Rattling sound around engine?
so, I took the car for its bi-monthly spin today to make sure the battery stays charged up, and everything is holding up.
I decided to roll with no sound and the windows down today, and noticed a rattling sound coming from the car.
I tried to isolate the sound and find the variable and location as best as possible.
It sounds exactly like a heat shield rattling. As I got back home I checked it out, revving it as it sat parked, and the noise happened during the deceleration of the motor during the revs. As I listened, it almost sounded like it was coming from around the turbo.
Some info on the car:
j-spec 13B-RE
Microtech LT-8
550/1680 injectors
tuned by steve kan
Im not sure if something inside the motor could be rattling, as it revs up its pretty smooth, but im definately worried about it.
As soon as I can get my hands on a compression tester im going to check it out further, not sure though if it will yield any info.

Small cracks on it usually make a weird sound, at weird times, that ressembles a rattling sound. Wouldn't hurt to check since it doesn't sound like anything serious (hopefully) and it's in the right area.
