The most frequent problem of 392 Hemi engine per owner’s report,

The Hema engine line presented by Chrisler is widely responsible for the popularity of the “Hemi” engine. However, this technique was originally originally worked on by a Belgian company called Pipe in 1909. Chrisler used the design for V12 and V16 tanks and warplane engines in the World War II, and began in 1951, it started. Place the Hemi V8 engine in its vehicles. In the piston, the combination of combustion chambers, which suit energy transmission and allow the installation of huge valves, gives the engine its name. Hemis was closed in 195 88 and 964.64, while the model was a 66 cubic inch version of the model that created 425 horsepower in the second generation (source: motor trend).

With the displacement of 392 cubic inch (6.4 liters), the most recent repetition of the third-generation Hemi was originally mounted in the 2011 Dodge Challengers and the Charger SRT 8 muscle cars. The Jeep Grand Cheroki and Dodge Durango SRT SUVs were identified as this option. Nowadays, Chrisler 300, many RAM truck models and jeep cinger Rubicon 492 all use it. Although 392 only refers to the new look package, the challenge and the charger SRT8 have been named Challenge and Charger SRT8 392. Based on the official Dodge data, 392 hemies of the Charger SRT Jail’s Super charge created 807 horsepower and 707 LB-foot feet. Tork.

Some 392 Hemi Owners Have Filed A Lawsuit

However, there are some good research issues with that performance. According to the help of Limbu Act, Hemi Vehicle owners have launched a class-action process case, alleging that the 392 cubic inch V8 engine has a multi-display system (or MDS) design defect. This device varies between four-cylinders and eight-cylinder operations in response to the engine demand. When the engine starts, the error creates a hearing ticking sound. In addition, the metal pieces in the broken valves can enter the engine and damage the internal engine as well as damage the walls and camshafts of the cylinder.

According to the lawsuit, Crisler violated the car’s guarantee, regardless of replacing the damaged engine parts or misconduct thieves. To replace the 392 hemy engine, the car owner will have to pay about $ 15,000 from the pocket and the same problem can occur frequently in the replacement engine. Fiat Crisler’s dealership Service Department received a notice of technical service known as Star Report in January 1, which states that “consumer complaints may include unusual engine noise, rough passive, lack of power, [and] incorrect.” The technicians were asked to remove the oil control valve from the variable valve timing system and inspect the cam lobe for damage or metal pieces. If the breakdown is discovered, the engine should be replaced.

Exhaust Manifold Studs Can Also Break

Since 2005, different Hemi engine has been equipped with MDS; However, this manual gearboxes, with the initial hem-power RAM 2500 and 3500 pickups or 6.1 LSRT or 6.2L helkat are not compatible with high-performance. According to Tuning Pro, there are three primary areas of failure in the MDS system: defective solenoids, unclean oils that allow the lifter rollers to come in contact with the camshaft lobe and release the valve seat as a result of low temperatures of cylinders.

The Hemi owner passing through the Monicar Zillar describes the Lifter’s problem in the post at Hillcat. Org Online Forum. He mentioned, “The thieves can suffer bad oil.” Therefore, the engine can easily operate the thieves by lubricating the low RPMS. Roller when Cam lobes hit by nail thieves may not roll over the lobe, but instead smack it.”

The Motorover asked Hemis owners to use 0 W -40 oils and regularly replaced it, the lifter was identified as an innocent valve sound. In addition, the website identified the design flaws in the exhaust manifold, which can cause heat-inspired bends and mounting studs.

The 392 Hemi’s Pistons Are A Weak Point

392 Hemi’s owner, Matt Jude, expressed his disappointment at the Cummins Forum and described the problem of handling your engine and dealership. “I have the same problem with 2 motors now and they blamed oil changes.”

Additional issues with 392 cubic inch Hemi were described in a video posted on the Marspid YouTube channel. The performance of the forced-air induction system and the outmarket superchargers is very high for lightweight pistons and they can damage engine cylinders or valves. This is because excessive ring gaps and piston crown for the sake of the upper piston ring land. In addition, lifter bearings may fail, and lifters can stick to the cam until the valve is no longer functional open or close properly. This can cause misfiring on the affected cylinders.
