<BR>I'm no expert on the roll pin, but...I've been thinkin' about it and 
realized that this shear pin might be a designed in safety feature. If your 
oil pump seizes up something has to give. What do you want it to be? The 
shear pin is the least expensive and least potentially damaging to the 
engine. In fact, if the shear pin shears, then the distr. stops turning and 
the engine stops. This does not cause a boom, but actually saves the engine 
from running without oil pressure...unless I'm missing something...

I'm no expert on the roll pin, but...I've been thinkin' about it and realized 
that this shear pin might be a designed in safety feature. If your oil pump 
seizes up something has to give. What do you want it to be? The shear pin is 
the least expensive and least potentially damaging to the engine. In fact, if 
the shear pin shears, then the distr. stops turning and the engine stops. 
This does not cause a boom, but actually saves the engine from running 
without oil pressure...unless I'm missing something...
