Adam,
Does this noise occur while in gear, foot off the clutch
pedal, and driving down the road... if so, time to inspect
the transmission further.
The four speed has a nice bottom plated bolted to
the transmission. You can remove that plate (14 bolts??)
and inspect the countershaft with the transmission in the car.
There should be NO up and down movement of the countershaft.
If you spot little "needle bearings" that are about 1/16"
in diameter, and about 3/4" long, those are the needle bearings.
DO NOT DRIVE the car until they are replaced.
To replace those bearings means pulling the engine & transmission,
but catching it before any gears get chipped or broken will save
$$$ in the long run.
Cheers,
Tom Walter
