I'm not sure these are normal noises coming from the engine. One is the fuel pressure regulator. it's very loud. Secondly when the engine revs up, it sounds pretty "ticky"
Car also burns oil :/

Those sounds definitely aren't normal. I'd start by checking vacuum lines to the fpr and the vacuum diaphragm under the manifold that controls the butterfly valves inside. If they are connected I would replace the fpr and take apart the manifold and examine the butterfly valves for damage or buildup causing them to stick.

As far as oil consumption you should check your pcv valve. Ive been also changing my oil and adding engine restore additive. I have noticed a slight increase in mpg, power, and lessened oil consumption.
