PCV System

Recommended Posts

2019 Silverado 6.2L. This is my first DI engine. Been reading about the dirty intake valves and a catch can. Looking at the engine, I only see 2 short lines in total for the PCV system. Front driver side valve cover goes to top of throttle body. Passenger side front valve cover goes to air intake. Am I missing something? Is there another line somewhere? Is the PCV valve in the valve cover? I would assume on the driver side?

unless your running a supercharger, theres no point in filtering out the valvecover port to the intake. 80% of the oil consumption is thru the manifold to pcv port

i have a 2016 truck, yours is on the drivers side manifold ,and runs down to the engine valley area, near the water pump, uses quick release  fittings. it looks like a 3/8" pvc tube. you can make your own catch can just search.  try pulling the engine cover off  , the manifold has a pcv check valve connected to the pcv line.

Checked installation instructions for a catch can on the 2019+ 6.2 and there is nothing under the engine cover. What I have pictured is it. I see some people talk out the side of their neck.

Look at the upr catch can installation instructions. The PCV valve is in the driver side valve cover. Nothing under engine cover. Nothing in the valleys. 2019+ 6.2 must be different than yours and you assumed it was the same.
