Loss of power, loud knocking, squeaking noise

I have a 94 Isuzu pickup with 200,000ish miles
I was driving on the interstate and suddenly experienced a loss of power. Engine started acting as if I needed to shift sooner. Then a loud squeaky wheel sound started. I pulled over and it turns out that my pump went bad and I was over heating. Fixed that. Have to take most of the pulleys off and they are are in good condition. And none of them wobble. Even the timing belt. But the noises are still there seem to be coming from the timing pulley and such. I've also recently noticed a knocking valve before this but it wasn't effecting anything and it seems to be a ton louder now as well. Am I doomed?
