pcv valve wont work properly
A bad PCV valve can cause the engine to smoke. The valve is easy to change in most engines to correct the problem.
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.
