Burning Oil

I've noticed that when I start the car cold at around 10-20°F outside, I can smell burnt oil for around 30 seconds, though no blue smoke and no excessive white smoke. Crankcase vacuum is normal, and I've noticed a burnt oil smell when shutting the car off after a drive in which I've driven it hard, like top of the Rev range hard. Is this normal?

Oil and burning rubber

Flat engines can accumulate a small amount of oil in the cylinders when they sit around. Start up and there you go

After I drive I smell that lovely Oder de-oil & rubber

Whaaaaat? A 15-yr old Porsche with an oil burning smell?

All kidding aside, it could be perfectly normal (and definitely not unheard of) but I'd get up under the car and do a good inspection just to be sure. You could have a seeping RMS, spark plug tube, or any of several other places are known to weep/seep/drip oil.

Also be sure to check the top of the engine for power steering fluid; sometimes a power steering line will start to leak and it drips on top of the engine (under the intake manifold) and then burns off so it never drips. Usually people smell an oil smell for months until the power steering pump starts to moan when they turn tightly. Then they check the power steering fluid to find it mostly empty due to a leak in a line.
