Re: Valve Covers - help pls
Hi Bill and welcome to AF.
The open holes in each valve cover are for the PCV (positive crankcase ventilation) system, or, some folks just run filtered "breathers". The one with the cap is for adding oil to the motor.
The PCV system is the best for the environment (emissions) and less fumes into the cockpit.
Leaving these holes open, as they are, introduces dirt particles into the engine and is not a good thing.
Do an internet search for PCV systems to see how they are hooked up and work.
Also, after market valve covers just come with one breather hole in each.
