This pin can back out of its hole and fall into the timing gear, with catastrophic results for the rest of the engine.
Fixes are available, and any buyer of one of these trucks should check this work has been done. Another thing to pay special attention to when you are looking at Dodge Cummins trucks is to make sure you see the truck start from cold since a worn-out diesel engine will often struggle to cold-start.
This is a good reason to arrive early when you go and see a used truck, as you might catch the seller trying to warm it up to hide the issue. Under the hood, you can expect some oil residue and dirt on higher mileage vehicles, and you can use this to check for oil leaks from the block.
Inspect the block closely, looking for any clean streaks , since that will show you if any oil has been leaking recently.
Check compression is still strong by testing for blow-by. This is done by removing the oil filler cap and while the engine is running, and looking for smoke coming from the oil filler hole. An all-new body style of Ram was launched in , and this design probably began the current trend for huge, aggressive-looking pickups.
Featuring a raised hood line and low fenders, the Ram looked similar to an eighteen-wheeler semi-truck and sold very well. The valve Cummins model remained a key offering, available in the larger and models. For , the Cummins made hp and lb. Between and , this increased to hp and lb. Dodge introduced a new version of the Cummins-powered Ram in This was done to reduce emissions. The other main difference was the 24 valve cylinder head. Manual transmission trucks made hp and lb. For and , two versions of the engine were offered, one with hp and lb.
The High Output version had a higher compression ratio The fuel system was developed to flow more fuel. It was only available with the new NV six-speed manual transmission. The changes included the introduction of the four-door Quad Cab, which used small clamshell doors directly behind the main doors, making Ram the first extended cab pickup to have four doors. Other changes for included a revised interior and dual airbags. Brakes were upgraded to dual-piston calipers at the front, and heated seats were an option on model year Rams.
The VP44 is not as reliable as the P Many Cummins enthusiasts recommend fitting aftermarket fuel pumps , perhaps an Airdog or a Fass. Some Cummins-engined Rams from the and model years suffered from a casting defect that reportedly caused the engine block to fracture.
Dodge replaced a large number of these engines under warranty. Additionally, the 24 valve cylinder head has proved less durable than the earlier valve, experiencing valve seats cracking at higher mileages. The redesign of the Ram included a new frame, suspension, interiors, and sheet metal. Styling was by Cliff Wilkins and was very much derived from the previous generation.
Rear-wheel drive and models had rack and pinion steering and independent front suspension. The new models were well received, and and saw record Ram sales of , The 12 valve and 24 valve Cummins Rams share the same bore and stroke, and the same Holset turbo. The new Cummins for now featured common rail injection and made hp and lb.
During the model year, the High Output Cummins was introduced, making hp and lb. A marine version of the 24 valve was also offered, designated the QSB. On the transmission side, the 47RE automatic was upgraded internally to increase durability and torque capacity and was renamed the 48RE. It remained four-speed. When looking at a 24 valve Cummins Ram, there are a few simple tests you can do to identify typical issues. See if you can have someone else start the truck so that you can be at the tailpipe.
Is there blue smoke? If so, that is oil, and it is very likely an injector or injector pump issue. While you are at the tailpipe, sniff the exhaust fumes. Can you smell anti-freeze? If so, the truck may have a head gasket problem.
With the truck running, the idle should be smooth, and not pulsing. Gently rev the motor, up to about rpm, and then allow it to fall back to idle. The revs should rise and fall should smoothly. Any unevenness suggests a problem with the injectors or injector pump. These later engines lack the enormous performance potential of a properly tuned 12 valve, but it is far easier to extract a limited amount of additional performance from the 24 valve engines. Simply attaching an electronic tuner and remapping the fuel injection computer can yield significant power, torque, and gas mileage improvements.
In , the Ram had a mid-cycle facelift, which featured a tidied front end and updated headlights. For , a new 6. Both bore and stroke were increased to give the extra displacement.
It produced hp and lb. AAM axles replaced the Danas of previous generations. The 6. This reduces turbo lag by means of sliding vanes in the exhaust which create optimum back pressure. As mentioned above, most people buy diesel trucks for their superior torque output. However, horsepower is also important for towing and hauling. It enables the truck to get up to speed faster. Towing capacity is based on more than just the engine. It also depends on the structural design of the truck.
Different models and different trims within a particular model might tow more or less, depending on their equipment. Some trims come with towing packages that increase the towing capacity of a particular truck. In general, the maximum towing capacity in any truck will be found on a 2WD trim.
A 4WD truck will always have less towing capacity vs. It also covers the majority of popular towing items, such as campers and boats. However, diesel engines offer more power than gas engines and generally superior fuel economy. The most recent model of the F 3. The most recent model of the Titan XD 5.
Most diesel enthusiasts seem to agree that the Cummins Turbo Diesel is the better engine in terms of reliability, but the Ford pickups tend to last longer and be more reliable than the Ram pickups. The top problems on these two engines are as follows:. The exhaust manifold issue with shrinking and cracking is most often found on trucks with the CTD that do a lot of towing. The Powerstroke Diesel turbocharger issue happens mainly to tuned engines as the additional horsepower and torque cause the ball bearings of the turbo to degrade.
For light-duty trucks with a PSD or CTD, the best warranty you can find is , miles or five years on the powertrain. Ford, Ram and Nissan all have this warranty on their diesel pickups.
Medium-duty Ford diesel pickups come with a ,mile warranty. The CTD is arguably the most popular diesel engine, and it has the most name recognition. Buyers looking for their first diesel pickup might lean towards the CTD for this reason alone. In terms of the trucks themselves, the Ram is also a popular truck. However, Ford trucks in both diesel and gas forms have long been among the best-selling vehicles in America for many years.
This is especially true of the F Verdict: Another tie. It features responsive performance and low noise, vibration, and harshness while driving. Mileage should not be your main concern when it comes to these 6. Many owners will admit to purchasing clean, reliable, high mileage Rams without major issues. Obviously, if you can afford a lower mileage truck, then why not, however, any vehicle will eventually need expensive repairs, including things like front end suspension work.
I daily drive an 6. Well it is a Currently have k. The 68rfe did give up on me about k but I was not so easy on it for a few years right after I deleted it. Once deleted. All modern diesel trucks are equipped with devices and components to make them friendlier for the environment and minimize the impact of pollution as much as possible. There is no concrete evidence to support the theory that a deleted truck lasts longer. Many will have you believe that a Cummins 6. You can expect the DPF to start giving issues around that point once it starts to not regenerate.
The regeneration process is necessary to reduce the accumulation of soot build-up on the DPF walls. Once this fails to happen, your will get engine error codes and limp mode issues to protect the engine.
Owners have reported DPF failures from around k miles and opted for a delete. Many trucks then continued on to well over , trouble-free miles thereafter.
Cummins has an exclusive membership for owners with Cummins racking up over miles or more. After which it needs replacement. You might get away with higher, depending on the kind of driving the truck was exposed to. I put that on in about 11 months.
