This is a follow-up on the klatta-klatta noise that our C36 is making.

We've noticed that it only makes it during idle, and it sounds like its coming from the timing chain/cam sprocket area.

Via the diagnostic port, we can activate/de-activate the cam-advance solenoid.

When activated, the sound is gone.
When de-activated, the sound comes back.

Does the intake cam sprocket assembly get noisy, or could this be chain stretch?

Could this contribute to no high-end "umph"?

Our only testing is with the stock 300TE exhaust (single cat, single O2-sensor), so we are now fabricating a dual-cat and dual O2-sensor free-flow exhaust that will mimick the C36 exhaust system.

Any other ideas?

Thanks,

Neil,
Though I never detected the sound you described, my 95 C36 did have some problems with the valve timing/advance. Message Donnie/Benzmac in tech help, he should be more familiar with the specifics. Mine was not advancing the cam as it should and there was a VERY noticeable high rpm power loss.

Hope this helps,
Lee

Sadly to report the klatta klatta noise is an abnormality. The service advisor said that it's the timing chain or something of the other...All i know is that it costs Mucho denero! Crud, and i just paid for 4 new rotors and pads! All this within a week, my wallet can barely stay afloat.
But then the road beckons me to quickly get back on!

Well, the klatta-klatta noise is still there. We re-installed the chain tensioner (it was too tight), and reset the timing chain (no stretch) and it's still there.

Anyone else have any ideas?

Thanks,
:-) neil

Take those baseball cards outta your rims.

hehehe

I do notice that my 97 C36 also has klatta sounds when idle. Also I have been to every MB service scheduled and the idel isn't what it use to be. I use to have to think twice before knowing that the car is on...but now I KNOW the car is on.

Oh well.

standard fair for the C36 I am afraid.

Hey guys,

I don't have the noises that you guys, have.
Although I did have some noises before, but then I found out that the belt tensioner need to be replaced.
So I brought the car to the dealer, and they replaced it for free (it was still under warranty)
Probably you guy want to check out you tensioner as well.

Yep, i use to have the klatta noise as well, but M-B service technician discovered it to be a bad timing advancement thingy! It affected the high rpm power. It's fixed but now there is a faulty coil!
