Looking to install a catch can but have a question. On a 2003 5.3 tahoe motor you have the passenger side hose going into the throttle body from the valve cover and you also have the driver side rear valve cover with pvc that goes into the top of the intake. Which line should i run threw the catch can? Cant both expose oil to the intake???

The passenger side hose goes that runs from the valve cover to the TB is your fresh air source, leave that one alone. You'll want to run the driver side rear hose into the CC, then from there into the intake manifold.
