    That looks to be a high flow coolant version of motor I guess I am going to try and find the part numbers on the turbo and get on that way I am just trying to keep everything where it all flow together good so that way everything works good together since there are so many interchangeable parts on the motors

    But did you cross the numbers as @OLDSKOOLERnWV suggested?

    To the best of my knowledge all of the big cam 4 Motors were low-flow unless it was converted.

    A crate motor will have a tag on it that says it's a recon.

    I'm not saying that it necessarily is not a new motor, but it's very easy to paint an engine and make it look like new, especially if you swap engines and you really gave it a good shot of paint before you put it in.

    The only way to really know what you have is to do as was suggested.

    A Recon motor will always have a data CPL tag.

    And even if you have that, it does not mean to someone did not rebuild it to a different CPL.

    If they really did change it to a high-flow, they may have made other changes and until you check everything you're not going to know.

    And if you don't know what it is, at least make sure you have a working pyrometer.

    When people start monkeying around with these engines it is very easy blow it up...

    As @Dino soar mentioned, usually a Cummins reman engine will have a tag on it. Usually it is found on the aftercooler and will say “Cummins Recon”.

    The serial number on the block will tell the tail if it truly is a Recon, Cummins will have info on its rebuild.

    And the pictures you shared of your engine @n4ane tells me it is still low flow cooling.

    But as we discussed earlier, if the block serial number, and the pump code number match, then most likely we have a dead ringer, UNLESS someone has been into it....

    My engine is built to CPL 625, but I have oversized injectors in it, as well as a bigger pump and a different turbo..... so we are simply trying to help determine exactly what you have...

    Usually the “Recon” badge will be found in this area.....

    You posted a pic of the part number. If you want to go back with what you have now. B4F30A79-3B2B-47E2-8CF3-3ECF8DFEBD34.png

    How did you get to that? I did find a part number that I put into Google and found one so I ordered it and FedEx delivered it today 20201122_183609.jpg 20201122_183555.jpg 20201119_183402.jpg

    So I used that web site and looked at it and something has been changed on the truck. The intake is different. I was hoping to use that to be able to get the correct part numbers for all gaskets and seals to change the turbo and gaskets on the manifold due to one of the leaking. I guess the gaskets will be ok but the bolts wont be.

    Here's a silly question.

    Did you do what @OLDSKOOLERnWV suggested and check the pump # against the serial # against the turbo # and check to see if you have a data plate with the CPL number on it?

    If you could just do that one simple thing that will take you maybe two or three minutes, we all could help you much better.

    If the tag is covered in paint put some thinner on a rag and wipe it off.
