engine ticking on front driver side and has a burnt smell

What is your question?

upon driving in town I noticed a ticking sounding like plastic in bicycle spokes on front driver side along with a burnt smell? I stopped checked oil level it was low so I added more just below max line on dip stick. I then drove home then car drove with a shake but no more smell or ticking. just runs shaky and sluggish. I made it home aprox 4 miles and parked. I waited 30 minutes and restarted but have not drove anywhere yet. I'm to scared

What makes this problem better or worse?

excellerating and just driving at this point

How long has your 2007 Chevrolet Equinox had this problem?
