So far, I’ve:
1) block tested the engine twice (no exhaust gases in coolant system = no head gasket failure, no combustion leak),
2) tested all glow plugs (all working), and
3) compressio ... |

| @hermano - the cooler having failed is normally shown by oil in the water of the cooling system rather than a leak which is usually gaskets. So I wouldn't be too worried about ordering up a cooler unl ... |

| mjdronfield - I really hope that’s the case and it’s not something more… catastrophic. But the oil cooler was replaced earlier last year because it was leaking oil down the back of the engine.

Update -
I have not yet tested the cylinders’ compressions, but I have disconnected the injectors’ wiring harnesses and cranked the engine, listening to each cylinder. The engine sounds uneven ... |

To test the injector in cylinder 6, I switched it with the one in cylinder 7. Still, I received fault code P0306, “misfire detected in cylinder 6”. How strange, I thought.

| garyRR - Would a torque converter issue also cause a slightly rough idle? I also have a fault code indicating a misfire on cylinder 6. |
