Reconditioned engine first start, running rough
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: https://www.youtube.com/watch?v=qvTZkiHrkUc 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 Last edited by coconup; 11-06-2022 at 11:22 PM. |
