I have been rebuilding a 2001 Camaro Z28 SS LS1 engine with a blown head gasket. I acquired the car with the intake already removed so I could not see what was connected where. I am now ready to install the intake. On the back of the intake is a bunch of vacuum connectors. In particular, there is a small 1/8" diameter Tee. There is one line that fits that and it seems to go to the EGR system. I cannot find another 1/8" line that connects to the Tee. I have the other larger lines figured out. I have a 98 LS1 but it is a bit different. Does anyone know what the other 1/8" vacuum connection go to?
Thanks,
Ted
