Its true. I have a 1992. 1992 was the first year the optispark made its
appearance. Optispark was a great idea but the location of it was
downright stupid. The original optispark did not fair well when it got
wet. The stupid thing GM did was place the waterpump right over the
optispark. When the waterpump or optispark fail people usually change
both. Might cost you 1200-1500 to replace both. I think 1995 the
Optispark was replaced.

No my 95 Had an Optispark ..and so did the 96's....
BUT in the 6-7 yaers I owned it tit never gave me any trouble....

Optispark units can be had for about 300 bucks now... far cry from the
original prices...No idea of what water pumps are going for been a
long long time since I had to replace one on any of my cars (crossed
fingers) ....

The reason to replace both is just to save time.. (and labor charges)
since the water pump etc has to come off to replace the optispark...
BUT IF nothing is wroing with the optispark whay sopend 300 or so
bucks to replace it... BUT IF YOU DO replace it with a 94 or up
unit, that has vents for mositure ..

If they pour coolant all over the distributor while changing the water
pump then it most certainly could be damaged, but if it runs now it
should run when they're done with it. On the other hand, if the
Optispark is near the end of it's life then the water pump will have to
come off again to replace it when it fails.

$650 just for the water pump is a very steep price (that would pay for
the parts, a shop manual, and a very nice set of tools).

If/when you have the Optispark replaced, a new model cap will fit the
old model distributor. The new model cap comes with a vent tube. The
old model distributor can be modified to accept a vent tube. One hose
to vacuum and one hose to dry filtered air will prevent future
problems. No flat-rate mechanic will do this - they just don't have
time.

Water pump AC Delco part number 252690, OE# 12509653 (#88926204)
106.79
I see that AC Delco has stopped building the unit for $417 and now
sell it in parts. A1 Cardone has a rebuild unit for $185.79 with a $50
core charge. It has been a while since I was into one of these so
correct me, as I know you will, if I'm wrong. All of them were vented,
that's how they got moisture in them, so you need to vent into a
vacuum to keep out the moisture as they started doing in '95.
