I recently had injectors replaced, injector harness and injector cups replaced. increased power ran good for only 3 days. lost tremdous amount power, low oil pressure, checked oil level, needed 2gal. ran good for 3miles and gave out. checked oil level did not mark on the dipstick. checked fuel filter,diesel very dark. replaced fuel filter, no change. checked fuel tank seems motor oil is in the fuel tank. any suggestions?

If your talking about the truck in your signature then it's a powerstroke and not an IDI. Hopefully the mods will move it to the right forum. Sounds to me like the seals at the injectors are leaking.

You need to contact the moderators, cause the engine is a powerstroke. You'll have a much bigger audience and a better chance at the correct diagnosis.

The T444E uses high-pressure engine oil to build the necessary pressure to inject the fuel. If that oil is leaking inside the injector pump you'd see a loss of power because the necessary pressure isn't building up. Plus, the leaking oil could mix with return fuel and end up in the tank.

You also could have injector O-rings failed (with the low miles if this is the problem it is bad installation).

T444E's do not have an injector pump. They do have a HPOP. A leak in a HPOP can not mix with fuel. Pretty much the only way oil can get into the fuel is a bad injector o ring.
If you had the injectors replaced at a repair shop, they should go good for them.
Sorry about the bad advice to the OP, we had the same thing happen to one of our fuel trucks at work (T444E 4700) and when I asked was told that's what had happened (I didn't work on it for that problem but was curious in case it ever happened again.)
