There is nothing in the oil and the head gaskets are newly installed.

I also do not have a heater core.

I'm thinking I mislead you with my mention of the smell being sweet. Its not an antifreeze smell, Its a petroleum type smell but not like straight gasoline or straight exhaust. I was thinking it was blow by since I can see some smoke occasionally coming from the Oil Filler tube after long drives.
