Hi guys! Ran into a problem identifying the piston on my Dodge. I climbed into the cylinder and took a photo, help me recognize it!? The car has been living in Russia for a long time and only God knows what is now in it. On the forum to ask useless, only show-off and pathos... And there's another question, don't you think the marks on the bottom of the piston are strange?

 

I don't know why I can't upload a photo...

 

Somehow I don't think all the pictures in the world could help me understand this thread......Ben

 

I will try to write more clearly, sorry for my American .

 

I got into the topics of discussion of dodges 3 gen 5.9 ?? right?
My car was built in 2004. according to the documents, High Performance, which means the shape of the combustion chamber under the spray is 124 degrees. the nozzle stands at this angle, but the shape of the combustion chamber is not the same.
I decided to ask you a question, as people from the homeland of my car. Maybe you can help determine from the photo, maybe you can find out what pistons are in the engine. The head has not yet been removed, the photo was taken through the nozzle hole.

 

Who knows the difference between 3 gen Cummins 5.9 pistons??

 

Are you guys kidding? This forum was recommended as a forum that knows about DODGE RAM Cummins! But apparently not... Gentlemen, if I don't ask a question correctly, tell me in a brotherly way how to ask it correctly! I feel a certain language barrier, but maybe I'm doing something else wrong?

 

If I remember correctly, the colored areas on top of your piston are caused by the fuel spray pattern. Your photo would then indicate 10 holes in your injector nozzle. I could be wrong. Maybe someone else would come on and verify or debunk.

There were two models built in 2004. The first one is identified as a 2004 and the other a 2004.5. Take a look at post #3 in this thread for differences in pistons and injectors.
Back to morning brew . . .

 

Thank you for the link. I have already studied the topics related to these pistons and injectors.
The nozzle I have are worth 5 holes 124 degrees. And the piston looks like 143 degrees... ****.. What you can see in the photo is the cutting of the jet. Most likely the engine was repaired and installed the wrong pistons.
Another question is whether there are pistons under a large supercharged up to 5.9 Cummins???
