i'm so glad i read like 5 pages of info on this last night

Ok so basically there are 3 ways to vent the crank case. #1 is the PCV and the stock rout, but under boost it doesn't perform well. #2 is venting it into the intake before the turbo, but that makes the turbo and intercooler get all dirty.

now comes the great part, splicing it into the exhaust would be one of the better ideas so far if it were not for the whole burning off oil thing. But then again how much oil is gonna go into this hose? If it isn't much it shouldn't smoke considerable right?

then you can have a separate evac system. i'm considering going down to the local hardware store and looking at vaccum set ups for minor stuff.

Who knows maybe someday i'll join your fleets of turbo'd cars and know what this "boost" feeling is

lol, i haven't even used the 23 dollar exhaust slash cut kit i bought, i've just had my pcv completely removed and venting to atmosphere and it works fine, just not to enviroment friendly i guess :P

yeah its one thing to vent it into the air, but for power you need a vac to suck out the pressure in there. AND you figure the entire crank case gets to vent from what 2 areas? so if you are only gonna vent it from one area it should Definitly have a vac source.

So now here i am thinking of what would be a cheap effective way to heavily draw gases from the crank case without sucking up oil. my head hurts

just run one of the already mentioned slash cut methods (exhaust or pre turbo intake) and use a baffled catch can in line. oily vapors are going to come out of the crank case regardless, that's why it's best in my opinion to use the exhaust slash cut method. who cares if you get a slight hint of smoke out of the exhaust under boost, it's not like you have to deal with it inside the car, and it's not like it will be so bad you'll have oil dripping in your exhaust or anything.

so its been a while since theres been any activity on this thread... but im about to do my own setup, and i want to do the exhaust method, but what kind of hose can you use so that it wont melt onto the fitting? seems like regular vacuum line wont be able to handle the heat.

weld in a metal slash cut tube. and attach the hose as far away as you can. they also make a high temp hose that would help in this application. either way you need to use a metal slash cut tube. make sure you put a check valve in this line aswell.

Didnt the Dodge Caravan come with something like this stock, I think it has a metal tube running from the block to the exhaust
