Default Help with a diagnose.

Rather than read all these threads on this matter i decided to take a few vids to see if you could help me diagnose a few problems. The first video you will see i decided to take was out of nowhere the engine got extremely loud all of a sudden.. I was thinking maybe the belts were going bad or what not..Mind you idk jack about drivetrain w.e as u see its stock lol..Just the normal clank clank..the continuing sound u here that is in the background and that is not from the car.. This clank is so loud i cant even hear the exhaust that well..I thought maybe a leak or what not but i didnt find anything...

The second video was one just for the clutch.. I do believe it is still the stock one and is roughly about 70K and i bought the car used some 2.5 years ago.I know i am bad lol...It seems that it makes a distinct different noise than the other gears. It is only when i shift out of 5th it makes a loud pop. Maybe the throwout bearing but idk..Just hoping you guys could show me some insight before i make a regret of getting rid of the tc..Sound in the background is a jumbo jet..

Thanks for any info and yes i know it is dirty..

in the first video, it sounds like you have a bad valve tick. and the noise it makes is the sound of the cooling fans coming on to cool the radiator, and since they are electric, they put drain on the electrical system and make the engine idle higher.

and your shifts are noisy, but i don't know why.

in the first vid it sounds like a bad alternator or ac comp, maybe a bearing going out possibly. The second vid is just the usual clanking from the shifter linkage.

ok thanks for the input, it seems that recently with the whole clutch situation that it likes to give me fits, more so recently that when i try to throw it into 5th it would fight me..Other gears are solid tho....

How would u go about fixing a bad valve tick if that would be the problem? i was trying to find some stuff online and they said that you could put some stuff in with your next oil change..

took the car for a spin today, and it seems like when i get it into gear and give it a little gas.. the sound it seems like from the alternator gets louder and then it fades away..its like around the 2000-3000 rpm mark..
