ok i know when you install an intake you can hear the turbo better but i also hear my BOV really loud too, is that normal? i'm pretty sure it is but i just want to be totally for sure. also i got my oil changed about 5 days ago and i'm leaking a little bit of oil. someone told me that some cars after getting oil changed will do that for 2-3 days and quit. i still have a good level of oil but i was just wondering if you guys have ever had this happen? thanks
