Can somebody tell me how to route the oil tube from the oil fill neck when using a single turbo setup, Should I use the check valve and in what direction?

 

If you talking about the purge control or the charcol cannister most guys with singles get rid of those to clean up the engien bay.

 

Sorry my car is an FD and the canister is near the fuel tank

 

The oil tube does not come from the oil feed neck . the oil feed tube to the turbo is the banjo bolt and line infront of the oil filler . Go look for your self . The line from the oil filler neck that runs with the oilline is a vacuum line from the turbo air intake.

 

Ok thats my point what do I do with that line (vacuum line) that use to go to the turbo inlet pipe, now that I have a single turbo.

Where do I put that line? I cant plug it
