Where is the PCV valve location on the car listed above it is an EX model.
I can smell a burning smell through vents and when I exit the vehicle and also it burns oil or uses it because I have to keep putting it in every now and then.

Hi,

I attached a pic below showing the location of the PCV (pic 1). However, if you smell oil burning, it is likely something other. If the PCV is plugged, it will cause excessive crankcase pressure within the engine, so you should certainly inspect the valve's condition and confirm the PCV hose isn't plugged.

Have you checked for oil leaks, specifically from around the valve cover? Pic 2 below shows the cover. If you are leaking oil from the cover gasket, you will smell it, and it will lose oil. Oil will leak down onto the exhaust manifold and burn off, and if bad enough and hot enough, it could cause a fire. So, check that as well. If there is a leak, it will likely be at the base of the cover, and you will see it.

Let me know if this helps or if you have other questions.

Take care,

Joe

I'm looking at the picture you sent for the PCV valve and I'm wondering where the actual location is because the pic isn't very descriptive.
