and it's effectiveness?

 

The advantage is pretty obvious, no oil in your intake tract and there isn't vacuum on the crankcase which leads to more oil in a catch can. I'm not sure applying vacuum to the crankcase has any benefits over vented, except for appeasing your local emissions laws.

 

the benefits, from what i understand..... which i could be totally wrong, are; 1 longer oil life, 2 reduced moisture in the oil, 3 reduced blowby, 4 reduced engine wear, 5 environment.

disadvantages. problem i currently have.


ty for the effects on punching. it was going to be the method i'd explore, but since it hasn't remedied your problem, i'll be going with my own solution, which is to reduce the size of baffle inlets on the inside of the valve cover.

I know that this will reduce the amount of oil in to the pcv system/intake track as i'll be directly reducing the area it takes in air/oil from. perhaps i'll also add a turn down on the ends to send sloshing oil back down... How much oil could possibly be sloshing around up there?

 

1-4 are questionable or very minimal imo. Longer oil life? I'm not sure how it lengthens oil life. Moisture gets reduced in the oil as soon as it hits 200F+ as water turns to gas, and gets pushed out of the crankcase via pressure, so it leaves one way or another, regardless of vacuum on the crankcase. #3 and #4 is very close to nil as well in my experience. To each their own, but the primary reason the crankcase goes back into the intake is #5.

 

if you punched holes in the baffle without removing it, then it won't work because there's a lip around the holes you created that curve upwards and blocks the oil from flowing down the holes

 

Agreed

1) this has no affect on oil life
2) moisture in oil will evaporate when the engine is hot, and forced out the valve cover vents. As long as you're not using the car only for 5 minute trips to the grocery store, you'll be OK.
3) Under load, the PCV is closed anyway, which is doing nothing to help with blow by. The only time the pcv is opened is during high vacuum (part throttle, off throttle deceleration, and idle).
4) This is questionable. As long as the crank case pressure is being relieved, seals will not be damaged.
5) Environment is the primary reason for the pcv. Even then, the impact is minimal if you're using a baffled catch can, along with a filter where it vents to atmosphere.

Ideally you do not want the crank case vapors to be recycled back into the combustion chambers. There are no positives for this (emissions excluded), and only negatives. The contaminated crank case air will reduce the octane of the fuel, and actually hurt performance.

 

Correct for the intake breather, but I punched from the top side hole at the pcv. This makes me think most of the oil intake is at the breather hose...

 

In addition I notice most of my blowby smoke during part or closed throttle when coming to a stop on a downward grade

 

how is capping the pcv preventing the dispersion of crank case pressure when you have a giant port on the front of the valve cover?
