Is Valve Overlap Bad. valve overlap is the period during the engine’s cycle when both the intake and exhaust valves are open simultaneously. At high rpm overlap contributes to performance by. however, excessive valve overlap can be harmful to the engine, causing issues such as stalling, misfiring, and poor fuel efficiency. in this video (part 1) we look at the basic concept of valve overlap. Not all camshafts have overlap. at low rpm overlap mostly contributes to emissions. overlap is when the intake and exhaust valves are open at the same time. Extreme valve overlap can result in unstable idling and reduced engine smoothness. In certain cases, valve overlap can increase emissions, especially during cold starts or idle conditions. To put it succinctly, it’s when both the intake and exhaust valves are open at the same time. as we said earlier, lobe separation is a contributing factor, but only because it alters the actual source of the familiar chop chop: It is expressed in degrees of crankshaft rotation.
