1992 B230F Regina with 199k.
I am getting some metallic "clackety-clack" noise from the front of the motor, almost like a rod knock, going in unison up and down with the RPMs. First suspect the water pump so I took off the belt, and ran the motor and the noise was gone. Easy! I replaced the water pump which looked fine and had no visible problems, and the noise was gone and I was happy.
Now, a mere week later the noise is back with a vengeance! I am sure that it is not the water pump AGAIN, and I am wondering if the P/S pump which is the only other thing on that belt could be the source? Oh, and the noise does go away after the car is driven 10-15 minutes...
