I was driving along and it just went downhill real fast, smoking, sputtering etc. No comp on cyl number 5, smoking out the intake ports. From what i could see its an injector problem. The bummer is mine happened about 2 weeks after i finished doing a mech pump swap, big turbo etc. My plan of approach is to pull motor, swap in a good piston and rod, get the valves for #5 worked on, smooth out the damage on the head, put 'er back together. Luckily my holset hx35 didnt get damaged by the metal chunks. Probably going to pull my motor later today.....The number 5 cylinder seems to be the problem cylinder. You might also want to do the Diesel Meken thermostat bypass to number 5 cylinder as well. He has a you-tube video on this, I do this to all my conversion engines. DieselpumpUK also just came out with a smaller water pump pulley to run the water pump faster to improve cooling.
editt:: my damage is actually isolated to just the #5 so i guess i got lucky there, my motor still has all its crosshatching after 200k
If it is an injector issue then why would coolant flow affect anything? Doesnt make sense. Unless injectors fail from poor coolant flow.
Coolant also cools the cylinder temperature. That is why when EGT goes up so does water temperature. Number 5 cylinder seems to be the worst one hence the water bypass. The hotter the cylinder temperature the hotter the prechamber is. Although the prechamber is failing from an injector dripping on it after the engine is shut off, water temperature plays a part in this. The water bypass eliminates a hot spot.
