Direct injection means no fuel washes over the valves. By 50,000–60,000 miles, the intake valves look like charcoal briquettes. ep6dt engine problems
If left untreated, the chain can skip teeth, causing the engine to lose timing, enter "limp mode," or suffer catastrophic internal failure. 2. Carbon Buildup on Intake Valves Because the EP6DT uses Direct Injection (DI) Before buying any EP6DT-equipped car (Mini Cooper S
