Peruvian Mechanics Solve Two-Year-Old Car Mystery Using High-Tech Tools

In a small automotive repair shop in Peru, a team of mechanics recently solved a complex problem that had baffled other professionals. The subject was a Great Wall C30, which had suffered a significant loss of power for over two years. Despite multiple attempts to fix the issue, including spark plug and ignition coil changes, the problem remained. "We used an oscilloscope," explains Clinica Automotriz Oficial's lead mechanic, "because sporadic faults don't always show up on a standard scanner." The oscilloscope revealed misadjusted valves in the intake and exhaust. The root cause, according to the mechanic, was the use of low-quality oil or infrequent oil changes. "The engine wasn't breathing properly," he stated. The solution involved replacing the variable valve timing system and the OCV valve. The case highlights the importance of using proper oil and timely maintenance to prevent costly repairs. This successful diagnosis serves as a reminder of the value of precision tools and expert knowledge in automotive repair.
