neoniacin Posted November 15, 2018 Share Posted November 15, 2018 Hey all, So truck is running fine but noticed that my ignition module is leaking. I’m going to replace it but was curious if there is something else besides the module that could cause something like this. Link to comment Share on other sites More sharing options...
Ford F834 Posted November 15, 2018 Share Posted November 15, 2018 Interesting. I’ve had a couple of them leak sand like granules that surround the components beneath the resin, but I’ve never seen liquid leak out of one. Definitely replace it, I’ve never heard of anything the causes modules to fail other than just an old or faulty part. Link to comment Share on other sites More sharing options...

It is like it got super hot to melt it then cooled off after it ran a bit. Replacement is on the way. Link to comment Share on other sites More sharing options...
Ford F834 Posted November 15, 2018 Share Posted November 15, 2018 Yikes. Yeah, you can’t tell that from the picture, it just looks like wet oil or something similar... Link to comment Share on other sites More sharing options...

I had one leak in my shop and get goo all over things. And the shop wasn't hot, so I don't know why it leaked. Link to comment Share on other sites More sharing options...

Gary Lewis Posted November 15, 2018 Share Posted November 15, 2018 What was the story about using the wrong Coil on a Duraspark ? Haven't heard the story, but did that melt the "goody" out of the modules? I can see that happening. Link to comment Share on other sites More sharing options...
NotEnoughTrucks Posted November 15, 2018 Share Posted November 15, 2018 I hope you will post a pic of the backside of that ignition module once you remove it. There is nothing liquid inside the module and I don't think there is anything that will liquefy with heat. Is it possible that there is a hole in the inner fender underneath the module that would allow liquid to collect between the module and the inner fender?

1986F150Six Posted November 15, 2018 Share Posted November 15, 2018 What was the story about using the wrong Coil on a Duraspark ? When I first made the Duraspark conversion on my truck [1986], I maintained the TFI coil and quickly melted the resin in the ignition module.

The “leak” isn’t wet to the touch. It is hard like plastic. Looking back at some pictures of the engine bay show this has spread over time. I could see a little bit of the “leak” in the corner of the module when I first got the truck. Just didn’t notice it. Would it be advisable to replace coil too?
