The PCV valve regulates the flow of gases from the crankcase.
Positive crankcase ventilation (PCV) systems have been on just about every vehicle since the late 1960s. The systems route crankcase vapors and droplets into the intake manifold so they are burned in the combustion chamber or catalytic converter.
The PCV valve uses the vacuum from the intake manifold to regulate the flow of gases from the crankcase. The pintle or ball inside the valve moves in response to the pressure difference between the crankcase and the intake manifold. The valve is typically located between the throttle body and cylinder head on a runner for the intake manifold.
There are many combinations for the Volvo modular engine.
Take a look at some of the things you need to know in order to service the brakes on a Mercedes-Benz AMG vehicle.
Incorrect readings can be avoided.
The primary cause of these problems is that fuel and added detergents are not hitting the back of the intake valves.
The system provides great ride & handling, but it can be complicated to service if you do not have the right training.
Technical Service Bulletins can be valuable in helping solve vehicle problems. But sometimes, it takes multiple TSBs to find a pattern failure or the “root cause” of a problem. In the case of the Audi/VW 2.0L Fuel Stratified Injection (FSI) engine introduced in 2006, three problems related to engine carbon and fuel issues are connected
To service them, you will need the appropriate toolset to lock the crank and camshaft.
Unapproved methods will set malfunction codes and, worst-case, you could damage the unit.
