SOURCE: on a 2004 Impala what is that pipe/hose called

I beleive it's simply called the PCV hose. If you go to the auto parts store, the hose may come pre-formed or they will be able to supply you with the correct diameter hose. I would take the old hose with you for a match up.

I have oil blowing out of the filler tube when I remove the cap on my 2008 Chevy Colorado what could be the problem

It's most likely due to a clogged PCV valve or clogged/kinked PCV hose. I'll include a video showing PCV system operation.
I've seen this symptom many times on various engines, and the PCV valve was usually clogged/defective. A clogged PCV valve results in crankcase pressure build-up and fumes/oil exiting places on the engine that it shouldn't. A severely clogged PCV often makes oil leak/exit out of the dipstick, even with dipstick in place.
The good news is... if the PCV valve is clogged/defective, the "cure" is a very cheap fix. Usually less than $5.
PCV stands for Positive Crankcase Ventilation, btw.

But note that on some engines (those where the oil filler opening is directly above the rocker arms/valvetrain) it is normal to have a small amount of oil "spray" come out, as the rocker arms are dispersing oil thru their oil passage hole on top.

(Whenever posting vehicle questions, always please add the engine size/type. It helps in more accurate diagnosis.)
Also, please rate via the helpful button if you feel my answer helped you out. Also post back and let me know if this cured it.

should be at the top of the motor running into one of the valve cover. if its a 4 cylinder then there is only one valve cover and there will be a half inch hose running to the valve cover. pull this hose of and there will be you're PCV valve.

My 2004 Ford Focus SE is pulling a p2195 code. I have replaced both O2 sensors and fuel filter. I drove it for 15 miles before it started acting up and the check engine light came back on pulling the same...

Check your PCV valve and the hose that attaches to it. This PCV valvle is usually located on top of your valve cover and usually have a 90 bend in it. I would replace the valve and check the hose for any cracks. The PCV valve should look like thisbrickdog2000_0.jpg.

PCV valve for 2004 Hona CRV

PCV Valve Operation: 0900823d80049deb.jpgA vacuum-controlled metering device that regulates the flow of crankcase fumes in the positive crankcase ventilation system by allowing more flow at high speed than at low speed, and acts as a system shutoff in case of engine backfire to prevent an explosion in the crankcase.
Depending on your engine size, the PCV is a different style and slightly different location.

Usually they are mounted in a hole on your valve cover.... connected by a vacuum tube.
Some are mounted with threads into the engine block (usually by the oil filter)

On the '04 Crv - it is nearly inaccessible behind the AC compressor and beneath what looks like an old vacuum advance. Most PCV valves today do not need to be replaced, unless there is actual valve failure, which I have not seen happen. I would not be concerned about replacing it.

Thanks for using FixYa - a FixYa rating is appreciated!!
