A couple of weeks ago I decided to change the spark plugs on my Omega. After changing them I had a slight misfire, which was traced to a faulty plug lead, so I changed the leads, no more misfire.

When I examined the leads I came to the conclusion that they may never have been changed during the life of the car.  With this in mind I thought that the dis pack may also never have been changed. So I decided to change that as well (hence the title, "Was I mad", for changing something that wasn't causing any problems)

When I got the dispack out, no plasters needed (which I found easier with the removal of the wiper mechanism).  


This is what I found  





Interestingly it still worked.


Wasn't mad after all, it was a good decision, prevention is sometimes better than getting an earful from SWMBO when the car breaks down

Looks like you've done the right thing

Mad no definitely not ..... its called preventitive maintenance.
It was just bad luck about the leads

i am very much a prevention person , for that exact reason!

I dont think it would have been long before the Dis pack started to play up.

equally it could have lasted for months or years . . You cannot tell . . I had one like this on my elite once but never any trouble.

It depends on many things.

The bottom line is that the spark voltage would be lower as a result of the above and this may well affect economy slightly, it could also affect engine response etc and you might not realise....until it drops onto 4 cylinders!
