If its moving you're good. Why not just delete and retype instead of apologizing for the caps lock? Even your apology is in capitals. Kids these days...

Cleaning them with brake cleaner is good, it depends though, how many miles are on it? They play a fairly important role.. venting crank case pressure.(PCV=positive crankcase ventilation) Its probably good practice to replace them every 30-60k miles, preferably with a OEM one, the springs in them will get weak over time and they will not function correctly. If one gets stuck closed, it could lead to oil leaks, if one gets stuck open could cause a vacuum leak and lead to misfires. Just my 2 cents.

Ok. Please strike my comment about the kids from the record.

If yours can be replaced for <$6 as mine was, why not replace/renew the part that will last 100k miles? It's the only way you'll know for sure that it's working PROPERLY.

I have always checked mine and never had issue. Only thing I can think of that has kept one from going out on me is I use 4 oz of redline si-1 once a week, drive mostly interstate and use only synthetic oil which helps with burn off. I do check it and throttle body every oil change. If you throttle body has lots of gunk you might need to check both pcv and egr also.

Its not just the cleanliness aspect that allows the the PCV to function properly its the spring inside. Like any other spring it weakens with use. Replace.

Unless you have a PCV like the one in my 2013 5.3L GM in my Silverado. It is not a replaceable PCV valve, it is part of the the valve cover itself. I suppose one could replace the entire valve cover.

I have a 96 Camry that started using a bit more oil the last oil change. On a hunch, I pulled the PCV this past weekend. The Fram PCV, that was replaced LAST YEAR, was shot. This is the 1st PCV I've had that has completely quit working. I replaced it with a Puro PCV. What was odd, however, was the Puro was at least 50% larger than the Fram. I actually went back into AAP to do a 2nd cross check, and the Puro and Fram were correct for my application. Kind of wierd...
