444 cummins?

I dont know about your first question, but the second one is yes they are low flow. I have heard of guys switching them over to high flow, but I had a 87 star with a 444 cummins in it, and I never had an issue with the truck overheating, not once.

I was skeptical when I bought the truck, because of all the bad that I have heard about these engines, but mine was really good, had lots of power, reliable, good on fuel.

Curious to hear what others say about them.

 

Most problems with the low flow engines is the radiator blocking plates are broken.
The 444 has step timing controls using oil to advance the injection timing. I use to do most of the work on them at my work, they are very suseptable to oil leaks from a lot of different places, and just because you change an injector with a new one does not mean it will not leak. Working on them you may have to take it apart 2 or three time to repair all the leaks. They have very little torque at low RPM to start. We had one in a fire truck with an automatic, it would not start on a hill, they had to replace it with a Detroit.
If you have a choice I would not buy it.
Just a thought

 

I did not say all Cummins did not pull at low RPM just the 444, they would pull down from higher RPM to 1200 but had nothing coming up. I would rather have an M11 than a 444 any day.
Just a thought!

 

I love my m11, good engine and love those 7mpgs, had an 89 frt liner with 444 in it had problems with it so finally it was replaced with a 350 cummins
