I was pokin around under the hood yesterday and noticed that my engine has a 24V valve cover on the top.

Is a 24V a common rail, or did someone switch my engine on me in the truck? :/

 

All common rail Cummins are 24 valve, but not all 24-valve are high pressure common rail. Yours is both. The 2nd gen 24-valve engines aren't.

 

Forgot to thank you for the answer, thus, Thank you.

 

sorry bout the newb question, not new to the forum, just the diesel nitty grittys,

what is a high pressure common rail. i have a 2nd gen 24v so appartently i dont have it, just interested to know what it is that i do not have. thanks

 

Your truck has a VP44 fuel injection pump, which runs at a low pressure. The HPCR uses a CP3 fuel injection pump, which pushes fuel to the injectors up to about 30,000 psi.

 

right on, preciate it. sorry bout the thread jacking.
