Default Metal on metal sound

So lat week I changed my spark ifs without breaking 7/8 and the last one (driver side closest to fan) broke, $100 later and 20 minutes with the lisle tool and I got it out and replaced, while doing maintenance I changed the fuel filter, I also added a set of under drive pulleys... (I know too much at once) and since all that I feel like I lost some power and the engine sounds like its knocking a bit with a screeching sound loudest at the front of the drivers side, also the ad ratio seems a lot more active on hard revs,

Could it be pb blaster burning off still? Only drove for 10 or so miles)

All plugs and coils are secured tightly and sufficiently.

What plugs did you use? anything but copper plugs will cause issues. did you use dielectric grease on the cop's? and for future changes I hope you used anti-seize!

Try some spray Belt Dressing for a slipping pulley.

Do your under drive pulleys look like they are wobbling while the engine is running? Is your belt tracking straight?

The belt appears to be tracking straight and no wobble in the pulleys I torqued them down like I was supposed to.
I used ht1 plugs and anti sieze and boot grease the pb blaster is from when I changed the plugs I used it to loosen some of the carbon

Try running the engine briefly with the belt off to see if the sound is being caused by the belt/pulley system. Also, how much PB blaster did you use?

Is the engine misfiring?

No offense, but your descriptions suck. lol. Try to make a YouTube video of the abnormal running condition, whether that's driving or sitting in the driveway (have someone sit shotgun and film if you're driving). That will help give a better idea of where to start looking. Just don't make it with a crappy cell phone.

OEM Plugs are platinum as are most of the aftermarket replacements.

OP, did you clean out the threads and cylinder before putting the new plug in? Sounds like you could've had some broken porcelain in the cylinder. Unless you vacummed out the combustion chamber (Tube and shop vac) that's probably what you heard.

I've considered the porcelain I did blow out excess but did not have a vacuum to remove other waste. If its porcelain now what?

I apologize for the video it was a short notice and needed se stress relief fast ,

I do not have Any cel for a misfire and I'm not noticing a really large jump like a misfire but only90 percent sure.
