Head gasket leak. Have you had other engine problems?

What @PNWTahoe said. Needs a compression test with all plugs removed and inspect the plugs and post pics here of the plugs. Likely, if it is head gaskets, the coolant is in the oil and the oil will look milky and will also show on the dipstick and under the oil fill cap. Is oil fuller than normal and coolant low?

I was thing head gasket. Just got the truck 2 days ago. Was taking to shop cause they said Tran might slip. Drive 15 min then I saw all the smoke every where.

If they have the right equipment they can also sniff at the radiator opening for exhaust gasses.
