Knocks in the engine can be defined by the frequency that it happens . If it is a cam follower it would be a constant knock and there would be more than one as if the cam follower or cam lobes are failing . A heavy knock can be a big end or a main bearing failing. Remove the plug wire and if it is a big end the sound will be a lot less as there is no combustion pressure pushing down on the crank pin. When you have got the rod you think it is then remove the plug as well and there will be virtually no noise when running. If the oil pressure is good at idle then the noise may be a broken ring or cracked piston.

Next is the turn signal switch. 3 screws holding it down one on the right side above the key and 2 on the left.
