When accelerating hard and revving engine around 2000-4000 rpm I smell burnt oil smell from my A/C. The smell is similar when I open the oil filler cap or dipstick.

Did hunt for oil leaks and solved them:

  1. At cmp sensor, this one had no O-ring. Replaced.
  2. On valve cover. Wiped clean and tightened bolts slightly. Still dry
  3. Near oil filler cap. Probably didn't tighten well. Wiped and tightened.

But it still has burnt oil smell..

Have you noticed any oil leaks under the car?

It could be that your oil level sensor seal is leaking and you will not see it because it is accessed under the car, probably higher up, past the oil pan and you smell the burning oil but can't find it because it burns off too quickly. You'll have to wait till the car cools down in order to check the area for oil leakage as well as part replacement. You should locate the Oil Level Sensor in your vehicle and check this first for leakage. And since it's a 2002; I would do an engine flush to loosen any gummed up crap inside the motor and then add new fresh (manufacture specified) oil.

Could you smell it when you open engine hood? Normally when you change oil, some gets spilled on exhaust pipe in engine bay. They get hot when rpm goes up, hence the smell. I suggest using some degreaser to clean exhuase pipe and any parts that gets hot.
