^^at least that much I am aware of.
But, my air box is leaking oil, and when a put a filter on I can now smell oil in my car coming through my vents.
I think my rings are going bad, but I'm not sure, any suggestions?

What car and what engine?
Ashallee.... This doesnt seem possible at all... are you sure you arnt on hallucinogenic mushrooms?
For one.... your air box cant leak oil and has nothing to do with your vents...
The only way to get oil in your airbox (other then putting it there) is by means of the crankcase ventilation hose (a hose that goes from the valve cover to the intake /air box) but that usually doesn't happen (although it did on my 3.1)
Maybe the EGR.... if your engine is crap and about to go... but in the air box? and even then you would (or should) only get a soot, not liquid oil.
If your rings are bad.... you will see blue smoke coming from your exhaust.
As for the oil smell coming from your vents... the only way I know that could happen would be from vandalism..... so with that said.... are you sure someone didnt mess with your car?
The smell could be coming through the vents, if the oil was ending up on the hot exhaust/engine and smoking. Then the smoke/smell would just get sucked in the vent system, and pumped into the car. This exact scenario was happening with one of our company vehicles. The helicopter pilots had to drive with the windows down, to not get sick/feel sick from the fumes. My boss finally pulled the car off the road, once the heater core went south.
isnt the brake booster right beside the air box on j-bodies? might have sprung a leak...

I have a 2001 2.2 Cav.
It's the intake air box above the valve cover, and no I'm not kidding when I say it is leaking oil. I pulled it off to plug in a vacuum line and found that it was oil, I'm not kidding at all, it IS oil. Even my Butterfly plate has oil on it. and there is oil on the crankcase ventilation hose. It's too cold to pull it back apart but if it gets warm tomorrow I will send you pics.
It's not the oil is in my vents, it just smells like oil in my car, only when I have the air on, heat/ac. My EGR valve needs to be cleaned but nothing is wrong with it, I checked.
As for the mushrooms, I could only wish I was.

Checked that too, it isn't that.

I figured that was the primary cause of the smell.

Theres that nipple on top of your valve cover. Its a breather. its supposed to plug into the air box on top of the valve cover. Youre going to get a little bit of oil into the airbox due to it placement. Is you oil level too high so its shooting that much oil into the air box?
Well i have had a similar issue with my cavalier. Its a 99 2200. I was having alot of blow by issues and having oil coming out of my crankcase vent tube that feed into the air intake i made. I was using probably 2 quarts of oil a month before the motor went south. I was having some blow by issues for about 2 years before things got really bad. To make a long story short here after all this time the motor finally wouldnt start one day. Took it to a friends shop he pulled the head and founf that the number one piston broke it ring landing. Looked at the wear and tear on the cylinder wall and figured that it broke around the same time i was having major blow by issues.
To be honest i think the motor has a bad blow by issue. Either the rings are shot all to heck or you have a broken piston. Id sugest to get it to a shop and do a compression test asap.
OK its a LN2 with a valve cover so I bet I know what it is....
My buick had this problem.... and it got so bad the car wouldn't run right and I ened up having to remove the hose going to the valve cover.. I actaully got enough oil in the throttlebody that it clogged my idle air bypass..
It almost has to be the hose going from your valve cover to the intake or the PCV valve (or both).... There should be a screen or something in there that keeps this from happening but sometimes for whatever reason it still does on older cars (people working on it put it in wrong or whatever)
A really easy fix for this is to just put a small filter on your valve cover where the hose goes in and just plug the hole in the intake where the other end of the hose goes (I used an old IAT)
As for the PCV.... Im not sure where it is on your car but mine was in a hose the hooked to the intake manifold aftter the TB on my 2.0, make sure there isnt oil in it assuming it redirects somewhere before the TB
Okay, that's what I did, I put a filter on the part of the block, but I haven't found anything good to plug up the other end, and that's when I started smelling the oil in my car.
I'll clean out my air box and the butterfly plate Then check it in a few days and see if it's any better or not. I just wanted to know what the problem was before I put the intake on.
Thanks

If worse comes to worse... go get a bolt thats the same size as the hole (but head is big enough that it wont slip through... and shove it in there LOL
good luck.... and carb cleaner works pretty good for cleaning out the tb.
