Hi
I have a 2011 ford falcon BF
it has started making a really bad knocking noise
The noise is worse when it's cold but still there when it warms up
It was making a little bit of a ticking noise
Now it's started making a really bad knocking noise
I have posted the video here

I am really worried.... I read somewhere jt could be bent rod?
I have lubricated the tensioner pulley as ppl had suggested
Without my car I lose my job and I am worried it's going to die any minute

Any help is really appreciates

Update . It almost goes away when the car is hot

you have more of a chance here - http://www.fordforums.com.au/showthread.php?p=6888875#post6888875 of getting an answer to your question. with my BA i did have a [what i thought] bearing/knocking/grinding noise .. that turned out to be the gearbox[which was replaced]. this may/may not be your issue. best get it checked out before it craps itself.

A knocking sound from your car's engine isn't always indicative of a serious problem; it could be as simple as low-quality fuel. Most cars have a knock sensor that detects engine knocks and alerts the ECU to correct the issue. Thus, a knocking noise could be caused by a faulty knock sensor. basketball stars

Could be a noisy hydraulic lifter... could be a lot of things...
