Possible causes for engine smoke?

Hi all,
Need your help in diagnosing engine smoke coming from my 2012 X5 35i. Have about 75k miles, oil change not up yet. Trying to look for an open mechanic during covid19 has been tough so hoping I could find some answers here.

So, smoke seems to be coming more from right front side of car during idle. I assume the smoke is dissipating while I drive since I don't see the smoke while in motion. Smells like burning rubber. Weird thing and maybe this will help diagnose further is that when I have the heater on, u can smell and see the smoke coming through vents, but when I have the A/C on, no smell or smoke to be seen. If I have everything off, and windows closed, no smoke. But when I have the windows open and stopped u can definitely see the smoke wisping away from the front right side. There's not a lot of smoke, but definitely enough where when I was waiting for my coffee at Dunkin' Donuts at the drive through, it became bothersome and worrisome. Haven't driven since that moment because I was afraid of causing an engine fire. Any ideas or answers?

Thank u

sounds like a valve cover gasket.

do you want to know so you can ignore it and keep driving? Id just find a shop if you cannot DIY.

Thanks ARD. Sorry for the late reply. It indeed was the valve cover gasket. No, I did not want to know so I could ignore. As soon as I got some leads from valuable members such as urself, I went to get it fixed.
