In this short video I will show you why your timing chain on your Mercedes with 276 or 278 engine makes noise on start up and what you need to have replaced before engine damage occurs.

I have a sound from my 2012 CLS550. Can I send it to you to help me figure out what's going on? Thanks in advance.

If you are in Toronto Ontario sure I can take a look you can find contact info on malibumotors.ca on certain 278 and 276 you will also need to install non return valves

@bobtech1013 none return valves are the check valves right? Also do they cam position or plate leak onto wiring or harness ? This is fixed by pulling timing cover and everything correct?

@@scottp6761 the o rings for the camshaft actuators do leak you can replace the o rings for them also make sure the pintle on the solenoid is free and moving in and out easily also the top section of the timing cover can be removed and re siliconed

I have a slight chatter on start up and it disappears after 3 seconds. 2014 cls 550 with 25k miles only. Im changing oil to a higher viscosity 5w40-50 and adding ester oil additive. But is it a ticking time bomb? It doesnt do it on cold starts. It does it after its hot. I turn car off and let it sit for 30 min to 1 hour and then it will make the noise. It almost sounds like valve chatter or something or lifter. But idk

My theory was no oil pressure and then it is fine. Engine runs great otherwise. I'm concerned but not freaking out "yet"
