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)
