1995 jeep cherokee 2.5 liter 160k. About 80 % of the time when I drive a white oil smelling smoke comes through my heater vents. It only comes out when accelerating quickly, its a small amount but its enough to notice. Obviously there is something wrong. Do you have any ideas what it might be? And any idea on how to fix it?

Probably a crack in the heater core. It's likely what you are seeing/smelling is coolant.

Do a leak down test on the cooling system. If it leaks down, you need to physically inspect the heater core.
