Hi forum, I had a bit of an anticlimatic day yesterday when I attempted a first start of this D24TIC engine I have been reconditioning for over a year.
See this video as a reference:

Everything on the engine is new or freshly refurbished: block, head (and its gasket), pump, injectors, glow plugs, pistons, piston rings.. everything.
I have timed the pump following the usual procedure I have already used in another engine I have and I am sure it's correct, although I will double check it first thing. I also primed the pump and bled the fuel lines by leaving them disconnected during the initial cranking, until diesel would start spilling from the injector caps. Finally, I have primed the engine with oil before even attempting to crank it.
It seems to me the engine is running uneven and occasionally misfiring. Giving a bit of gas seems to improve the way it runs (so low idle might be
one issue), but even at higher RPMs I feel it's not running right.
Symptoms point me to these possible sources of the issue:
- Wrong pump timing, although just done
- Defective glow plug(s), although all new
- Defective injector(s), although all freshly refurbished
- Defective pump, although freshly refurbished
- Lack of compression in one or more cylinder
My plan now is to check the following, in this order:
- Pump timing
- Glow plugs voltage
- Compression test on all cylinders (sigh)
- Testing injectors
Anything else comes to mind that could cause the engine to run as it does? Any tip is appreciated, I will post results here once I have them
