It doesn’t smoke like that at cold start.

Injectors are new.

Smoke is white with maybe some blue. Does not smell of gas.

A few more videos that may help:

Driving 15 minutes is absolutelly not enough to get the engine warn at all.Also when was the last time you had service done? Engine is kinda noise.
Were the valve giudes ever done on this engine,? With 156K more likely that is what you need..on 87 i have done several engine valve giudes at even 30k miles( 87 had problem with them)..i`m sure your is overdue.
