Morning all,
I'm needing to know is this one way valve needed that goes onto the inlet manifold?

In the picture is the way valve that goes between a black vacuum pipe and inlet manifold. With going rotated I don't use the vac take off that goes from the one way valve to the turbo inlet.
Can i do away with this one way valve or is it needed for running or stable idle etc?
Or basically what is its job?.
Many thanks for your help
Chris

 

Im also needing to know this.

What are you doing about oil drain tube mate, i was going to use silicone hose but been advised not to and dont fancy giving a hundred quid for the rcm one

 

For the oil drain I just used some black braided oil grade 16mm piping and 2 jubilee clips.
Pipe from any motor factors or hydraulic company
It's used on oil hydraulic lines so more than man enough for a drain.
Cheers
