Default Poll: Opti Failures.

If you have had an Opti failure, tell us the mileage when it occurred. If you are on the original, tell us your mileage.

I replaced my original 113k mile opti when I was in there for a cam swap. It still looked great and probably did not have to be replaced.

Are you still on the original plugs and / or wires?

Changed mine out as well at over 100k.

When I did change it out it was my choice, it was still working fine.

96 LT1 w 126762 on the odo.

I acquired the car @100k. Judging by the layer of crud that was on the front of the engine I don't think it was ever apart. I have had the distributor out when I replaced a leaking water pump @ 110k. It was immaculate inside, however one of the plastic rivets that retains the rotor blade was broken and the blade was flopping around. So I installed a NAPA cap and rotor kit and plug wires at that time. Runs perfect.

Plugs have been changed, but the wires are original.
Everything still looks brand new and no arching in the dark.

I replaced my original @30,000 since I was putting in the new motor, and it was a bit cruddy inside. I replaced it with a new A/C Delco, that I just replaced with about 15,000 on it. The car was missing at high rpm. I found the rotor with one screw out, the other loose, and the rotor centering pin broken. The inside was a little oily also. It's prolly still ok, but I replaced that one with a MSD this past weekend. So far it's smooth right to 6800rpm.

I replaced two optis in my 94 by 20k miles. The third I upgraded to the 95/96 opti, and have been good for 8k more miles (knock on wood).

First was OEM around 50k miles, due to water intrusion
Second around 25 kmiles more, it was genuine OEM. Next was with new motor around 115000 miles by odometer. Then the dilemma began, when they started breaking (Dynaspark, OEM blah blah). Install is so important. ABout 3 more, finally cut rotor off went with DELTEQ.

My first lasted to 70k miles. Including Hundreds of timeslips at the local track. I literally have 4 old harddisk boxes full of slips. Then it died and replaced it and had no issues until I went rear dizzy.


Out of curiousity how many of those who claim <25k miles are 100% sure it was the original opti? sounds to me more like a bad batch of replacement parts.

True, I bet some were replaced after a random car wash via warranty, especially 92-94's.

Original Opti at 96K. Did replace the cap and rotor at 80K while installing the hotcam (while we were there thing). The original was still in good shape, just showing minor burn marks. It also survived a waterpump failure with no troubles.
