A wastegate is a valve that controls the flow of exhaust gases in a turbocharged engine. It is designed to open when the boost pressure reaches a certain level, allowing some of the exhaust gases to bypass the turbine wheel. This helps to prevent the engine from overboosting and causing damage.
There are a few different ways to check a wastegate. One way is to use a boost gauge. A boost gauge will measure the pressure of the boost coming from the turbocharger. If the boost pressure is too high, it may indicate that the wastegate is not opening properly.
