On the inlet side of the XE block there seems to be 2 breather pipes - one breathes into the throttle body and the engine eats all the nasty fumes.
Why, in particular, is the other one there. It seems to breathe back down the inlet tract - what is the point of that?
I notice Oddball said in a thread that he had blocked off this one with a bolt in the breather pipes.
Does that mean all the fumes just go down the remaining breather? Just wondered as I've never had the cam cover off.
Any info much appreciated
