Review on 🔌 Remanufactured ACDelco Professional Ignition Distributor (Part #19383531) by Meechie Camlin

Like most of you reading this you probably have a suspicion of an Optispark problem and have read that there are no good Optisparks out there including those from established high performance brands, and that the best Optisparks gets one from Delco with a Mitsubishi sensor. You may also have read that they are no longer manufactured, as I did. When I saw them in stock I quickly ordered them but quickly became disillusioned. I knew it had been rebuilt so wasn't expecting cosmetic perfection but there was a grinding noise as the shaft turned so I had to investigate. I disassembled the distributor and found a few unwanted surprises. The scratching noise came from a bent optical wheel that could scratch the optical sensor, which appears to be the most important part to protect. I also noticed screws of different sizes, one of which had been snapped off and replaced with a larger screw. It's not perfect but I know in a renovated part it would be considered acceptable. What is unacceptable is the presence of pieces of plastic inside where the edge of the distributor cap has cracked, possibly due to rough installation. There were also metal shavings that were not left over from machining, grinding, or other processes. The shaft was attached with a weld instead of a pressed-in pin like the new distributor. It's arguable that a weld is better than a pin, but it seemed like a way to compensate for a worn or damaged part rather than improve reliability. Despite all these issues, at least one valuable Mitsubishi sensor was found inside, rumored to be the only Optispark sensor you can rely on. different than on my old distributor and would not connect without minor modification. After removing the old distributor, which I suspect is an inexpensive no-name brand, I noticed that the Delco distributor had less play in the shaft, although the old part's low play indicated lower quality or slight wear and tear. I do not know. At least the new part worked. I didn't notice any difference in how the car drove, but it did. Now I expected to have a dealer I could rely on for a few years, but the next day the car wouldn't start. Tried a few things besides the allocator because it couldn't be, but as it turned out that was it. I ended up unplugging the respected Delco distributor with the Mitsubishi sensor, plugging in the old one, hand cranking and could Getting spark and fuel which I couldn't with the Delco part. I sent the distributor back for a replacement, another Delco. This one looked better overall, no cracked parts, no bent wheels, no mismatched bolts and a pressed pin instead of a weld but NO MITSUBISHI SENSOR! If you're buying a Delco to get a Mitsubishi sensor, you're taking a risk as I've learned firsthand that not everyone has one. After one failure, I no longer felt it was important to have a Mitsubishi part, so I installed a Delco replacement with a mysterious sensor. The machine will continue to work normally after a few months. Next time I need an optispark I might try the cheap one as I don't know if there is an advantage to buying a part from a well known brand. Now I'm wondering if I even need a distributor. The machine ran rough and issued an Optispark code. Replacing the distributor didn't help, but cleaning the two clogged nozzles did. The previous owner did quite a bit of work on the car which may have really needed and replaced a distributor but never got the car to run properly and may still have the old codes on it. Once cleared, the codes were not returned to either the new or the old distributor.
