OK, so it looks like I have at least lost the front crank seal just from the amount of oil coming off the harmonic balancer.
But my question is this:
"Is loss of a front bearing common to this engine?"
My question/comments comes from recent events; I have had to repeatedly tighten the alternator to prevent squeal, but this is now something beyond simple belt stretch....
I admit I have yet to crack the service manual, and I hope a simple crank seal (are they simple?) is all I need, but the repeated tensioning has me worried that seals may not be my only problem.
