Can I get a feeler on how many people are having this issue? I don't think it's an issue that should be solved with a catch can. My car doesn't do it, and i'm sure others don't either, so I think oil in the inlet tube is an issue that you should bring up with your service department.

Some people like peace of mind i guess. I hate having to go to the dealership for any reason besides buying a new car. To me a 50 dollar peace of mind about oil in the inlet could be worth it in the long term. Maybe not who knows...all my other turbo car buddies have put one in theirs, but they are pushing 500 horsepower supras and a 93 skyline

I first noticed my old 3.1l grand am started spitting a little oil out the pcv line after around 200,000km. Not the mileage anyone here should be seeing for quite awhile.
I wonder if the OP has a minor gasket leak into his crankcase somewhere, forcing more air through the pcv lines than it would normally see.

Now with a **** load of miles, I would understand, but not a brand new car that doesn't need it. I refuse to believe that these cars have a design flaw where a catch can should have been added. I think that oil is showing up, there is a problem that needs to be remedied. The catch can is like putting a band-aid on a bullet wound.

Well I took off the catch can and the cel went off, and the car drives way better so it was for sure a leak

Its over 39000!
I've caught maybe 3 cups of fluid with my catch-can.
3-cups less through my turbo is a peace of mind I like.
Having said that, if there are any leaks, you will throw a code like Sonic Hotness. Or at least it will drive funny.
I really dislike the factory plastic recirculating hose. I need to figure out how to disconnect it completely from the motor so I can replace it all with quality silicone hose. That will be the start...

You run better oil than he does. Better oil is less likely to have impurities and or break down. I run full synthetic and my oil barely changes colors. The original dexos that was in my car looked like it had 5k or more on it at 1500 miles. Good oil in a turbo car can make more than double the difference it would in a non turbo car.

I didn't run full synthetic until my 14000(ish) mile oil change; I had free changes from the dealer. I've never had oil in any inlet of mine.

Some dealers use different dexos oils. Technically all dexos is, is a semi synthetic oil. I have seen dealers use other oils also. Just because you brought yours to the dealer doesn't mean its the exact oil your car came with. Also not all manufacturers are up to par with oils. Some oils are more likely to foam and or become aerated. This causes blow by due to the gases getting caught inside the oil. The oil rings on your pistons are very thin and easily passed by in this aerated state. Also the oil then can reach a slight vapor state allowing it to pass through to the intake. I don't know if you have ever changed your oil when you car is very warm but pulling the oil cap often times you will see some smoke. This smoke is the vapor I am talking about and passes to the intake through the pcv system. Needless to say the most common cause in blow by on "new" cars is cause by motor oil that is in some way insufficient for the vehicle. Of course there is always the manufacturing the vehicle but I have found it to be less likely.

if there is oil in the turbo inlet, should this be a warranty issue? What can the dealer actually do to fix the problem? I was going to add a catch can, but it has been mentioned elsewhere that it should be a warranty issue. On my ls1 and lm7 engines i eliminated the whole system and vented with the filter instead, but those cars are not daily and require no inspection due to registration type.
This is the inlet on my sonic, i found traces of oil on the throttle body as well. This is with about 1000 miles on the engine.
