Well, After rotating the crankshaft CW by turning the !" nut below the fan, I was able to get at
the two bolts in the filler block. Then after finding out the filler block was still firmly mounted,
I removed the lowest 3 bolts on the timing chain cover and after a little prying it popped off.
There is a gasket behind the filler block and somewhere over the years someone glued the
filler block to the gasket. It does make it easier to reinsert the two bolts if the filler block is
glued in place. A putty knife popped it loose. Make sure to align everything by starting all 5
bolts and then tighten when reinstalling. I did this with the car sitting on 4 car ramps and
two jack stands for safety.
