Thanks again every one!
Yes timing cover has fuel pump boss, and balancer is a four bolt. As I have tried to consolidate TDC at aither left or right side of the engine, (cannot be done) and since I have no reason to believe the harmonic balancer has ever been replaced, I have to assume it has either spun or degraded. Either way it must removed and inspected.

I am anticipating thiis procedure to be a real chore. Do any of the large chain auto parts stores loan or rent pullers and presses? If this has spun, is there any danger the force needed to remove damper from crank will damage the crankshaft?

I am just thankful I thought to check this out prior to pulling the distributor..and to have the collective knowledge of this forum! I will report back after I determine true cause, or if I am back at square 1!

Thanks again.
