I've read a lot of concern of the opti spark, but in 30+ years of driving, I've never experenced a better ignition. My 94 Vette can sit for 3 weeks, and I just touch the key and this thing fires instantly.

I second that!

I agree!

I agree!

92 LT1 50,000 miles
94 LT1 34,000 miles
96 LT4 85,000 miles

Countless engine washes. Driven in rain more times than I can count.

NO Opti stutters, misses or breakdowns!!! EVER!!!

Best ignition system that Chevy ever designed!!!

Save The Wave!

Consider yourselves lucky. My new one works fine, so far.

Does anyone ever just replace the cap and rotor on these, just for routine maintenace? How long do they last? I see them selling for around $250, which is huge for a cap and rotor. Can it be done without removing the waterpump?

Make sure you find out if something else is wrong that may have made the opti go out, like coolant from the back of the water pump leaking into it. I replaced mine last spring coolant from the weep hole on the pump was getting into it plus it was collecting moisture from sitting on the concrete floor in the garage all the time. I replaced the whole unit with an updated one from Dynatech engineering ( dynaspark ). Now it runs the best it ever, at least so far.

My 92 only has 15K on her and she started having a high speed miss. Well, decided that it was time to pull the opti. It was greener then green, rusty and I could not believe that the car even ran. I kept it as a wall piece instead of the core it was so bad. So anything is possible.

You can just get the cap and roter, but you can not do it with out removing the water pump, another GM brain trust

I had a similar situation. My '94 opti was replaced at about 12k miles. No engine washing, no leaky water pump. Just a bad design and bad luck.

I have the MSD cap and rotor kits in stock for $169.99 (plus shipping), every day. In answer to your question, no, you must pull the water pump. I'm still waiting for the MSD "Billet LT1 Distributor" as the Opti replacment unit is called to be shipped out, as the demand is high for these. MSD makes high quality stuff (I've been using MSD products for over 20 years), and you can be confident in the use of their product.

As a matter of history, I remember back in late 1991 ('92 model year start), GM had a campaign to replace the Optisparks on the first 1500 Corvettes that rolled off the assembly line. I replaced probably 15 myself at our dealership with the "new improved" model (the '92-'94 Opti!), so you can say that there were actually THREE Optispark models, counting the first 1500 "failed" units.

The early opti sparks did have some failures but GM updated in 1995 with a vacumn line that helped keep out mostiure and spark gases. My 94 LT1 TA went thru two in 40,000 miles until on the last one I got the kit that had the upgrade. Do use some sealer around the front to kep mostiure out. My 96 LT4 has 71,000 miles and works fine. And a bad spark plug wire will ruin a opti spark ina hurry, NEVER pull a plug wire while the engine is running.

Out door car covers

I have to park my Vette outside this year (Daughter getting divorce and garge is full of her stuff) there are some many different brands, I am looking for the one that will have the best out door coverage as I live in Texas and we get a lot of small hail. I know none of them will protect against large hail but which one will do the best and not rubb the paint of the car when covered? Noah has a four layer one and Coverking has a light weight one?????


Darn I thought I was starting a new topic, Sorry
