I'm not sure but I really would avoid putting into the front crank breather separator pcv. On boost that pressurises and will try to force oil/vapour back through the turbo if the vent part is blocked.
You also need to take the crank breather back BEFORE the turbo not after. On the fiesta zetec the return is to a sandwich plate between throttle and head, on boost that will pressurise and cause all sort of interesting issues (such as blowing all the oil out of the rocker breather!). On mine I have blanked the sandwich plate off. The front crank breather system is standard but connected to a stub pipe welded to the side of the inlet tubing directly after the air filter. My rocker cover is piped to an oil separator then air, however I will connect that to the air filter and t the crank breather in a quite a bit of oil 'crud' still gets through the pcv. If none of that makes sense I can draw you a small diagram. M On 7 Feb 2012, at 22:18, nigelp <[email protected]> wrote: > Thanks guys.
