Hmm I know my cylinder 1 tube seal has something going on not sure about the AVLS sensor. I have cleaned everything up already and the only leak that I can visibly see is the crush washer. Plus im still full on oil which is a record for this car.

As of now im calling it quits. I can drive city allllll day long and not smell a thing but as soon as I get on the highway boom theres the smell. I will have to put this on a lift and have my mechanic thoroughly look over it with me.

My '09 with 31,000 miles has been doing this sporadically since about 15,000 miles. I have a huge subaru warranty so I'm not worried.

One time a lot of coolant was gone from the overflow though, it got down to a certain level, and I watched it for a long time, and at my 30,000 mile service, they topped it off and it has been fine since. I'm not sure if I have some sort of problem or not.

It runs like new, but once in awhile when going 80mph on highway or driving it hard up a hill @ 4k rpm for a few min., or something like that, I'll get that weird hot smell, but sometimes not.

I do not burn any oil, ever. I thought it was just crap burning out of my cats or something, like if you drive easy for a while, stuff builds up, then if you drive it hard, the cats get hotter and stuff burns off- that kind of thing. That doesn't explain an oil burning smell through the vents once in a while though.

I found a pretty substantial amount of oil on the outside of my oil filter yesterday when I was changing the oil. It wasn't loose, so I don't know where it was leaking from. I'll keep an eye on the new one. It would be a shame if there was that big of a leak at only 45k miles

the filter is just inside of the seam between the shortblock and the head. My oil filter was wet for 2 changes and I thought it was loose, but it turned out that the right side headgasket was leaking the oil and it was running along the seam and down the oil filter.

Get under the car, wipe it all clean and shiny, and then check again in a couple days to see where it's wet. I JUST hit 100k KM when it happened. So that's not even 60k miles.

a slipping belt would make a burning smell, if you have a clucth it could not be fully disengaed and might need an adjustment

I know the smell of slipping belts and its deff not that. Its just kinda frustrating that everyone is saying yeah that happens to me too but no one has a solution. I cant be the only one experiencing it thats trying to find a solution. However I do still appreciate the input from everyone! Glad to know im not alone on this

At this point im ignoring it until something gets bad enough to make it easier to find

Don't these have automatic clutch adjustment?

There are other ways a clutch can fail to fully disengage, but it would likely result in other symptoms before getting to the point of smelling.

Yeah, and there's no way this smell is from the clutch, at least in my case.

Double check both AVLS sensors. I had a very similar problem where it would smell a bit like burning oil occasionally when on highway. If I pushed it hard and then came to a complete stop, I would occasionally see a puff of smoke from under the hood. It ended up being my drivers side AVLS sensor leaking. It would only happen when the oil pressure got high enough to activate AVLS (i.e. highway driving, or other situation resulting in high rpm), then it would leak a tiny bit of oil onto the header. It dove me nuts for a while until I figured it out.

Good Luck.

the avls system requires very little pressure to couple intake rockers. oil pressure at hot idle is sufficient. highway cruising at a constant speed is one of the few times the avls is in the low lift mode. just fyi.
