Ticking noise when accelerating m112 S211 320
Hello,
my car (S211 320 Benzin M112 engine year 2003) has a ticking noise
when i accelerate. When i not accelerate noise disappears.
This noise appears only in D Drive, not in idle (P or N)
In This video you hear my ticking sound.
What can it be??
Gearbox? Manifold gasket leak? Or what do you think??
I changed all lifters and it is still there.

Hello,
chain & chain tensioner i changed first because it makes some noise.
But chain noise is different.
You see & hear:
My chain wasnt streched longer then new one but did made this noise.
(shshsrsrshrhsrhshrhsrsr,....... ;-))
After changing chain and tensioner this noise completely gone.
It was hard work for me to change it but it works ...
This thicking sound when accelerating i dont hear out of car.
Only in cabin with windows closed.

water pump is new. i have a stethoscope and i cant find source of ticking sound.
Problem is that the ticking sound is only under load/at acceleration in cabin hearable.
I think it is a small manifold gasket leak. I will change them both... hope it will go away
