Hey gang,
Okay so I put everything back together on the 84 gt. now I pulled her out of the garage today and timed her and she was purring like a kitten.....after about 5 minutes I was hearing a deep thumping sound like: metal on metal.....at first I thought it was maybe my exhaust but when I looked it was okay.....so I gave it some throttle and the thumping was consistent with the acceleration of the motor.
My question is WHAT THE HELL IS IT!.....
I changed the pullies and put on some underdrive, but that was about all I have done to the car.
Could the underdrive be causing the crank to go out of whack and make it thump....or the harmonic balancer...how do I test this....my neighbour is guessing that it might be a connecting rod.......
I need some advice people!!!!
Thanks for everything
Rick
