Importance of Routine Oil Changes Highlighted in Dodge SRT8 Hemi Engine Teardown Video

Early Dodge Charger and Chrysler 300C Models Used this Engine

The Hemi V8 is a high-powered engine that can experience issues if not properly maintained. This 6.1-liter Hemi, set to be disassembled, seemed to have fallen victim to neglect.

Eric, the owner of I Do Cars, was uncertain about the origin of the defective engine. This specific Hemi V8 was available in SRT8 versions of the Dodge Charger and Chrysler 300C during the 2000s, but both models were discontinued just last year. In its prime, the engine boasted an impressive output of 425 horsepower and 420 lb-ft of torque.

Prior to the dismantling process, Eric observed heat indicators on the motor, which are utilized to assess if the engine was subjected to excessive heat. The tabs appeared undamaged, implying that the malfunction of the engine was not caused by a failure in the cooling system.

The components beneath the valve covers appeared tidy, though some signs of wear were evident. Nonetheless, traces of tiny metal fragments were present in the oil, indicating potential engine oil deficiency and possible damage to one or more moving parts.

The removal of the cylinder head from one of the banks resulted in the leakage of coolants, which was not a positive indication. This caused the accumulation of moisture on certain components. Fortunately, no fractures or deformations were discovered during the inspection.

Upon closer inspection, it was discovered that one of the roller lifters had sustained serious damage, which accounted for the pristine condition of one piston head. This indicates that there may have been issues with engine misfiring, as the valve was unable to open properly and resulted in the accumulation of fuel in the cylinder. As a result, the fuel acted as a cleaner, leaving the piston head spotless. Eric further observed considerable harm on the camshaft upon examination.

In the meantime, there were some pieces of metallic debris present on the oil pan, although it was deemed to be in relatively decent condition. However, upon inspecting the components in the timing assembly, Eric noticed signs of wear on a few of the primary connecting rod bearings and the walls of the cylinders.

Hemi engines and Chevy’s LS power units are known for experiencing issues with lifter failures, particularly if the vehicle has been left sitting idle for prolonged periods of time due to poor oil servicing. It goes without saying, regular maintenance is more cost-effective than having to replace an entire engine, so it’s important to adhere to scheduled oil change intervals. Fortunately, this problem will not be a concern in upcoming Dodge models as they are moving away from the Hemi V8 in favor of electrification.
