Default Best write up on Optispark install?

I'm know I'm not alone searching for a comprehensive write-up on replacing an Opti. Anyone know of a good source?

How about something a little less generic?

There are certain things specific to year model, but you don't give that info. What's too generic for you?

Mano K. (1badzee) did one a few years ago on another forum, pretty good pics with it:

Shbox, I've browsed your site but perhaps I'm just not able to navigate it correctly. I've got a stock 95 lt1 formula with a bad opti. New opti comes in today (OEM replacement). I found a website the other day that had detailed photographic instructions on how to perform an opti replacement but have since been unable to find it again. I've searched the threads meticulously for something similar but with no luck. Any help would be appreciated.

Edit: Gojira94, this is pretty much what I'm looking for. Thanks!

It just isnt that hard of a task to do..Remove water pump,remove crank pulley (not entire hub) label plug wires remove opti .. seal new optis cap with silicone and locktite the rotor screws.. then reassemble ...its not like your rebuilding a small block
short of a few mundane details..There's your write up
pick up a Haynes manual

Well to most everybody else his site is a God send! Rob has been on these boards for more than most and has been a very valuable member of all and has always been gracious with his knowledge. I am VERY experienced with these motors and I still use his site. There is not a more detailed nor complete site abound.

You can pick up info from any of the boards, but I doubt there will be any as accurate as listed on that site. Hell it even tells you the size wrenches you need lol

Anyways good luck with the job!

The hardest part about doing a opti swap to me is draining the coolant. It's pretty simple once you've done it a couple times.

Sorry if anyone thought that I was insinuating that shbox's site is generic. What I meant is that the link "www.shbox.com" wasn't providing me with the specific write up that I was looking for. But thanks to everyone helping me out with this. I'm still very much a newb to all of this and you guys have provided a lot great information.

Generically speaking, the answer is on shbox.com, but the details are in the beginning of the cam install guide.

My butt has been saved more than once thanks to www.shbox.com

Having said that, I have one piece of info at add:

Once you've got your Opti's pin hole clocked properly, place a sharpie line on the 6 O'clock position on the outside face of the metal disc on the Opti. Then, when you are under the car trying to line the pin and the pin hole, use that sharpie line to ensure your Opti has not rotated out of position. This "sight line" makes aligning an Opti almost easy!

Have Fun!

I'm not a mechanic and am attempting a engine rebuild. I'm at the point of trying to start and all I get is cough and sputter. After reading I'm concerned I may not have installed Opti correctly on 1996 C4. I didn't think it could be installed incorrectly so when I installed I simply lined up the marks.

Is there anything more to this on the new style Opti? I've triple checked plug wires.

This is all you need to know to index a pin drive opti.

Is this a GM opti or a cheap parts store one? If the later is the answer, that is your issue.

Thank you for the information but please understand I installed this over a year ago and project was interrupted by injury/surgery so I don't remember. I do know I'm having some sort of problem preventing start and I'm just going through process of elimination.

From what your article describes, there is only one possible way for the Opti to go on (1996). Is this correct? (yes or no)

If yes, then I should be able to eliminate the Opti as the source of my problem as I'm getting spark to plugs.

I honestly don't know. I reused the Opti that was on the engine. As far as I know it's GM. Don't know how I would tell.

I hope my issue isn't the Opti and timing. I'm getting spark to plugs.

There are more possible ways to put it on wrong than there are right. Only the right way works properly.
