is it smoke or fumes, oil does fume at operating temp. no issue with that. Just make sure you're using correct oil viscosity.

which car is it? If you have a PCV valve, it might be stuck closed. you can try replacing it. Its wont take more than 10min.

Search YouTube for pcv replacement procedure. Best to take it to a mechanic

PCV for your 2nz and similar toyota engines is located on the valve cover. Its a small L shaped plastic valve with a small pipe attached to it. Take the plastic cover off and you will see it.

A very basic test is to remove the pcv valve and see if it rattles, if it doesn't, it's most probably choked. You will have to replace it then.

Looks like your pcv valve is malfunctioning and not working properly. Not evacuating blow by gases.

Take a clean picture of the valve cover. It's most likely on top of it
