Found out where the vent pipe exits the house

Finally found where my second vent pipe exits the house. The first vent pipe that services the upstairs bathroom and kitchen seem to work fine. The 4" vent pipe runs from the basement (in the area of the sewer discharge line) up about 6' then makes a 90 turn and exits the house (about 2' above the level of the lawn). The vent pipe is just an opening on the side of the house facing east. Dosen't this vent pipe need to extend out of the house somewhat and upwards? Could this be why we may be getting some blockage and a foul odor in the basement. I also want a plumber to do a smoke test on the pipe to see if there is a hole in it and clean it out seeing that there is nothing to prevent debris or an animal from getting into it. We moved into this house a few months ago so just learning about all the surprises. Any help would be appreciated.

That pipe that is 2' above grade is called a fresh air inlet pipe and is there for your house trap to work properly and it should have a fresh air inlet plate over it...can't find an image but the local big box or plumbung supply will have one

Yeah the vent needs to extend out of the house and above the eave of your house or you can talk to a plumber about getting rid of the house trap and this fresh air vent if you have one of these creatures.
