Only trucking two years but .getting sick from truck and no one else smells it

I have 2007 9900i international eagle
The engine has extrem blow by
Crankcase vent blowing out a foot long steam of steam and smells to me really strong but to no ones else
Also engine is pushing oil out ofvalve cover and any seal through out the motor
I told my boss its makeing me sick
Its all i can taste
Bad headaches
Chest thraot lungs sore
Today i was seviceing it and guess since i spent 7 days in truck breathing this
I can t even go near the vent the tasteintensifies i feel it in my skin
But everyone says they do not smell it
Only one guy said he kinda smelt it
This ever happened to anyone
I feel like i am going crazy
No one else smells it
During summer i flat deck only spend a night or two a week
But winter we log and now spend 6 days a week and now its effecting me bad

 

I am in canada sudbury ontario
Into logging

 

Durring sumer are company dose gaurdrail alone hiways and roads all i flat deck all the supplies

All winter we go logging
Every Saturday exept today cause of faily day
We serviced it today
But i have to grease
G
Check oil
Tourque tires
Lights
Check rad
Just go through it all

 

Your right
I told him yesterday but all he cared about was another load
We even have a back up truck sitting there doing nothing
I told him let someone else run mine
He blew up
Thats what i am telling my wife
Its really makeing me sick
My lungs and throat feel burnt
I dont want to drive it
But got a familly
Think i am gona do like everyones saying
Vent it out the back
And its not that he is cheap
He usally fixes anything i ask
Its just he dont belive its happing
And wont let a truck stop during season
Telling me to drive with open windows heat on
But its the heater thats sucking it up
Going to fire department and going to see if monday i bring it there if they have and or will test the air qaulity un it
And put hose

 

My camper has the exact one that all the sites showed name brand model
Exact same
Going to camp to grab it
Thanks
Feel much better now that i now its the truck
Like i told him if you could walk up and notice ut it wouldnt be an issue
But you gotta be in it and run it to see
