My attempt to fix to good condition my Mercedes 190D turbo 1987 Warm engine sound after pulling and cleaning prechambers, rebuilding injectors with new firad injector nozzles. Still sounds a little loud and uneven. Does this sound like a healthy engine to you? It seems loud, but it is my first diesel project car. I don’t know what they supposed to sound like. If you have similar car with OM602 ...
Is there a procedure for reinstalling the timing chain tensioner
Thanks for your help, today I changed the lifters on my om601 , the same procedure . Everything works and the nocking voice is gone.
I hear 2 sounds. 1 or 2 bad valve tappets and the chain guard chain tensioner or something
Check the pre chambers.. They wear out..
Hola, desde Arg. Las precámaras son solo cámaras para que dentro trabaje el inyector? O poseen una bolilla con un resorte? Que trabaja con los tiempos de inyección? Esa es mi duda, muchas gracias!
As far as I can tell the sound is slightly better. I have not touched it since last video. I’ve been trying to figure out what to do next. I love it, but it is mostly my project car so I am not in a rush. I am thinking I might check injector pump next or look at injectors again. I did compression and it seems pretty good.
I have the same problem. But i am right or the sound hasnt improved a lot? Maybe the camshaft? Thanks a lot, im about to perform the same exact repair and your video has given me a lot of clarification.
Do you still have that car? And are you did find reason loud ilde?
Yes, camshaft was one tooth behind where it needed to be. Basically camshaft and crankshaft timing was way off out of alignment (by one camshaft tooth) and yet my injection timing was perfect. After I fixed timing car was running perfectly and sounded 1000 times better! However, about 10k miles later I've noticed that my head gasket was leaking (exhaust in coolant) so I took engine head off and that's when I realized that someone replaced head gasket and did pretty bad job. Surfaces were not cleaned well and had pretty bad scratches. That's probably when they messed up cam/crank timing... I am planning to assemble everything back in spring/summer and will show some videos...
@@countlesshobbiesmk2273 Thanks for the comprehensive answer! Nice to hear that the cause, however, was found. I can't wait for the next video:)
It can be also thé vacuüm pump. Front of engine.
Thuis sounds for me like bad hydraulic Valve.lifters This engine have 10 hydraulic valve. Lifters And this sounds for me like bad coper rings in the fuelpump. 5 o rings. Thank me later.
Sounds fine. Maybe not getting enough fuel ? Check your filters like ore filter and tank screen
Any updates on this car and what fixed your noise?
Super cool car! I have the 300D with this same engine. That smaller car must be a rocket ship!
Its pretty fast and fun car. No problems in modern traffic or on the highway. I tried timing 0-60 mph and got about 11 seconds.
@@countlesshobbiesmk2273 I get about 11.5 in mine, so pretty close.
I finally figured out what the issue was and why the engine is so loud. I will post video in a few days. Hope it will help someone else...
Still waiting for the video
What was the issue? I have a 190d too and it sounds like yours in this video
Чё так громко работает мотор
Расскажу в следующем видео 😉

Have you checked the belt tensioner? Sounds somewhat like hydraulic lifters. You can check them by removing valve cover - and you can also check chain stretch with valve cover off. If chain is stretched over 3 degrees you have to advance the pump timing. The other question is who rebuild your injectors. Maybe he set wrong (too high) injection pressure? It should be 135 bars. From my experience if pressure is lowered the engine is more quiet with no negative consequences (minimal 100 bars for nonturbo and 120 bars for turbo). Moreover I remomend geting monark nozzles, or at least bosh. Firad is crap.
i have the E300 D. Same engine I believe.
i prefer 190d
Put some Diesel Purge in the tank, about 5 cans.
The little diesel filter is fitted reversed the engine needs more fuel did you change every filters even the one under the fuel tank?
I changed small prefilter and main fuel filter. I didn't change the fuel tank filter yet. Will check it.
What about lifters?
Yes, I am planning to check lifters next weekend.
I replaced all lifters. It sounds a little better.
