328adam 0 Report post Posted April 24, 2011 Hey there all.I am half way through replacing the rear cover to my intake manifold.The car began to bellow smoke at start up randomly,so i thought this would be a great place to start. 1.Does anyone know what the plastic pipe running through the inside of the intake manifold- connecting to a plate at the rear does??Mine is just floating around!I have searched and discovered that it should have an O-ring. -I am hoping not to have to remove the throttle body etc. -Do you need this,and could i just get rid of it??? 2.The oil seperator pipe that runs to the back plate also(spring loaded) again was just pissing in the wind.It slides back in,but I donnot know the state of the O-ring and if it will seal etc. Any help or info would be much appreciated.
