hello @syedfaizan1, hope you're well.
I read your post now as I am researching for a problem I am facing in my car and figured that you and I might have the same problem.
My car is having a rattle noise when driving and after research and opinions from many mechanics, I am convinced it's an issue with my timing chain and tensioner.
Were you going through the same trouble? Did you get it fixed, and how did you?
