What is the symptoms of a bad PCV valve?

Generally speaking the symptom of a bad PCV valve is a buildup of pressure inside the crankcase. If it is bad enough it can cause the engine oil to come out through the dip stick tube. If you pull the dipstick out and hear a release of pressure that is probably an indication of a bad PCV valve. The common way to check the PCV valve is to take it out and shake it. If it has a rattle then it is supposed to be good, no rattle it is assumed to be plugged up and no longer working. I am not certain if that is still a valid check.

Where is the pcv valve on 1994 Toyota Celica?

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.
