Hi
I have just purchased a 90% complete series 1 and I have a question relating to the inlet manifold vacuum pipes. On the top of the manifold there are 2 take offs, where do these go? I have 1 going to the ecu but the other is left open.

Thanks
Phil

 

left elbow to the black plastic breather valve that connects to back of rocker cover (timing belt end)

 

Thanks mate. I thought it may go there. I'm guessing it has a non return valve on it.

 

me s2 has non return valve

 

Series 1 cars did not have a non return valve IIRC. If going beyond stock boost it is probably a good idea to fit one .
