You can only hear the noise while driving the car in drive. While driving and you put it in neutral the noise goes away, put it back in drive and the noise comes back. It will not make the noise in park,neutral or reverse only in drive or the lower gears when moving.
Classic exhaust leak,. Look for cracked headers and blown gaskets before turbo. Black soot is giveaway.
Thanks..... I have changed out the driver's side header with a Poston drivers side header, replaced the passanger side header eith a stock header, had the both stock headers resurfaced, tried the Felpro 1400 header gasket, used ultra copper rtv sealer eith and without the gaskets, used studs in place of the original fasteners and replaced the crossover pipe with one from TAPerformance!!!! However due to the noise only occuring while the car is in motion and under a load I tend to think that it would be exhaust related....WHEW!!!! Sorry for the long post!
Thanks for the reply..... I have tried that several times and nothing!! Like I stated earlier it will only make the sound while in drive moving and foot braking! It will not do it any other time.
Someone once mentioned a broken front pump vane inside the transmission, if thats the case would the sound be present in all the gears?
No I have not tried foot braking it on the stands.... Good suggestion I will try that this evening.
Hey dynoman if the noise is not heard while foot braking the car on the stands should indicate an exhaust leak right?
I tried foot braking the car while on jack stands and the noise did not occur. I know that it's the holidays so thanks for all your help and Merry Christmas!!!!
Merry Christmas Everone!!!! I swapped torque converters and the noise was still there, Ian's yes the tapping/metallic noise can be heard with the windows down and when driving. . I jacked the car up last nite and foot braked it and the noise was not there however if I foot brake the car on the ground the noise is there which leads me to believe that it's exhaust related. I have swapped headers and tried the Felpro.1400 gaskets with no luck maybe the Remflex gaskets will fix it.
After thinking about jacking up the car and foot braking it last night and the noise was not there I don
I installed new unjointed from Autozone. I do have a really bad vibration (before/after the unjoint replacement) which makes me think that it could be rear end or brake related.
