PASSENGER SIDE MANIFOLD

1997 Chevrolet Camaro • 10,000 miles

Picked up salvaged "stock" passenger side manifold for Z28 in the back near the 02 sensor is a threaded bolt hole and above it is another hole with no threads. What goes into these?
thanks,
weekend mechanic

It could be air injection tubes, the EGR valve pipe. Or, If it is part of the heat shield, not sure if it has one, the dipstick goes through the manifold.


Thanks, I am sending a pic so maybe you get a better idea. Bottom right near the studs.

A tube from the vacuem pump goes their. If you dont have this you got the wrong part.
