So, I have replaced my valve cover gasket, as well as the spark plugs, in a 1003 Ford Tempo (apparently most of these have died already!)
However, after adjustment, I am getting a sound. I do not particularly remember this sound from beforehand, and I don't really know what causes it.
Here is an upload of the sound: abnormal noise
I apologize for the low quality of the recording, but the "back and fourth sound" is somehow louder in real life, at least a bit.
Thanks for any help.
