Those bad designs, I believe, are done on purpose. It gets people into the dealer shop. If you think the wp seal is bad, wait for the fun you'll have with the optispark distributor.
Words of advice. Buy a $70 PC based oscilloscope. It is the only 100% way of checking opti low & high resolution signals. Also good for the pesky 50 hertz fuel enable signal that security system sends to pcm to enable fuel injector operation.
And when opti fails, buy only GM,Delco, Delphi, & Msd. The rest are garbage.
