Timing chain failure is a prevalent issue in the GM Ecotec engine, often accompanied by characteristic signs of deterioration. The screens of the variable valve timing solenoid become contaminated with metal particles, prompting the illumination of the check engine light. To prevent additional damage and potential cylinder head and valve problems, it is crucial to maintain the engine's oil levels and follow the recommended oil change schedule. The timing chains, guides, and tensioners should be replaced at 100,000 miles. Call us today to schedule your appointment 636-757-3990!
