PCV
The PCV valve is located under the flywheel and allows
the crankcase pressure to escape. The function and test
procedures for the PCV is covered in Chapter 2: Basic
Troubleshooting.
To service the PCV:
1. Remove the flywheel by following the steps described
in the Chapter 7: Ignition System.
2. Remove the two screws that hold the PCV chamber
cover to the engine block using a 10mm wrench. See
Figure 5.9.
3. The cover and gasket can be separated from the
chamber. See Figure 5.10.
NOTE: The dimple in the cover helps locate the fiber disc
over the port that leads into the crankcase.
NOTE: Starting with the 2009 season, a spring was added
to help hold the disc in the closed position. See
Figure 5.11.
