Turbos Smoking? Weak Boost?

If you can't remember the last time you replaced your PCV, It's been too long!

Why It's So Important:

The intake manifold is under pressure during most running conditions when an engine is turbocharged. The gas and oil bypassing the rings are still present, and the pressure generated by the turbocharger can increase crankcase pressures. That’s when a more advanced PCV system is required.

Vacuum is present before the turbocharger. On some engines, the vacuum is greater than the vacuum generated by the pistons moving downward, but not all the time. Vacuum is generated only when the turbo is spinning. Typically, the area before the turbocharger is where the vapors from the crankcase are fed into the engine. Some turbocharged engines will feed crankcase vapors to the intake manifold with a bypass valve when the turbo is not creating enough vacuum.

Turbochargers do not like ingesting the oil that can be found in crankcase vapors. The oil can form carbon deposits on the vanes and housing and cause a loss of boost.

Clogged PCV systems can even contribute to overboosting via excessive thrust = Dead Turbskis
