5 Clean the crankcase ventilation filter cover with warm soapy
water.
6 Dry with compressed air.
7 Examine the cover for cracks. Replace the cover if damage is
found.

Install
1 If the gasket was removed, install the gasket into the rocker
lever cover groove, starting with the tab end first. Then install
the corners opposite the gasket tab end. Finish by pushing in
the sides (see illustration).
2 Gently push the gasket down into the groove. Do not use a
finger to trace the gasket around into the groove during instal‐
lation, as this will stretch the gasket, making it difficult to fully
seat into the groove.
3 Do not cut the gasket to make it fit into the groove, as this will
result in an oil leak.
The gasket must be fully seated around the entire perimeter
of the rocker lever cover groove.
4 Apply clean 15W-40 engine oil to the o-rings on the crankcase
ventilation filter.
5 Install the filter onto the rocker lever cover.
