I had burning smoke coming from the right front side last night as I was driving. I looked for where it was coming from and there was oil spashed all under the wheel well

Oil leak but not the drain plug. Someone advise maybe where the sensor plugs in not sure

So I have a few different things my gasket seal valve cover I guess is what he called it I'll send a picture and of what he gave me to replace it with but it has instead of bolts coming out on one side some moldable putty almost like some liquid JB weld into the holes but it's leaking oil from there there's no water in my oil cuz my oil still good I don't know how to do any of this stuff anymore I did work on cars with my father when I was younger but I've never done it by myself and I don't have anyone to help me so I'm just trying to learn how to do it

Cruise control quit working ,uses/or loses oil between oil changes.
