i bought my s15 a few months ago but recently i noticed when the car is cold and i put it in gear this rattle noise comes from what sounds like around the gear box for a few seconds but only when cold,and also when im driving the car cold or hot if i drive pass 3 thouands rpm and take my foot off the throttle from 3 thousand to 2 and a half thousand it also makes a rattle but sounds more like the engine then gearbox,pls help

Doesn't sound like VVT rattle.
Maybe a loose heat shield?

Is it only when you put it in gear? Or does it do it in neutral too?

Is it still on stock exhaust? If it is, it could jolly well be the rusted exhaust heat shields. Just remove the loose ones.

It only seems to be in 2,3,4,5, gears and it seems worse in 5th out of all of them,ill have to try get it on a lift and check it out i hope its only something loose there also seems to be a whine in 6th gear ?
