I can hear popping on the left side exhaust. I don't think it's happening on the right side. Does anyone know what is causing it or what I should check?

Most likely and exhaust leak or rather an air leak. You have a hole and or loose connections somewhere where it is pulling in cold air and mixing with the hot exhaust which will make it pop. Is it a constant pop or pops when you lift off the throttle?

It pops when I lift off the throttle.

Air leak then, you have a cracked or holed pipe on that side.

Actually, I took it for a ride today and it also pops when I give it gas. It doesn't pop when idle, that I have noticed. I will take a look at the pipe.

I just noticed today, the same side that has the popping is also releasing blue smoke. The other side has no smoke.

Okay, sounds like you have other problems now, either a ring or rings going bad and/or some valve seals. Do a compression check for rings, maybe even a leak down check as well.
