I asked my mechanic to replace the fuel filter of our L300 FB. I noticed that there's a sudden increase of engine noise. btw, the new fuel filter is bosch. i also add 2T on its diesel and i've been doing it for 6 mo. already.
what do you think is the problem? is there any problem with the fuel injection?
thanks

Was the air filter replaced also? A clean air filter on a diesel can make a noticeable noise difference.

What was the viscosity index of the oil you used previously? And the new one now?
A lot of fake Castrol products in the market now, I hope you're not a victim.

if previously yan din gamit mo and walang noise, then its not fuel filter that could be causing it...
pero if that's the first time for you to use the bosch brand then it could be the new fuel filter...
possible reason, fuel filter not authentic, fuel filter part number is not the right one,
if the fuel filter is authentic and is the right part number for the 4D56,then the fuel filter is good, the engine noise may be from something else that might have just coincide with the time you change it to bosch....

was the fuel system bled after? baka hindi properly filled with diesel yung filter so pinasukan ng air yung fuel lines. this will not happen if your mechanic filled the filter to the brim. this trapped air can cause some of the injectors to miss prime causing uneven engine run. may "tik-tik-tik" na sound ba, especially if coming from only 1 or 2 cylinders? pump up the fuel pressure using the manual pump on top of the filter then bleed off each injector by loosening the high pressure fuel line nut until only fuel comes out.
