I have an escort cosworth and I have recently rebuilt it and changed to a 2wd exhaust manifold, I'm having a bit a trouble lineing everything up, I have had the turbo reconfigured for the manifold and I was wondering if I had to change the oil rutirn pipe on the turbo to a 2wd return pipe. Cheers

 

please help, someone must know if I need to change the return pipe! Please please
