popping from vacuum pump

1 post in this topic

my 2004 v70 D5 has got the popping noise when you remove the oil cap ,tested the vacuum system and found the front engine mount was leaking this has now been replaced but the popping noise remains, strange thing is if i block the outlet from the the vacuum pump the popping noise remains the same, i've tested the vacuum pump with a gauge and it holds good vacuum and the brakes also work very well so i'm a bit puzzled as to why i still get the noise.

this video is with a vacuum gauge straight from the pump outlet.
