The crankcase ventilation system is essentially maintenance free. There are no mechanical components that need to be adjusted, nor are there any parts that need to be replaced on a scheduled basis.
The only checks that can be made to the system is for plugged or cracked hoses and faulty connections.
- Remove the hoses from the connections and check for restrictions. If restricted or damaged, replace the valve
- Inspect the hoses for cracking and replace as necessary.
- Install in reverse order of removal making sure that the hoses are fully seated.
