Timing cover gasket?
Noticed a trickle of oil seeping out of the old Optispark electrical connection on the bench. 
So I took it apart. Looks a tad over lubed to me.
I'm guessing it's time to order a new timing cover gasket? Or is there more to this still?

Easy fix just change the seal behind the opti spark. Do the water pump seall too since it is off. Use a sharpie cap for a install tool. The timing chain cover could be fine a lot more work for it.

Hope your seal comes out easier than mine did. I thought I was going to break the darn timing cover. It was stuck big time! Don't know if the PO glued it in or what, but I had to split the thing with a dremel rotary disk and peal it out. New one pressed in easy.

It won't, of course. And I'll probably break something trying. PB Blaster is becoming my best friend.

since your opti is out clean it up good eagle one etching will make your aluminum shine just spray and rinse. You will not stop there it is so easy.

Eagle One, check. Special tool for pulling the seals? I was so looking forward to reassembly.

NOT THAT that opti seal isn't bad, and it probably is, but you may have other issues.
First is the PCV system working properly? if it is, the crankcase should be under a slight vacumn which should keep the oil in the crankcase; if not, and the crankcase pressurizes, then oil is forced out through any of a number of seals;
Second, its a 95 with a vented opti ? the vent system should pull out ... not just moisture... but any oil that gets past the seal, and its obvious yours wasn't...or if it was, then it was simply overwhelmed by the amount of oil.

But what I needed was already in my toolbox anyway. As it turns out my long 1/2" Craftsman socket was the perfect fit. Slid right on.
