its proabbly the EPBV valve on the turbo that is closed. it helps warm the engine up faster by providing low boost from the turbo and keeping the exhaust in the engine longer, warming it up.

it will open up after the truck gets warm. you can either take the valve out or you can take a peice of wire to wire it open. I didnt have one on my truck, so maybe someone can tell you how to do either of these things.

The epbv and the oil is thick. Let it warm up for a little bit. you have a 7.3 right? I let mine run for about 10 to 15 minutes before I drive it. The oil is thick, and it is harder for the injectors to fire. What oil are you running? 15-40 or 5-40. I would run 5-40, if I could find it.

I know the melody of the EBPV and that does not come from him, it does not make cold enough for the moment

Yes my engine is one 7.3 of 2001.
I have just changed my oil for 10-40. I make also the draining of my HPOP with 10-40. Can that come from my gear-box , it misses 1/2 of QT oil?

Mine does the same thing if it is 40 or less and I run 5w40. I really thing the injectors a very tired and need replacing.

I agree. let the truck warm up. When the motor is cold the rings do not seal all the way and the motor is not running the same. The oil is thicker so its harder to squirt it through the injectors. also the timing is advances FAR to help the burn happen since it takes longer to squirt the oil. Ever notice how loud the injectors are when its first started cold? I try to let my EOT get up to at least 80 before I drive off. Then I am real soft on it till 120 EOT.
