Hey guys so I just recently jumped in to a 2006 boxter s and I’ve been hearing this noise on start up and while I’m driving. It seems to get louder when the engine is under load and is either drowned out by the exhaust note or goes away around 4k rpm. Doesn’t seem to get any louder or quieter when I drive it for a while. At first I thought it sounded like an exhaust leak but from under the car it sounds like it’s coming from the top left of the engine either by the air box or in the head. What do you guys think?
