I suggest you keep your original 5k engine. The cost of a 2nd hand 2ct plus other additional expenses cannot justify your expected fuel savings if you convert to diesel. Try to do some calculations.

And if modification work is poorly done, you will have to live with it.

sir diesel dude, would like to know if you perform services on mercedes benz
s too. i currently have a w124 250D and im experiencing some engine noise (as compared to other people i know with benz diesels which are very quiet) and a weird vibration from the fuel lines. liek when i touch the lines, then seem to be a tapping feeling inside them.

Baka mababa lang ang setting ng low idle rpm.

Or baka worn out na ang engine supports.

1) The hoses on your fuel filter may have been connected the opposite way? There is a one way valve in the filter base.

2) You may have a suction leak?

3) Absence of +12 volts to the injection pump solenoid or a failed solenoid coil?

4) Faulty injection pump.

Yan yung recommended fix kasi sabi mo ayaw mag pump ng fuel.

Pa-check mo ang wiring, glow plug relay, or preheat controller kung walang kuryente sa plugs.

Good luck.
