I've noticed a sound coming from the engine, to me it sounds like the knocking or tapping sound made when the oil level is low. The sound is only noticeable when I press the pedal down pretty good to accelerate, it's pronounced enough that my girlfriend even notices it and she doesn't notice much with cars. I've checked the oil level many times and even changed the oil and the sound persisted. I've been leaving it alone because I've read a few threads here saying the GDI is just loud, but I just feel like it could be something other than the high pressure fuel injectors ticking.
Thanks for any help!
