Hello all. I have a 1988 Supra, 5-speed, NA. I have recently done a top end rebuild. It was running fine for approximately 7 weeks and now I am experiencing a tapping noise that can be felt at the air intake chamber and you can also feel the vibration on the shifter and sometimes the clutch pedal. The car drives fine, but the noise is very annoying. You can hear it at idle and also while driving. If anyone out there has knowledge of what the problem might be, it would be greatly appreciated to know what ails my 7M-GE. Thanks.
