You guys happen to know those O-ring sizes ?
 
The PCV Valve itself never wears out. I dunk it in mineral spirits to remove the oil and it's good as new.
 
If I remember correctly, I broke the MAP sensor housing (that black bracket) when I changed mine (it was good and stuck) and I was glad I purchased that particular kit. I'd go that route, personally.

Bigger and smaller. Take them out, measure them, put them back in, drive to local ACE hardware, buy them, drive home, put them in. Or buy on Amazon for $15.07 or RockAuto for $15.88 and save time and gas money.

I tried measuring the small one. It came out with a slight oval shape which threw me off. And then the cross section measurement is never easy either. Is it 1/16 or 3/32 ? I need to find a new one to measure.
