Update--Still no start today and now throws a code 16 I guess it's time to tear it apart. I have another opti unit but do not know if it is any good , Also where can I get a good deal on a new opti unit and is other ones as good as the gm unit.
Thanks again for all the help
Steve
I also went with thepartsladi optispark. I'm a little worried now because all the packed on grease is no longer there to protect it. I drove around for several months with the water pump leaking on the stock opti and it never died. I was adding at least a gallon of coolant a week. The only reason I replaced it is because I was already in there for a cam swap.

The new thepartsladi opti...
Original 118k mile stock opti insides after removal...
Hey Rick...you got your WP coupler on backwards !
(not sure it makes any difference though)
I can't believe how clean the inside of your old Opti is considering the gunk on the outside.... I guess you
were right that all that nasty goo makes for a pretty water tight seal !!!!!

Looks pretty good.
That's the improved, vented Opti for '95-1996 LTx engines, right?

If you check the after pic you can see where I had the timing cover welded shut for my electric water pump.
I was also surprised at the inside. I think the people that seal the opti with sealer are definately on to something. I wish I had done that but didnt think about it until after everything was back on.

Yes, Both are 95 opti's.
Mybad !! I should have picked up on that. Do you have a pic of completed front end with the electric WP ?? Just curious to see the finished project....

All the engine is back together now. I still have to put the radiator back in. I forgot to take a pic on Sunday. The car is an hour north from me. I work on it at my parents house where there is more room. I will post a pic on Saturday when I get back on it. I'll post a start up vid with the new cam also.

I have always suggested a good seal of "The Right Stuff" around the cap ,plug & backside screw area especially on the Gen I optis the seal at the plug is useless. The Gen II plug area is a little better but still nothing like a little insurance. Your guts looked pretty good really and yes the oil gunk did help to preserve it I am sure. That is the reason I did not do a really good clean up on the front when I re-did my intake gaskets.
Pulled it apart today and there was water in the opti unit all you guys where right THANKS ,I have a MSD unit on the way=--should I seal the weep holes and around the cover with silicone or are they a better design when it comes to water--
