My son bought a nice '77 Accord recently, with a 1600cc CVCC. The seller told him it needed a crankshaft seal. He's got it torn down and I was helping him pull the seal today. The end of the crankshaft is wobbly, and the pully has been rubbing against the plastic timing belt cover
I suspect a broken crankshaft. But not being familiar with them, I wanted to run this past you Honda guys. I"m hoping you'll say something like "It's two pieces. Just drop the oil pan and replace a coupling". I won't hold my breath, though. Quite depressing.
