No the pulley that was on there was a plastic one that looks different. Here is a pic of what was on there:
As you can see from the second pic the belt was not riding exactly in the center of the pulley. I don't think that where it was riding was the cause but the fact that for some reason the pulley would rock at an angle to the motor allowing the belt to slip on it.
Here is a pic of the style I put on there and what I believe is the factory style from my experience and what
@ericbphoto says is on his:
@MT_PLS Have you possibly had the valve covers off on that motor to see how much sludge is in there? If it is just varnish your plan is fine but using the Valvoline Restore and Protect with a bunch of sludge it still can plug a filter. I only mention this so you can get extra filters for when you run the Valvoline oil to prevent any oil starvation. 300-500 mile oil filter changes, recommended the lower end of that as a start, to start with with the Valvoline Restore and Protect. It is supposed to do it slower than their old cleaning formula but it has been proven to be problematic if there is any build up of sludge in the motor.
Have a watch of this vid:
