Well, come to find out the knock was probably originally caused by the Lash adjuster "Pumping Up" and causing it to make the valve have negative clearance and collide with the piston, im not sure if it is bent or if it is broken, the valve I believe is bad is the intake on piston no 1, if I turn the engine over with a 1/2in rachet, it is very hard to turn when it hits TDC between exhaust and intake, if i take a screwdriver and try to push the valve down when it is stuck on TDC, it will not budge, but the rest will. So will I be able to replace just the valve or will I have to redo the valve seats to? I added a video so you can hear the noise. Also check out my other videos when this one ends.
Here is what it used to sound like
