Awhile back I posted that the drive had failed. Well I diagnosed the problem without taking it apart. /forums/images/graemlins/shame.gif The failure was the oil pump, it locked up. That was the horrid grinding noise, it sheared the shaft and steel coupler sleeve and wiped out the distributor. Grinding gear noise plus screwed up timing led me to believe that the drive had failed. As soon as I get around to it I am gonna take the pump apart to see why it locked up. On a side note with gear drives there has been some statements as to the harmonics wreaking havoc on the cam bearings. It appears that statement is true. The #1 cam bearing had started to delaminate, pock marks all over the surface, could be one reason the oil pressure started to drop. Or between that and the pump... who knows. At least it did it in the driveway.. /forums/images/graemlins/waytogo.gif It's a shame that's the end of the 73, that was one awesome rig.
