Rear end

[gdh11]

After towing a very heavy 28 foot enclosed trailer about 500 miles I noticed a lot of blow by coming from the rear end vent tube. I have a mag-hytec pan installed. Would overheating or overfilling cause this?

Probably overfilled, have you checked the level in the pan? What fluid are you using?

blowby as in fumes, or liquid coming out. liquid, could also be oil foaming up, from wrong fluid(too thick) or too high a level
