Delvac Smell???

[TMax]

Anyone else notice that certain oils have certain smells to them... in the crankcase? Lately, I have been running Delvac and my truck stinks while running. I have no visible leaks and I checked to make sure the oil fill cover was in place. It is a sweet smell but obnoxious at the same time. I did not notice this smell before and that is why I am possibly attributing it to the Delvac. Is there a breather of some sort that could be venting the crankcase?

My rotella get a kinda funky smell but its normaly about the time it due for a oil change. after the oil is changed there is no smell

I have found Rotella Synthetic and Valvoline Premium Blue do not stink.

Thanks for the input. I do not smell it inside the cab... only when I am standing next to the truck -especially where the air from the radiator is expelled from the engine bay.

yup thats when i notice it. the vent tube is about halfway back on the drivers side of the motor and if i have a window down or standing next to the truck I smell it.
