On a 1986 Chevy 305 engine, the Positive Crankcase Ventilation (PCV) valve is typically located on the valve cover. It is usually found on the driver's side valve cover, fitting into a grommet. The valve connects to the intake manifold via a hose, allowing for the circulation of gases from the crankcase to the intake for combustion.
