My 1989 OM602 engine with 200K on it was very quiet when cold but as it warmed up a fairly loud tick tick tick comes about. I changed the tappets, no difference, new injector, regular oil changes with flushes and diesel purge no difference. Couldn't find any garage to take it on so now in the process of changing the engine. Might seem extreme but cheaper to find another engine than pay silly garage fees.
Hello. Well, I have the same car, year 1993 with 275.000 km on the odometer, but could have more. I had the about the same noises a couple of months ago. There is a clicking noise that maybe caused by hydraulic valve lifters. There is a second noise on the background which frequency seems to be half or one third of rpm, and that sounds like a soft beat and blow, alltogether. Identical to the one you show in this video. To remediate the noises I changed the valve lifters (all of therm) and changed the chain tensor. Now sound is a lot less, but the second noise still shows after the engine turn hot. If I rev up the engine for a while, the sound dissapear. May come back again later. With a cold engine the sound is not present. Only after the engine gets hot. But I still can make it dissapear revving up the engine (over 2000 rpm). Other possibilities I am considering to be causing the noise: 1) Alternator. 2) Vacuum pump. 3) Rubber strap of the fan, alternator, etc. on the engine. 4) Fan clutch. 5) Poor seal on vacuum hoses causing some trouble somewhere. 6) Low pressure on oil. 7) Dirt on injection pump and pipes, injectors. Next step I will make a Diesel purge. I will prepare a wood stick to put on my ear to help find the place where the noise comes from. The oil pressure gauge starts well, mark full with cold engine. After getting hot it lowers one third down. Sometimes it vibrates. There are no visible leaks of oil. The car runs very well, last trip at 110 to 120 km/h yield 12,5 km/liter which I think is very good (two full tanks). No smoke, no oil loss. I also accelerated until 160km/h easily a couple of times. Going up a hill. You have a lot of experience with this cars, combining it with the information I give to you now, and the real cause of the noise you found on the car of your video, you may assing probabilities to any of these 7 possible causes. By the way, what was the problem on that car? Thank you a lot for sharing your experience with us. Best, José from Chile.
Collapsed lifters, the OM603 is known for this, just did mine couple months ago, exact same noise but also I would investigate the vacuum pump, sounds like another noise too.
hello friend ! finally, I did get all the lifter out and there was one worn out. there was a kinda slot on the top, made by the camshaft lobe, like it was not turning! so I'd replace it with a new INA one. I dismantled the other one, all a part and they were very clean! but the trick is that there is a re- bolt order for the camshaft ! unfortunately, a broked the camshaft in two pieces, so I have to order a used one on E-bay!!! now: no more tiklin and very happy ! thanks for sharing all of your video !

Hi Mr Diesel. Thanks for all your videos. About this noise, I have the same when you rev the engine at cold temp, but in my engine, at cold and warm temp, and only when engine is around 1000rpm. My engine is OM605.911 from year 95, with 240000km. I bought past week so I will do all basic manteinance next week (engine flush, oil, air, steering power and fuel filters, Petronas 5w40 oil change...). Belt tensioner shock absorber was replaced two years ago. Which was the solution of the noise? Follow with these great jobs. Thanks
It just sounds normal to me for these engines mine got 400k on it and sounds same but could be wrong over a phone video the sound would have to hear in person.
Hello. I have a W124 250D from 1990 and I follow your great channel. Thank you for sharing all these useful info with us. I had a leak on the 5 delivery valves of the injection pump. So, I bought the dedicated tool and I replaced the copper and O rings. It solved the leak but now I have a strong clicking noise. I checked the oil level and I also removed the cover of the hydraulic valves tappets to check if the tappets have to be changed or not. Conclusion: the tappets are ok. This is a good news but on the other side I still don't find the cause of my clicking noise. Do you have and idea about what could be the reason of this clicking noise? Thank you! Armand
I have the same noise on a OM601 , Only on a cold engine tho ... I have replaced all injector nozzles, diesel purged the engine , changed the filters and yet i still have it. My guess is either the Hydralic Lifters (esepecially if its driven with bad Oil before) or the VacuumPump. If you found a solution that'd be great :)
It´s the Hydropushers. I have two W124 - 200d and 300d (no Turbo). I had in both my Benz this problem - then I bought LiquiMoly Hydropushers Liquid and after 1.000 km no sound at all. All OK. I live in Germany.
@@oleggordey This is coming from the lifters. It is a rather soft noise. My brothers om602 had bad (but new) injectors and that sounded like a rattlecan. If the noise is very harsh (like a rattle can) and is most pronounced at very light throttle at low RPMs and it goes away when engine braking, than it is the injectors.
this is mersedes i hev w203 is very ned car olly ny merseds now do bed cars not gud mesedes confront 1992 the best mersedes i thik now mersedes heve sow much milion euro en don do more best auto .dont lich more tow do gud auto.
This guy the way he said hi creeps me out a little. I think I will subscribe.
My reason for subscribing
I got same problem with my 1990 Mercedes w124 300 diesel engine.. It's really nice to watch your videos, I learned something. Thanks :)
you are welcome….

Thank you for your clear videos! I think you explain it very well. I would like to see a video of how to check for timing chain wear.

Thanks for sharing ..
Had the exact same problem. The cam timing is one tooth out.
Did you ever end up finding out what the knocking ticks were caused by?
I have a 1990 300d that does this also. What I do is close the hood and turn up the radio.
cheap way to deal with it ! Awesome….
The tippers need to be adjusted. You don't need to do that except that clicking really annoys you.
@@VideoAmateurLuxembourg the tappets on this engine are hydraulic and self-adjusting.
Could you please upload a video of how to change the hydraulic lifters?? Thanks and greate videos by the way!!
in future..when I have car with that problem…this car was sold….
Yes i would also like a video on this please.

Buenas tardes saludos desde Cuba mui bueno sus videos gracias por sus enseñanzas maestro
I would rather repair that huge dent on the left side rather to worry about that normal clicking.
Great videos! I would love to see some more about the '99 e300 td
Stefan Prenkocevic when i will get one to work on, i will film it for sure….
hello, how did you deal with this fault? what did you fix my 124 3.0td is also like that ...
It just sounds normal to me for these engines mine got 400k on it and sounds same but could be wrong over a phone video the sound would have to hear in person.
If benny hill had another character .lol love him and his knowledge..
hello friend, i have the same problem on the OM603 TURBO, the same sound and restless operation as in your video, please tell me what the problem was
try carburator cleaner on your injektors hven the eingin is going ..u vill see..

Hi, I have a W124 E250D with OM605 Engine. It has a rough idle, can you help suggest what I should attempt to fix?
The engine should not shack like yours does when cold.
I love this guy
I have the same noise on a OM601 , Only on a cold engine tho ... I have replaced all injector nozzles, diesel purged the engine , changed the filters and yet i still have it. My guess is either the Hydralic Lifters (esepecially if its driven with bad Oil before) or the VacuumPump. If you found a solution that'd be great :)
VenKKi Makaveev Thank you for sharing your experience with all of us !
it's definitly the lifters. been there, done that, several times :)
It´s the Hydropushers. I have two W124 - 200d and 300d (no Turbo). I had in both my Benz this problem - then I bought LiquiMoly Hydropushers Liquid and after 1.000 km no sound at all. All OK. I live in Germany.
krzysioo22 Thank you for sharing !
+krzysioo22 What is this Germany you speak of? Do they know much about making a good Mercedes Benz?
you repair them only changing the oil?
Jak sobie poradziles z tym stukaniem?
Maybe exhaust manifold leak.
Does anyone Have a solution for this problem? May it be the Diesel injectors??
check my other video….you will see the answer.
which video?
@@dieselmercedes7507 we don't find it !!!
hydraulic valves adjusters have gone bad . replace them tick sound will go away simple !!
Thank you for sharing...
@@oleggordey This is coming from the lifters.

Hydropusher valves 99%. I replaced all was well.my engine is similar to your
Rust G I think you speak about Hydraulic Valve Compensating Elements, test, they are source of all kinds of noises many times….Thanks.
YES
nice to watch your channel
Thank you.
I’d say this is the fuel filter. Cheap to check and fit. Always try that first on an old beast
did anyone else hear an air leak.
Неробе свіча накала
this is mersedes i hev w203 is very ned car olly ny merseds now do bed cars not gud mesedes confront 1992 the best mersedes i thik now mersedes heve sow much milion euro en don do more best auto .dont lich more tow do gud auto.
Rod knock. That engine is toast.
That is not rod knock.
