Default Burning oil smell

I found a few threads dealing with burning oil smell... but none seem to fit my issue.

The one that comes close talked about an oil return line dripping on the downpipe, but I do not see any oil on my DP.

Here goes:

I have a 2003 WRX (stage4 setup FMIC, pinks, catless turboback, gutted uppipe, etc.)

Recently I started seeing white smoke out of my hood, but very little and very sparsely timed.

I smell a good amount of it when I am stopped and while in my car.

ideas? No oil on the ground or anywhere else I can see in the engine

Since you are saying you can't see it, you may want to check your passenger side valve cover. When they begin to leak, they'll drip down on to the up pipe which is very difficult to see. Most of it will burn off or find spots to lay in if you still have the factory exhaust manifold with heat shields. You should be able to see the valve cover leaking at least from underneath the car.

The other tough spot to see really good is right under the turbo, either from the turbo itself or the return line. The downpipe is behind that stuff but it may drip and blow back on to the downpipe.

Lots of other spots where older engines will begin to leak but all are fairly easy to spot. Even stuff that is hidden like the oil pump and/or cam seals will eventually show drips out the bottom of the timing belt covers.

You gotta get your nose in there and smell around. If you can smell it in the car, you'll be able to smell it at the source as well. Just gotta look better. You'll find it.

could be an exhaust leak, anywhere from the heads to the up pipe and is getting blown into the cowl and windows and that's the white smoke possibly too

before you start ripping into it make sure isnít the AC dump tube. it is conveniently placed so it burns on my aftermarket downpipe. i just cut it off .

Found the source of the oil smell... hoping someone can help me diagnose the actual issue, or next steps.

The smell is coming from the oil dripping on the uppipe (or at least what I believe to be the uppipe)

That's most likely going to be valve cover gaskets
