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.

Any ideas??

Anyone with same noise?

maybe the chain is stretched.

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.

IS Your water pump okay? Get a stethoscope and use it to decipher where noise is coming from....

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

That isn't going to make a difference. If it was that you wouldn't ONLY hear this when vehicle is moving/accelerating.... It would be constant if it was a vacuumm leak.

find a lift, put it in dyno mode, drive vehicle on lift to duplicate noise.... GL
