Thanks for the link. When I follow the vacuum lines from these two valves they have black return lines that tee into the VCV which also tees into a black line that goes through the firewall (vent ?). Can I just connect the line that goes/comes through the firewall directly into the VCV. Looking through the threads mentions that these vacuum valves are on top of the valve cover. Mine are not. They are on the passenger side fender wall. I also don't have a vacuum line going to the thermostat and then then the EGR. just some more info. Thanks
