This video in Edd China’s classic car health check video series looks at running checks on a classic car. He checks the exhaust fumes and explains that while pre-1960 classic cars are treated leniently, and classic cars first used before 1975 only require a visual check, vehicles used after 1 August 1975 will require their exhaust gases to be tested electronically. The younger the classic car, the more stringent the test. Edd demonstrates how to look for clouds of smoke and how to check for leaks in the system.
