5.9 Liter V8 Dodge Engine Reviews; the common problems.

5.9 Magnum Plenum Gasket Leak.

On the 5.9 Magnum, the intake manifold, also known as the intake plenum, comprises two sections. The cast aluminum manifold at the top and the pressed steel plate at the bottom make up the plenum. A plenum gasket joins the top and bottom parts.

Gaskets on any engine are notorious for deterioration and wear. The plenum gasket regularly fails on the Dodge 5.9 Magnum. When the gasket breaks, an air leak will occur, causing the engine to lose vacuum pressure, which can cause a variety of problems.

A damaged plenum gasket may be identified using several methods, but most people don’t know they have a problem until their catalytic converter is blocked. You’ll notice a significant drop in power when the cat is clogged. As a result of an inability to effectively expel air from the engine due to clogged catalytic converters, engine pressure rises, further increasing the risk of cylinder heads splitting.

Cylinder Head Cracks – Dodge 5.9.

The 5.9 Magnum’s cylinder heads are its most significant flaw. A new design featuring higher airflow and bigger valve sizes and an enhanced combustion chamber structure has made the heads of the LA 360 engine much more vulnerable.

High temperatures are the most typical culprit in damaged cylinder heads. Excessive engine heat can be caused by various factors, including coolant leaks and failures, including those listed above. The cast-iron cylinder heads expand and break apart due to a rise in engine temperature. Because the valve seats are induction hardened into the heads rather than pushed in, they are more prone to cracking.

It’s nice to know that while some shops estimate that 50% of 5.9 heads have fractures, most of the flaws are little. Despite our warnings, people have been known to drive for years with cracked skulls without experiencing any severe problems.

The new 2021 Dodge Durango srt Hellcat is a remarkably powerful SUV. While its price tag and performance are both highly impressive, its interior has some serious concerns. For those interested in this vehicle, here are some important facts you should know. – itismycar.com

A problem with the timing chain.

When discuss about the 5.9 Liter V8 Dodge Engine Reviews, we can’t forget about this matter. The valves are opened and closed by the camshaft and crankshaft, respectively, which are linked by timing chains. Engine air and gas can be drawn in through the intake valves, but the exhaust valve stays closed. The exhaust valve opens and pushes the exhaust out whenever the intake valve is closed. Timing chains manage each cylinder’s and valve’s timing in the same way.

It’s normal for the timing chain on the 5.9 Magnum to stretch with time, as is the case with other timing chain engines. While a lack of frequent oil changes might aggravate this problem, the timing chain on the 5.9 Magnum typically starts to strain around the 100,000-mile mark. I would consider replacing the chain at the 150,000-mile mark if it hasn’t shown any wear or stretching before that point.

There is a weak front end in the 5.9 Magnum.

At 5.9L, the Magnum 360 is a massive engine and hence has some actual weight. Unfortunately, the front ends, notably on the Dodge Ram‘s that the 5.9 is in, are a weak truck area.

While these faults aren’t directly engine-related, I felt it was worth highlighting that additional maintenance could be necessary for these trucks. Obviously, as with everything ancient, components need to be changed.

As a result, the Dodge Ram’s front-end parts have a weak reputation and need to be replaced as the vehicle ages. To avoid surprises, be aware that some of these parts may begin to fail earlier than expected in high-mileage vehicles.

5.9 Magnum Transmission Problems.

Although not an engine issue again, a common concern that bears highlighting is the gearbox dependability. Overall, the 46RH and 46RE transmission utilized with the 5.9 is quite a shotty at best.

Additionally, the torque converter and transmission cooling lines have been known to fail. Reverse and overdrive assemblies frequently fail on 44 transmissions as well. Tow-haulers, especially those who use overdrive, will run into problems far more regularly than those who don’t tow and drive cautiously.

A fully repaired engine with updated internal parts is rock solid. Seals, for example, have deteriorated and worn down considerably since they were new in these over 20-year-old trucks. Keep that in mind. If you’re driving a vehicle with a transmission that hasn’t been rebuilt for more than 150,000 miles, it’s likely to be inoperable.
