Between the last few oil changes my oil consumption has been getting worse and worse. The last time it took 4 quarts over 3000 miles to get to the next oil change. I don't see it leaking any onto the driveway nor does it look like it's burning it in the exhaust. From searching it seems like it's most likely my pcv valve. My question is what exactly does the pcv valve and where would it make all this oil be going? How hard is it to replace is it something I can do myself fairly easily?
