The old truck looks like its overheating at idle when she's hot,.wispy smoke coming out from under the hood,.

i,ve been running it with no breather on the oil pipe for a couple of years now,. it's really cut down on all the oil leaks,.but she's huffing pretty good out the oil fill pipe now when it's hot,.

Interesting thing tho,. it's only when its hot,.stone cold there's little to no blowby,.

I had a series 60 that didn't like rotella T ,. it huffed way more blowby than if you used mobil,.

I,m wondering if it's the cheap 15w40 i,m buying at canadian tire,.?

Different oils will burn off differently. I know when I used Rotella, I always had a strong oil smell after I shut it off. That went away when I changed to M1.

IMHO, put a CDR back on it.

How many miles on the engine?

And yes you will have more blow-by when hot than when cold.
