Dissecting the bad opti - pictures! So I had a thread recently where I mentioned the car ran bad with a new 'thepartsladi' optispark. Today I decided to take it apart and look for anything that was obviously wrong.
This opti probably has a maximum of 2 minutes of engine running time on it along with dozens of attempted starts.
The cap had all this brown dusty stuff in it.
And it looks like it might have come from the rotor here. It looks like it was grinding against something big time.
The little disk has evidence of rubbing on it as well. (On a side note I couldn't believe how flimsy that thing was)
It never threw any codes. I think something was either the wrong height or size and caused all the contact. That probably threw off the timing.

I had the vacuum and air line hooked up. The cap is a pretty rigid plastic. Are you sure there's enough vacuum in there to pull it down onto the rotor like that? It definitely looks like the rotor was smashed against the cap though. And the disk was making contact with the optical unit or something.

FWIW, I just picked up a Cardone reman from autozone for my '93. It has a Mitsubishi sensor and GM trigger wheel. And some nice little plastic washers to delete the rotor for my delteq setup. Be aware that the cheapest one with the lifetime warranty does NOT come with a cap and rotor. By since I'm not using them I just reused the old cap with a bunch of "Right Stuff" gasket maker.

The retaining screws for the rotor came loose, causing the rotor to "****", and scrape against the inside of the distributor cap. YOUR picture clearly shows there the rotor "sanded" down the ribs inside the cap....
