Intake Manifold

My son has an 03 Ram 2500 quad cab sb 4x4 5.7 hemi. Looking to replace the intake manifold, we can only find 04 manifolds. What is the difference between the 2 years?

03 manifolds don't have EGR. 04-08 1500 manifolds have EGR, but the same year 2500/3500 manifolds do not. Look to see if the EGR hole is punched out or not.

I just bought a 2016 Sport a few months ago with 85,000 miles on it and decided to change the oil on it. While underneath it I noticed things mostly on the passenger side with a film of oil just enough to collect dust. I followed the film up and it was coming down the back of the passenger head. Thought it was the valve cover so I decided to check the bolts on it. Not one was loose. Decided to check the intake bolts and all 10 of them were loose. I couldn't turn them with my fingers but putting a torque wrench on them I turned them all near 2 complete turns before they torqued down to 105 inch pounds. Time will tell but I'm hoping that was my leak. It has every reason to be. Doesn't hurt to check them, easy to do in about 10 minutes. 1/4 inch torque wrench, 4 to 6 inch extension and a 5/16 socket. Sorry if there is already a new thread on this, the one I found said it was an older thread and I should consider starting a new one.

This is a common thing, these bolts need to be retightened on a regular basis.
It’s a good idea to check when changing your oil.
