They're easy to clean w/ brake cleaner. But then I've never had one that looked "dirty".

The PCV is "positive crankcase ventilation" if it becomes blocked it can cause oil to be pushed into the cylinders and be burned leading to oil consumption....

its one of the items on the check list of GM to address when looking into the newer versions of the 5.3l consuming oil...

Thanks everyone! you are all very helpfull and the video was nice! I looked on the web for the part and its only around $5 so i might as well replace it. Any other things on the list i should check?

So digging around checking things on the car and when i went to take off the oil cap to top it off i noticed there was a little bit of cream colored residue in the cap but when i pulled out the dipstick it just has clean oil on it? Also the fill tube moves around slightly and looks like oil may be seeping out, sorry about the terminology im not very mechanical lol but i attached a pic here hope this can explain it<O</O

The cream colored goo is oil and water, its probably just moisture build up at the cap...if you are not seeing any coolant usage or other signs of water leaking into the engine, I would not worry too much about it, wipe it out and monitor.,,

You might try removing the oil filler neck and cleaning or replacing the o-ring.
if the plastic is cracked, replace the oil filler neck...

Thanks! Ill give it a shot tonight, i hope this slows down the oil consumption some. It looks like it is just on the cap, i havent had a coolent light go on yet but it is also cold here in IL still

You need to check the coolant reservoir to make sure you're not getting coolant in the crankcase.
