wild bill Posted January 14, 2019 Share Posted January 14, 2019 I'm so close to finishing i can almost smell the burning rubber. Halfway down my 2.3 duratec block to the rear on the LHS just before the gearbox bell housing is a rubber half inch hose coming out of a black plastic housing which goes nowhere. I don't ever remember seeing it or disconnecting it and its not going anywhere and there's no circlip marks to indicate that it ever did. A sneaky suspicion says its a crank breather but that's just a thick guess from an idiot.Anybody got any ideas? Link to comment Share on other sites More sharing options...
sjl1 Posted January 14, 2019 Share Posted January 14, 2019 Think that is the crankcase breather, mine goes to the plenum but am planning to move it to the oil catch tank, (other breather comes from cam cover) having recently found overfilling sump leads to smoke from exhaust when oil breather sends oil to plenum Link to comment Share on other sites More sharing options...
