hello all new here...... we got a 2015 LR4 a couple of months ago which is now showing an a/f leak.... I pulled the top cover and ductwork bits and pressure tested to 15 psi...saw some a/f running out behind the crank pulley.. checked with a mirror and couldnt find where it was coming out of the waterpump but if i looked by the throttle body under the super charger i could see a/f ugh.....thanks all in advance
