FORGETABOWIT,
if you hear noise('s) later, likely most prominent... when clutch engaged (pedal up) out of gear ... low RPM...you know where to LISTEN.
You can positively stop the input shaft by engaging 4th gear with shifter, clutch pedal to floor, to see if sound varies.
Really no way to SEE without a flexible lighted camera wand.
.
IDK about packing the crankcavity with grease, never did that myself, just the bearing.If shield dislodges, the grease is going to move outward with RPM and heat, hopefully the flywheel cavity catches it... and it comes out the hole, if there is one, should be visible on engine side of flywheel if grease moving and it has a hole.
Hope I got that right, hope it all works out for ya!!
At work and strange goings on here now, a lot on my mind!
