I was wondering if car idles and runs good but after idling for a minute it starts to smoke is it the oil injector leaking in intake and mixing with the fuel the dealer ship told me they needed to do a detune on it help please , 87 1.3l single turbo

 

What color is the smoke?

 

i actually have a similar issue but kind of reversed, the car smokes and runs a little rough until warm then everything smooths out and no smoke. i'm guessing its side seals on mine.
