hello everyone
im rather new to this, so please bear with me if this is a "you should know that" question. i just installed a re-amemiya intake on my 7, unplugged all the hoses and put them right where each one is supposed to be. as i tested my car, i found that while giving it throttle it makes a deeper noise followed by what seems to be some sort of rattling. it seems to do that somewhere around where the oil cap is. i saw the instruction sheet and also saw a picture with an arrow pointing to a part around where the oil cap is, but since i cant read japanese, i dont know what it says. was there a step that i missed, or is this just totally normal?

 

some people like me would hear like a dragon in pain sound due to the air pump and the hissing sound of the turbos spooling get louder, as far as a rattling sound is not normal as far as I know...
