ok sry the engine is a d16 and also the idea of the timing struck me because it does sound like its coming from under the timing belt cover. also the noise only occurs when he steps on the gas and it gets a lil louder as the rpms go higher. also no there is no plastic bag lol we checked for the first. also when you said brake booster I dont know excactly what that is but I know his brake lights are stuck to on. I donno why but he said something about a lil rubber piece that grounds the tail lights when you push the brakes and he said he thinks that came off. any ideas? thanx for all the help.
