I recently bought a really nice 1999 Dodge 24v Cummins Turbo Diesel 4X4, and as it is my first diesel rig I am obsessing over learning everything I can about them. I was wondering if any NWFA members have a 12 or 24v from these years, and what they may think about them.
I called Cummins on my engine block as there were supposedly some with casting defects called "#53 blocks" during these years (98-01). Cummins ran my engine serial number and verified that mine was not from the facility or the years that these problems occurred. They also said the percentage of failures was tiny (Approx. 2% or less than were manufactured) compared to the number that run with never having an issue. I also asked about what is known as "KDP" or killer dowel pin, which is an alignment pin on the front of the engine (behind timing cover) used during assembly that can work its way free and fall into gears causing major engine failure. While the problem is more common in 12v engines, the early 24v also had this pin. My truck apparently has an updated cover and pin that does not have this issue, so another bullet "Dodged"! I have also installed a fuel pressure gauge to monitor the lift pumps pressure into the injector pump, as this was another common part failure on these engines. Luckily, my pressure is within good operating range, so no expensive parts bill for me!
I lucked out finding a truck with low miles (140,000), and has a brand new auto tranny still under warranty with top of the line upgrades, plus alot of other newly replaced stuff. Apparently these rigs are in a high demand right now, as I found during my search. I bought from an elderly couple, but all of the many dealerships I went to said they had a huge waiting list (some were 20-50 people long!)for this type of rig, and would sell them before they ever even showed up on the lot. Pretty amazing.
So, anybody own one of these or have a story about them? Thanks!
