Could it be a pluged pcv causing oil to get in number1&2cylinders

Conceivably. A clogged PCV valve could cause crankcase pressure to rise and force oil up along the pistons, but one would expect it to occur on all of them, not just those two. Also, some vehicles don't even have a PCV valve. Without knowing specifics on your vehicle, I can't make specific answers.

Oil in pcv valve

It would help to know the year, make and model of vehicle.
many older vehicles (pre 1970) had PVC issues when the crankcase breather tube is plugged. On other vehicles with a "closed" system, the PVC valve can become clogged when too much oil is being drawn due to worn valve guides.

PVC Replacement

Sorry Darryl I am not conversant with PVC connected to cars. Do you perhaps mean PCV?
Positive crankcase ventilation is sometimes controlled by a valve which should be checked, cleaned or replaced as required during routine maintenance.

The PCV valve is often found screwed into the engine valve cover and is part of the engine breather system which vents foul crankcase emissions either into the air cleaner or into the inlet manifold.

I hope this helps.

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.

How to replace a pcv valve

3.8 or 3.1 liter? The 3.8 liter has a cover on the passenger side of the intake plenum. The map sensor is possibly mounted to the top. Twist the cover to remove. The pcv valve will be underneath, make sure you install the o-ring exactly how it was on the old one! The 3.1 liter is on the drivers side of the front valve cover. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

What hoes goes to the crankcase ventilation pcv valve

Hard to say without knowing exactly what vehicle we are talking about..but as a general rule your pcv valve normally has a 3/8 hose that attaches directly to your plenum or intake. It has to be an open vacuum port NOT a controlled vacuum port...if this doesn't help send me the vehicle type,year and engine size and I can pull up the vacuum diagram and send it to you.

Is the pcv valve replaceable in the 2001 Sunfire 2.2L engine or is it built in to the valve cover

Yes the PCV can be replaced. It seals into a rubber grommet in the valve cover. See pitcure of valve below.

We have 1998 chevy cavalier and is burning a lot of oil, per 1000 miles we ad 1 litar of oil., we did check for pcv valve but looks like this vehicle does not have pvc valve that we caqn check , can you...

If Pcv valve is not working correctly car will run real bad starving for air. And check engine lite will come on. I would add one liter of Locus oil stabalizer and drive it, Sounds like it's about time for a overhaul. best of luck to you.
