New trucker, new truck..big oil leak

It's definitely coming from the bottom somewhere and not the dipstick. The motor itself is very clean and bright yellow.

 

I have not looked yet, been busy with other job. I got it home and called for assistance. He's coming today at 11am. I went out last night when I got home to see if it had leaked the rest of the oil out just sitting there and it hadn't, so it's only leaking when it's running. There are oil spots everywhere under it because it was dripping down from the entire bottom. What I did notice is that the leak has to be coming from the left side somewhere because the right side tires don't have oil on them where the left side tires are covered (pic above).

 

With it leaking at the rate it is, if I wash it and by time I get to where I can investigate, it'll be oil covered again. That's unless I check it right after the wash.

 

You may be onto something here...They showed me at the dealer that they put a new turbo on it. While showing me that there were two clamps that someone forgot to tighten and it was done when I was standing there.

 

I think this tube here is my problem. It runs up to the side of the motor.

 

I put 5 gallons in it just now, let it run for 15 mins....no dripping. This tube has a little smoke coming out of it, no visible oil, but it makes sense...it's on the left side and only my left side wheels are covered.
