Pinky and the brain lol. This is awesome content. This is also an awesome find and excellent insight in regards to Opti diagnosis! This is the first time I’ve ever witnessed this ding and discussion. Don’t edit a thing. It’s genuine and great info! Sub’d.
Thank you. I posted it hoping it'd help someone. We actually misdiagnosed the timing chain failure on the 292k like lt1 in the car and pulled it to put the lt4 hotcam lt1 in.
@@GoodnewsBadnewsGarage I really appreciated this. This was my issue. I had gotten a spectra then a cardone. I figured both couldn’t be bad. I have a 96 vette. Have replaced everything. And it turns out it was the Opti. I swapped everything from the cardone onto the delco base and she fired up.
That's awesome. We figured it out by putting cylinder 1 at top dead center on compression stroke and taking the cap off the Opti that was still in the car. Then we ohmed it the plug wires to find out which one the rotor was facing. It was not facing cylinder number 1 as it should have been but two cylinders away. That's why we thought the timing chain had broken.
I just watched your Video. And I'm building a new optispark and I'm having that problem where the rotor and the back where it connects to the cam is off a bit. It's in the same direction but it's off like 1/4 of a inch. Will that cause a problem..
If I can remember to do it I'll throw a video up in the next day or so of testing the sensors with the oscilloscope. We recently found out the high resolution signal on most of my spare sensors was not reading properly. So I had my buddy order a TSP (top steet performance) so m sensor part number JM6942 to replace his.
He is having an intermittent miss/skip (not a dead miss) issue which causes the car you kind of buck on the highway. Mine is doing something similar so if the sensor fixes his I'll be doing mine as well. I chose that sensor based on personal experiences wit TSP optis so far and they are the same optis that were used as Skip White optis a while back. Good luck. I hope it fixes your issue.
I did it just like you showed in your video and there both pointing right next to that screw just the new base is off only by like quarter inch. So , your saying that's to much to be off to run right.
It shouldn't be off at all. I mainly posted the video to show that all the bases aren't assembled the same. I just put them at that angle because I thought it would show the issue. I'm unsure how much it'll throw off timing but if it's off that much it could very well be noticeable. If your old base has good bearings just use the new cap and rotor (and sensor of you're using another one) on that. The oem bases are much better quality and you will know the timing will be good that way as well.
I'm not 100% sure of it, but I think I've read somewhere that the TSP (top street performance) Opti are the optis that Skip White were unsing. The best opti of you can manage to keep the oem sensor alive is to just keep the oem Mitsubishi sensor in good shape. Not always possible and that's where Petris or Skip White came into play. I've never used a Petris opti personally, but have had great luck so far with the TSP units when I need one for a flip car. I keep the Mitsubishi sensors for my own cars when I can.

@@GoodnewsBadnewsGarage wow. I’ve watched hours of video and no one. I mean no one has mentioned this
@@GoodnewsBadnewsGarage y por que no estaba en el cilindro 1
Is ther anyway to realign the shaft to the back where it connects to the cam. Can you move it or press it out
The are pressed in is all I know. I suppose you could press it out and back in but have no extraordinary m experience with that personally.

It'll throw the timing off for sure. If I didn't have other oem AC Delco bases to look at I may never have found that issue either.

Petris opti is the way to go.. Msd doesn't even compare to petris.

I agree, MSD are just as hit or miss as the parts store stuff.
