If it rattles , then it means it's not stuck and is good!!!
Remove the PCV valve and hold it near your ear. Shake it up and down. If it rattles, it is OK. If you hear nothing, it's time for a replacement.
A bad PCV valve can cause the engine to smoke. The valve is easy to change in most engines to correct the problem.
check your PVC valve, shake it and if it rattles,its ok.then check your hose and metal tube to see if its clogged.
The PCV valve is located on the top of the valve cover. To test the PCV valve, start the engine, pull the valve out of the valve cover and put your thumb over the hole in the end. If you hear a little click, then the PCV valve is good. If there is no vacuum at the hole, either the valve is bad or the hose is bad. To see if the hose is bad, pull the hose off and put your thumb over the end. If there is vacuum, replace the PCV valve. If not, replace the hose. It's important to note that PCV valves are sized for specific engine applications. The wrong PCV valve for an application can flow too much or too little air causing driveability problems.
put a new PCV valve in if it's bad.
Disconnect it from the engine and try to shake it with your hand. If it rattles it's probably okay.
I have read that a bad PCV Valve will contribute to gunking up your Throttle Body, which could lead to irregular acceleration issues. I am certain that there is more to a bad PCV Valve than that, as this is an Emission Control item, but hopefully someone who knows more will chime in. SUBMITTED: Friday, 03JUN11
yes. if the valve is plugged or stuck closed, oil can be sucked into the intake through the pcv breather.
