Hello everyone, I am looking for some insight into an issue I am having with my car. I appreciate any help and thanks in advance if you take the time to help me out.
It may be more than one issue but here are the symptoms to the best I can describe with my very limited car knowledge. The following will get you to where I am at, learning as I go. Now I come to you for assistance in personally fixing this:
Car is manual, starts just fine. Clicking noise on and off that seems to be consistent in BPM after changing my fuel filter today. I did not notice it go up in click rate during acceleration, although it is very hard to hear over the muffler the car has...
You can refer to this youtube link of a 12 second video. You will hear the noise and see me point to where the noise is coming from. You will also notice that I point to the left camshaft that is not spinning and I can spin by hand. that worries me as well, I am currently looking more into that

Acceleration: When I speed up, notably in gears 1-3 from 1000-3000 RPMs, the car is very bumpy and hesitant but gets up to speed. Almost as if a fuel flow or related electrical/air/fuel system issue. In higher RPMS and Gear 4/5 it is majority smooth sailing. Sometimes it has better flow than others but it is now getting bad beginning the last couple days. I should also share it got much worse after a friend borrowed my car. I said check the oil and he overfilled it topping it off. I got that out a couple days later as soon as I knew. Maybe and probably related, but maybe not.
Today I changed the fuel filter, and began noticing the click directly AFTER the change but is possible I just haven't heard it since these symptoms increased. Symptoms since fuel filter change still exist, but may have helped a minor amount. It is hard to tell because the flow of power during acceleration is constantly different, sometimes flowing well and mostly not.
Next I am going to test the fuel injector via screwdriver test. Also about to go buy a new engine air filter since I don't know how old it is and it looks terrible. When I have changed air filter and tested the fuel injector I will update the thread on engine performance.
I guess this is where I am at. Questions: Is there any insight from my description that leads you to a specific problem creating my acceleration issue? What the hell is that clicking noise? Do you think it is fuel, air, or electrical?
THANK YOU SO MUCH. I look forward to tackling this as far as I can and learning about how this system truly works.

Those engines are known for valvetrain noise, not usually that loud though. I would get that one in to a subaru shop, I dont think this will be a diy fix. BTW thats your a/c compressor youre spinning.

A/C Compressor makes sense for what I was spinning, fan went out a few weeks ago so glad to know ha. I'll try and get off early to take it in this week for diagnostics. Thanks, any other test ideas or insight in the meantime?
