Is is normal to have so much play where the Brake Servo hose enters the intake manifold , see attached video? I am getting the notorious P1171 and P1174,codes. Replaced the MAF with a Denso, new K&N air filter, and I am suspecting a vacuum leak as the culprit? Is that connection into the intake manifold supposed to be completed sealed, or some play is normal? This is on a 2003 Disco II, Thank you so much for all your advice.
