Why does my DT 466E engine have low oil pressure?
If the injection control pressure is low it may be the injector o-rings, a defect in the injector itself (poppet valve) or worn out pump. The symptoms of a low oil pressure to the injectors will be low power especially when hot, high fuel and oil consumption and blue exhaust smoke especially on start up.
Is the dt466e a lack of power?
The second you put it in gear it has no power. 20 mph top speed. Tested fuel pressure today at the filter. It is only reading 40 lbs at idle and it dips down to 34 or so when accelerating. I assume this is a fuel problem, but what is the problem and where do we start? Thanks in advance if anyone has done this one.

Is the DT466 loss of power really that bad?
It had very slow acceleration and it would die quickly when going up hills. it seemed to struggle heavily on hills actually. The clutch is fine, just got adjusted about a month ago, no smoke, just low power. Air filter is clean. Oil pressure is good. Temp was fine. No lights came on.
Where is the oil pressure regulator on a diesel?
There is a pressure regulator and a relief valve that control the oil pressure. I believe they are both located in the front cover in your engine. I have a hard time believing the pickup tube would have failed. Click to expand… Pulled the tube and checked it. It was fine. Pulled the engine oil pump (on crank) and it looks worn.

Why does my dt466e take so long to start?
The high psi oil system, in a dt466e you have high psi oil that fires the injectors, and sometimes the pump can actually bleed down overnight causing it to take forever to start, the only way to check that will be let it sit overnight and there is a temp sensor in the front cover/ drivers side . it is right in front of the oil/fuel pump.
What should fuel psi be on dt466e International diesel?
Usually when we get no start cold but fires and runs after using ether it might be injectors, but you need to do the fuel checks I posted and let me know. If you don’t have a fuel psi gauge, autozone loans them out. I like to have around 60psi I have seen them run ok above 45psi.
Can a 2004 DT 466 E start on its own?
I’m working on a 2004 DT 466 e with the variable turbo that won’t start on it’s own. The fuel pressure at the manifold will only get up to about 20psi after exteneded cranking. I replaced the lift pump and it didn’t change one bit.

Why does my DT engine not start well?
The high mileage on this DT engine was a factor and we changed the HEUI o-rings as well since that also directly effects starting. The o-rings separate the oil from the fuel around the injector and if one of them fails this will also cause poor starting among other problems.
Why does my 1999 IH dt466e keep dying?
I have a 1999 IH DT466E that will not stay running. It will start right up and then run from anywhere from 30 secs. to several minutes. It then dies, but will start back up and do the same thing.

Why is there no oil pressure in my engine?
We determined it was the engine oil pressure pump not getting enough flow to the high pressure oil pump that feeds the HEUI (hydraulically actuated electronic unit injector) system. The oil pump is crank driven and has a direct passage to the high pressure oil pump reservoir.
Why does my DT466 start harder cold than hot?
To answer your voltage question, that’s EXACTLY what is likely causing your problem. On a cold engine it takes more battery power to crank the engine compared to a HOT engine, so it starts harder cold – we all know that.
