Tracy, the bearings I am speaking of are on the water pump side of the engine. The pilot hole is on the psru/prop side of the engine, isn't it?
That pilot bearing gave me fits to remove.. we had to dremel it and pry it out.. but it was all out to my knowledge.
Im pretty sure the end play was correct - I either talked to you or bruce on the phone a while back (2004?? 2005??) when we got to this stage because my end play was a little low - 2 or 3 thousands too tight.. and it was fixed by wetsanding the spacer (with the letter on it to denote size) for a bit to bring the end play into range (rather than ordering a new spacer)
I am guessing it happened with the pully swap months later.
The coolant issue confounds me though.

The Thrust bearing thing bears more thought. Lynn's point on the redrive installation is worth looking at closely. This assumes you are sure the end play was right before installing the drive. BTW, I once pinched a thrust bearing when changing to that Racing Beat pulley. I was trying to do it while engine was on the plane.
About the only thing that could go wrong is for the input shaft pilot to have interference. That hole in the crankshaft must be clean and empty except for a dab of grease. Are you sure there was no piece of the pilot bearing (used with manual trans) in that hole? Look for any other possible debris in there before re-assembly.
