How does oil get into an OPtispark?

the long 4 pin connector that goes into the top of the Opti does have a accordian rubber seal on it. Dialectic grease helps to seal it even better
But yeah the Opti is not a 100% sealed unit and oil or coolant can get in it from TC seal, wp or china wall casket/seal leaks

Well I am going for broke. I cleaned the opti up and RTV'd the **** out of including the plug on top. Hooked a vacuum pump to it. It does not hold a continuous vacuum but rather has a slow bleed down. Not sure if even a new opti is absolutely air-tight.
If it does not run right. Im just gonna replace it. Will know this weekend. Thanks again guys.

An update guys.
Turned out my original Delco opti likely was not bad afterall. I ended up getting an Advanced Auto Parts Opti w/ lifetime warranty for $112 and decided to roll the dice. Car still ran like crap.
I replaced the plugs even though they looked fine and then OHM checked the plug wires. Number 7 was giving a very flaky reading so I pulled the boot of and clearly the conductor was not well crimped at the terminal. I re-crimped it and the OHM check went as expected.
Car is now running good again and I will just hope for the best with the AAP Opti. But so far so good. I also noticed one other very nice benefit. I now have perfect 128/128 BLMs at idle. They used to be slightly split down around the 122-124 range.
While I was in there. I also replaced the water pump for the Hell of it since the original one was so old and obviously the Opti seal in the timing cover.
Thanks for all of the assistance.

One thing that hurts me is its heavy. I once weighed it on a truck scale and race weight was 4040 pounds. I guess the duals, 9" rear, stereo equipment and spare add up to a couple hundred or so. Its really all fun street car now days.
It ran 12.5 @ 114 w/ a 2.3 60ft IIRC many years ago but I could not launch it for ****. Im sure a good driver could come real close to 11's like you say.
