1994 Mazda Protege 4 cyl Automatic 152000 miles
I have a 1994 mazda protege and the engine has a really loud knocking sound.
I was told by one person that it was the cylinder but told by another person that it was most likely a bad valve because when the car is running you can pull any spark plug out and the knocking doesn't stop.
I really want to find out what this knocking sound is?
