Optispark...

[Curious George]

I've just received my MSD Optispark. Hopefully this is the last time I will have to replace it. I replaced it previously (Not an OE one) and had a bad feeling about it.

I also need to replace the front crankshaft seal, so I am going to do that as well. Of all the quirkie things on the later C4, the Optispark has to be the number one item that leaves you wondering "when will I get stranded". It is not a matter of "if", but "when".

Luckily for me, mine stalled in the driveway coming back home last week. POS

Seems that way but there are lots of things on other cars (Vettes included) that can leave you stranded.

The OptiSpark ought to be a time change part rather than a replace when if fails part - but what's the mean-time-between-failures.

My '92 had its OptiSpark fail and leave me stranded only 10 weeks after I bought it. Then again, the early '92 was recalled to replace the first generation Opti - mine was an October '91 delivery. Couple of monts later, GM asked me to have that one changed as the original replacement was another first generation Opti. Had that done with a second generation Opti and it was still running strong over 10 years later.

I concur.

However, at the time I was writing my post, I was just thinking how putting an optical sensor in an ozone enriched, high voltage environment was not good engineering sense.
