What are you getting at? Looks different than yours?
I was just checking/looking at the orientation of everything. Unfortunately it was among a bunch of engines/transmissions and right against a truck, so I really couldn't get a good sideways view. Looking at those pics the alt looks alot straighter then mine does.

You should at least pull yours off, take a look at the mounting to see if anything looks wrong, loose, worn, bent etc. It only takes a few minutes. It might turn up something.

Years ago on my 30th Anniversary Trans Am, I put an underdrive pulley on and couldn't figure out why I kept throwing serpentine belts. I must have gone through three before I took a good look at it. Crank bolt apparently didn't go in all the way so the pulley wasn't snug. Bought yet another bolt and got her square. Fortunately, I didn't mangle the threads in the crank....but look what came out:

No change. Nothing that I can't attribute to random variance anyway. Misfire counts, long term fuel trims, and idle feel remain unchanged. So my takeaways are: either my injectors are fine, or they aren't and the tank added fuel injector cleaner is ineffective. Couldn't say without pulling injectors and measuring flow / pattern and I'm not going to do that

Try a can of Royal Purple Max Clean. One can treat 20 gallons so you’ll need more than one can. You can get at Walmart for less than $14 a can. Stuff works great in yard equipment too
