Could I put the HEGO ground on the firewall where the braided ground strap connects from the engine? Would it still work?

I dont race my car. never will. I feel my U/L rear control arms bushing have seen better days. Since i dont race would it benefit me to replace the whole control arms or just the bushings?

when i was underneath my car i noticed a couple broken wires on my o2 sensor wiring harness going to the driver side banks o2 sensor. looks like it got burnt and covered in oil. Would that possibly be the cause of my engine picking up code 41 and 91?

Now if I would pull the pcv valve out of the grommet would i be able to put my hand near the hole while it was running and feel a suction? or would it blow out? or nothing at all happen?
