Question about 2003 Chevrolet Cavalier

Open Question

The breather hose on my 2003 cavalier has broken away from the compartment that leads back to the air filter but is still attached to the valve cover. Can I just replace the hose without replacing the intake compartment or how is this done?

SOURCE: remove front dash cover, 2003 cavalier & rep ac control cable

Unfortunately, you can do it, but you will have to remove your entire dash in the process.  It's not really difficult, just time consuming.  You can remove the front dash cover by opening the doors and removing the covers on each side.  They are just clips that hold them on.  Take a flat screwdriver and carefully pry them off. You will then see screws on the side that you will need to unbolt, and I believe there are 2 more screws pointed upwards that you can get to if you open your glovebox.  After those screws are removed, remove the defroster grill in the middle of your dash.  There is just one screw to remove and it unclips.  Now you can pry the entire top part of the dashboard off.  There are more clips holding it on, so just be careful when you do it. After that, you will see a bunch of screws on the top side that you can unbolt and then you will be able to remove the front cover that sits behind your steering wheel. With these pieces out of the way, you can finally unbolt the front cover where your stereo is and get at whatever your trying to get at to fix your defroster/control knob.  
I had to go through all this when I installed my aftermarket stereo.
Good Luck!

Oil keeps getting into the breather changed pc valve hoses and filters

check sump oil level--excessive oil level will cause this
have a compression test done on the engine (both wet and dry) to determine engine condition---excessive blow by from worn rings , bore or cracked piston will cause this --- clean/ replace air filter as if there is a low pressure area after the filter , it helps suck oil vapor from the sump

I have a 2003 Toyota Camry with the 4 cyl eng., I was changing the air filter and a hose that was attached to the rear right of the filter housing snapped off. I have been trying to get the part...

Is it a large hose going into the valve cover? If so, it could be a breather vent hose or part of the p.c.v. or e.g.r. system. These systems are sometimes tied into the air cleaner assembly.

I was wandering if you might now why my air filter keeps gettin oil soaked

One of the first concerns is the health of the engine. Do we have a tired old engine allowing the blow-by gases to pressurize the crankcase? If so, the pressure would force the oil up the PCV breather hose and contaminate the PCV breather filter and air filter.

The Positive Crankcase Ventilation (PCV) System is one of the oldest and most neglected emission control systems. The valve is a calibrated vacuum leak controlled by a plunger and spring. Contaminates or changes in spring tension can directly affect the flow of the valve, which could result in oil accumulating in the air cleaner or an imbalance in the fuel mixture. Remember: For each gallon of fuel consumed by an internal combustion engine, one gallon of water vapor is created through condensation. Much of this condensation is formed in the crankcase. The PCV system is designed to control this condensation and remove gases which accumulate from the combustion process and collect in the crankcase, in addition to protecting the environment.

Conditions other than a defective or restricted PCV valve can lead to an accumulation of oil in
the air cleaner, sludge deposits, poor performance, or excessive oil consumption.
Check the following:
• The PCV and fresh air hoses are clear and free of obstruction
• The proper valve is selected for the application
• The valve is functioning properly
• The valve fits tightly in its rubber grommet
• Any O-rings or hoses are tightly secured to their mounting

What is the name of the part that is attached by a hose to air filter

If it's the small hose connected between the breather element inside the air cleaner pan and the PCV valve, it's called the breather hose.

the pcv valve is behind the alternator between the alternator and oil filter. when you remove the oil filter you can see the pcv in the intake manifold. best way to get to it is through the pass side fender under the rubber mud flap thats between the wheel and engine.

Positive crankcase ventilation system

If built like most, the valve cover will have a fitting with a fairly large hose leading away from it.
The PCV valve (Positive Crankcase Ventilation) is found in this line.

This allows fumes forming within the engine oilways sometimes pushed out by minor blowby of the cylinders to be routed back to the air intake so they combust in the engine instead of being vented into the air, something we didn't worry about 50 years ago.
