Within a couple of days my car began to smoke terrible (thick grey smoke) and idle very rough. There is no oil in the coolant or coolant in the oil. The radiator hoses are not pressurized when the engine is cold. Also the coolant level has not changed and there are no fuel leaks. I've changed the plugs, the camshaft timing is good, ran it with fresh diesel then ran with diesel injection cleaner. I removed the injectors and viewed the spray pattern on each and they look good. EGR valve is not stuck open. All ball pins in the prechamber are intact. The exhaust tappets have only about 1-2 mm play. I ran a compression test but I'm not sure what the limits are. The highest was 460 psi and the lowest was 410 psi. The other four were 440-450 psi. Thanks again for all your help. Ken Ken, Does the problem still exist? What about the EGR valve, which can stick open? Your compression is excellent, indicating the valves are seating properly, and the hydraulic lifters too. Did you remove the access panel on the pan to look for physical clues. Your injection timer, which drives the Injection pump, could have come apart, that is the only way I see the fuel timing changing without breaking the chain. If it did, the springs are probably in the pan.
