Heard allot about changing the Pcv so wondering where it is and how I will know if it needs changing???
The search function is your friend.
Circular plastic thing on top of engine which releases blow-by boost pressure from the crank case into the inlet. If you car is running fine then don't worry.
You may want to replace the cam follower though if you've got 60+k miles.
- again, search will help you out
