hahaha q-tips...bah, did u get your oil changed recently ? if so, it could be that. i had my car's oil changed @ the dealer, and when i got it back, the whistling noise of the turbo was gone, but the boost gauge still showed 6.5 psi. wouldn't you notice how slow your car would be going if your turbo wasn't spooling ? that'd be insane...insanely retarded ! jeeze...i'd start yelling if my car started lagging like a mofo if the turbo went offline
I dont hear a leak at all... and it still pulls super hard!! I just dont hear it at all...It kinda pisses me off...ohh well Im gonna take it to them and have them look at it....Its all free so no worries
I had a leak too!, but it was from my egr valve. the whole bolt unscrewed itself and vibrated all the way up the copper line. My car had no spool and serious lag when it happened. Probably back to the speed of the stock protege it was. It sounded like a 80's ford turck when i was driving. but if you don't hear anything then everything is fine, i woudln't worry. even though this has nothign to do with the vacum, check all your bolts and s*** too just to be safe. happy motoring
