you can see the valve on the fuel injector. it is on the passenger side of the car and to the front of the injector.
its the needle valve inside the injector opening and closing
I want to clarify if you are asking if you can blow air through a fuel injector? If this is your question, I am not really sure what you are going to gain by trying to do this. A fuel injector has a tiny valve inside that opens with an electrical pulse from the PCM. Even if you could open that valve, the passages inside the injector are the size of a pinprick. There is nothing to be gained in trying to blow air through an injector. You will not even be able to tell how much air is going through the injector, and how much air is going around the injector as you are doing this. If the injector will not clean up with injector cleaners, then it will require replacement.
It should be on the top of the valve cover connecting the engine and the injector.
For valve clearance of Volvo d13a one needs to remove and re install injector cups.

Should be hanging around where the valve cover is. PCV valve is on the intake from driver side it will be between the first and second fuel injector hope this helps

You may have a bad fuel injector. Try to single out which cylinder is dead, then remove that spark plug, if the plug is clean and dry you have a faulty fuel injector.

There are several piezo crystals in the injector in order to achieve the required needle or valve lift. When an electric current is applied piezo crystals, they expand or contract. Since piezo elements are lighter, they respond quicker. This lets the injector valve switch five times more quickly to meter the fuel and control the injection curve more precisely.
