First rifle and scope I got low rifle mounts but It’s very low, I don’t know if it’s okay or not if anyone has advice?

So for starters this hose is clamped off I think it’s the pcv hose if anyone can confirm that, and the battery also has some sort of parasitic drain, the guy before me put aftermarket lights in and I’m thinking that’s the issue what are some things to look for?, example the front hood light has wires split out of the hood lights the left is connected to the aftermarket lights but the right has two wires split open laying on the chassis in a little pool of water, is something that small gonna give it a drain and should I go around the whole vehicle looking for stuff like this?

Trying to figure out what’s causing this noise I really feel like it’s a lifter tick but I’m not a mechanic this is my first vehicle I’ve had for a week, I want to do these repairs myself as well, as long as I don’t have to take the engine out, even if I have to replace a camshaft I can do so just by lifting the cam covers right? And what else should I replace if it is a lifter or rocker?

Why are the returns so choppy even with the transducer in water?
