If your valve cover gasket is leaking, it can drip on the exhaust manifold and the oil will evaporate emitting a burning oil smell.

I had that smell constantly until I had the oil filter housing gasket changed (not cheap either). Much better now.

You have an oil leak. I had all of them (lucky me, yeah), they all smell similar.

Oil filter housing gasket leaking is the most common
Second most common is valve cover gasket
third is Mechatronic Sleave on the gearbox (it can empty silently the gearbox, careful with that one).
then main engine oil pan gasket (a PITA to fix)
last but not least, main crankshaft bearing

Look at where the oil and dirt crust is located.If you have traces "upper", the the source is a component that's upper. Oil at the bottom ca be any of the above.

If unsure, you have to clean the oil drips, drive for a day or two, take a second look with a flash light to see where the oil is coming from.

Check that the oil filter cap is tight. Silly and simple to check, cost 0

You have removed the plastic under-carriage ? It catches all oil that's leaking, and it splashes the exhaust when turning. If you see nothing at the top, maybe you have a low oil leak (oil pan, transmission, main bearing).

I would guess it's your valve cover gasket leaking down on to the exhaust manifold.

Wipe clean the exposed portion of the flange where the cylinder head meets the valve cover on the passenger side of the engine and check back in a few days for any oil creeping there. The exhaust manifold is directly below.

Hey guys, my valve cover is leaking oil and I'll fix that once it gets warmer here. But driving the car to work this morning I smelled the burning oil smell for the first time, really strong. When I parked there was some smoke coming from the engine. Any chance that this can catch fire? It's too cold to do anything right now so can I take the car to the car wash and use the engine cleaner for the time being? Just to get some of the oil off the manifold?

One of my previous cars (Pontiac Grand Prix) caught on fire while I was pumping gas at the gas station. Oil was dripping on the exhaust manifold from a leaky valve cover gasket. Luckily I saw the smoke, popped the hood and had a full bottle of water in the car that I used to extinguish the fire, otherwise if I didn't notice it quickly, the whole car would have burned.

You're a lucky man .. Opening the hood can (and oftentimes does) accelerate burn due to providing the fire with more oxygen. Also, sprinkling water on an oil fire is generally a big nono.

Well, it was either the water bottle or the next best choice would have been to pull my wiener out and hose the fire down...

I'd rather use the fire fighting equipment gas stations are supposed to have, lol.
