HELP!! Weird noise from the engine!!
 

Hello i'm new to this so sorry if i posted this in the wrong area but i am having a couple of issues with my 2004 Mazda 3 Hatchback 2.3. I am a college student that doesn't have alot of money to blow so i'm trying to see what it could be without spending tons of cash to find out... anyways i have a link to youtube since i cant explain the noise.. And there is a noise coming from the tire area im not sure if its the disks or what but i have changed the tires and the brakes... If anyone could help me i would really appreciate it Thanks so much!!!

Take off the vanity cover and you should hear it better. If you unplug the left VTCS valve solenoid while the car is running the knocking should stop. This problem is kind of common if that is what's causing it. If it is, then you might have to replace the solenoid or the VTCS valves themselves.
