If the crack is on the part where the connector fits, you will need a new opti. That part is not part of the cap.

Water pump and crank pulley have to be removed. Hub can stay on, if it is a stock one.

 

I found a complete used unit at a local auto wrecker for $150.00 out of a 94 Z28 like ours. I think maybe we misjudged the unit, this one also flexes if you push on the top wiring connector. I am hoping that we just got it wet washing the engine down it starts fine now. I found that MSD makes a cap and rotor that seem reasonably priced here in Canada, about $150.00. The car is almost 20 years old and always been a race car, so I'm thinking it might be time to change out those parts. Any comment?? Do we still need to remove the water pump etc to change that cap?

 

Yeah, the pump has to come off to to any opti maintenance.

 

I'd like to meet the engineer who signed off on that design............and kick him in the nuts lol

 

lol I think they could have done a little better. That is part of the reason I went to the ltcc and have coil per cyllinder so I can eliminate the cap and rotor maintainance issue plus it gave me simple triggerable retard for when I spray. Dont forget to loctite the rotor screws if and when you do cap and rotor.

Now that it has had a couple of days to dry out it seems to run fine again, the next step is to run it on a dyno before I take it to the track. Is there anyway to test the used opti I bought from the wreckers to make sure its good? I only have a 30 day warranty with it.

 

Looky what I found........................too good to be true????

I don't recommend anything but a GM/ACDelco/Delphi optispark. When you go with the cheap stuff, there is a very good chance you'll get bit. You think you are aggravated about having to pull the water pump to get to the opti now? Wait until you have to do it all over again because of a cheap opti.

 

I found it on a corvette website, and a few of them have had luck with it. The GM unit here in Canada is about $1400.00 lol.............

 

The description is "suspect" at best:

"Ford only"???

Stock pickup, and every aftermarket replacement is an optical sensor. Somehow I can't quite picture 360 tiny teeth on a reluctor generating the high resolution pulses with a lot of accuracy. Then there's the issue of the second sensor required to produce the low resolution, variable length pulses that identiry the individual cylinders. Might have lost something in the translation from Chinese...

 

you dont have to buy the gm unit from the dealership. Buy it online and pay a little more for shipping. I picked my delphi up for $350. That was as cheap as I found and the cheapest ac delco was $450 shipped.

Thanks again to everyone who posted for all your help! The one on the car seems to have dried out and it runs okay. I think I will take your advice and get a Delphi one if we need it.

 

It didnt dry out and run okay lol. Pulled it apart last night and I will post pics of what we found. Think the 19 year old Optispark was in good condition??
Weird it wont let me post pic?

 

You cannot attach a picture directly from your PC (Neither can anyone else). You have to post a link to the online server where the photo is stored. If you don't have a site to upload it, go to UserCP and start an "Album". Upload the pictures. Then you can link to them.
