Valve lift is the distance that the intake and exhaust valves move on the engine. This distance is controlled by the camshafts and it is crucial to the engine’s performance. Valve lift sometimes goes by gross lift but the terms are interchangeable. The cam is a lobular shaft that opens and closes the valves as … Read more
A purge valve or canister purge valve as it is sometimes called, is used to control emissions in a vehicle. Its part of the Evaporative Emission Control (EVAP) system.

Performance engines produce a lot of heat. In fact engines can produce so much heat that it vaporizes oil. Oil vapors are not good for the engine because these vapors can cause build up on the engine components like the valves and the vapors can lead to an increased oil consumption. Increased oil consumption it … Read more
In a turbocharged engine, the level of boost is controlled to a set psi. Boost creep is what happens when that predetermined level is exceeded. In most cases, this problem is caused by a fully opened wastegate not being able to bypass enough exhaust gases creating extra boost that exceeds the set level. Boost creep … Read more
