12.7 s60, can you add a crankcase vent?

I have a 2012 Columbia glider 12.7, s60, block vin says 2004, but no EGR no nothing. It just had a tube to the ground for crankcase vent. I just had it dyno'd and it has 1in of blow by. So not anywhere enough to rebuild it.
When i idle the fumes collect under the hood and make it into the cab, I've tried to seal it up but it gets into the hvac somehow and fills the cab quickly.
Can I add one of these, and have the fumes go back to the intake?
Thanks.

 

I tried routing it out from under the truck but the moisture froze over night and it blew a gallon of oil out the dipstick tube.
Needs to be close to the block for heat.
I'll ask the guys at Detroit about putting it to the exhaust, but I'm figuring it will need a filter of some sort. It was -39 here last night and I woke up with a headache, stinging eyes and closed sinuses, I need to do something soon.
Thanks.

 

It helps for a while, I actually turn it to recirculate when ever I'm coming to a stop, it gets into the hvac immediately. After a bit it will just get in, it hangs under the truck, the skirts keep it in. I've idles the last 2 nights and with the truck shut off for 15 minutes you can still smell it when you walk up to the truck, it's like everything under the truck is coated in it from the idling it's done the last 2 days.

 

The floor has 3 layers of sound deadner, foam everywhere else. I cant find any access, maybe door seals?
I think its hvac. Maybe the recirc isnt closing all the way, regardless, I'd like to get rid of the stink all together if I could.

 

It's the blowby. I tried extending it and it froze up and puked a gallon of oil out one REAL cold night. Mt port is front right side. It was a pipe back to the top of the trans and stopped there under the cab when I got. I tried to extend that. Then I took a tube and put it right out behind the front wheel, same thing.

 

I just stopped for a bite and have it idling and throw the fan switch on, recirc on, and it's pretty good, tou do get a little whiff now and again. Turn either off and its game on.
