<VV> too much trans fluid causing an ominous knock?

[Jedd Hebrink]

Thanks to the many who have responded with helpful information on this
topic.  I understand the transmission fluid level question now, and it makes
sense that after sitting in my shop for several months, the fluid leaked
down.
 
The knock sounds more like a con rod knock, not a detonation knock.  I have
checked compression in all six cylinders, and found them to all be
acceptable.  When I rebuilt the engine a few months ago, I did install new
pistons, sleeves, rods, and bearings.  I did NOT use Plastigage, and I think
that I am learning this lesson the hard way.  Many of you reminded me that
one should ALWAYS use Plastigage when rebuilding an engine.  Armed with
Plastigage, I am prepared to split the crankcase and measure bearing
tolerances.  I suspect I may have spun a bearing or otherwise created a
problem with the crankshaft or connecting rods.  I won't go into the long
story again now, but the bearings I received from one of the popular Corvair
vendors were not packaged well, and had tumbled around in transit.  There
were several gouges or deep scratches in some of the bearings.  I posted a
question about this before I put the bearings in, and received differing
opinions on whether I should use them.  I took the easy way out, and
smoothed the scratches with some fine emory cloth.  Now I wish I would have
waited and purchased new bearings, because I suspect the scratched bearings
may have something to do with my current problem.
 
Pulling the engine is not such a difficult thing to do, so I plan to go
ahead with that over the next few days while I am off from work.
 
Thanks again for all the valuable advice; it is much appreciated.  Happy New
Year to all!
