Hi all, found oil in my intake. Not a lot but enough to make me wonder what isn't right.

Can someone enlighten me?

Thanks in advance

If your car has a PCV valve then get it replaced. Should be only a few bucks for a new valve.

I seen conflicting info on the PCV as to its location. Engine bay is pretty tight. This is a 2003 any guidance?
 
Your vehicle has a Ecotec engine, there is no PCV. What do you mean by "intake", the intake manifold, the throttle body, the air filter, etc?

On my old 96 it was in the back left hand corner of the valve cover (looking from the front of the car). 2003 might be in a similar spot.

I scanned a pic from my repair manual. But the manual is for a 96-00 but it's just for reference.

And here's one from the web....

Also, the valve is completely metal on the outside. So do it on a cold engine or wear gloves if the engine is not cold. Found out the hard way when I replaced my old one.

You sure? I found an old thread on here that said the PCV is located on the far left of the intake manifold. And O'reilly auto parts has it listed as in stock for a 2003.

The air intake. If I follow the air filter back towards the engine to a large plastic box with a hose running into it from the engine. The Oil i'm finding is in the plastic box. I'm assuming by way of the hose.

That hose your referring to is the air inlet, part of the pcv. By your description it sounds like the ecotec engine.
