I haven't noticed many major opti-spark problems NOT caused by water. I've had more ignition module problems. But then again, I've had less than 80 LT1 cars over the years.

I wouldn't know why in the world GM would recall a 12 year old product, even if it was junk. Heck, look at the water pumps in the late 80s L98-they would fail at 60,000 miles just like clockwork, the list goes on.....

There is an article in the latest Corvette magazine about replacing the Opti. Lots of good words about coils but the opti stays. I don't have one so I fail to understand the point.

I think the jury is still out on MSD myself. I have read plenty on the failures most right out of the box. That and the denying nature of the support staff make me wary. I know of all the aftermarket ignition systems/parts they seem to be the best but that bar is not very high.

I keep saying this, the Opti-spark should have never been used in the first place when they had better tech to use in the first place

GM should have stuck the HEI distributor on the front of the engine.
No distributor, Opti or not, can withstand coolant poured all over it, don't blame the Opti, blame the poor location GM put it.

Too bad no one ever came up with an adapter to put the opti in the rear of the manifold .There is a gear back there..... Oh just wishfull thinking I know it would not fit.

It certainly would solve a lot of issues wouldn't it. Too bad the engineers didn't come up with that idea.

Space is limited back there, but if there was an aftermarket bracket to mount the opti at the rear of the engine and it looked neat like it belonged there I would be all over it.

MSD going on.... My car only had 45k on it when the opti crapped out. There was some oil in it that made a nice fog over everything in there. The previous owner had the pump replaced but don't know about any service done to the Opti. Also there was 160 thousandths between the tip of the rotor to the contact posts and they were all roasted! That coil must have been busting it's little *** to throw a spark across all that and a plug gap too! Finally gave out, got jerky & check engine light.

The second biggest reason they go out the infamous intake oil leak and the opti shaft seal.. Another good reason not to neglect doing the gaskets and using "The Right Stuff" instead of regular RTV when you see them leaking under the TB. On the new opti's I have seen the area where the plug is has a very bad seal of RTV around it which will allow oil to get inside it.The one I built to upgrade my last 93 with a 95 cap and vent system(see my picks) I made sure that weak spot was sealed.
