What did you do, pressure wash it? You know that the cap isn't sealed to the disto right? Water will get in if you give it a chance. I would suspect that MSD figures that the unit will be in a fairly dry environment unless the installer takes some action to seal the cap to the base.

Yup, it looks like it was submerged. No board of any kind will survive that. No wonder it packed it in. Fortunately for dawg, MSD can put in a new board and make it like new again.

thing that gets me is the distributor never seen water?
also there is numerous cold solder joints and the board wasnt coated?
im betting they farm out their assembly work to mexico!

Great. I just put one of these in my small block(chevy)... So far it appears to work fine, but haveing said that I ran out to the garage and pulled the cap. No rust yet. However I live in a very humid and hot climate. And its that way 9 months a year. I removed the 1/4 turn bails that hold down the cap when I installed it. I use the 10-32 screws and tapped holes to secure the cap to distributor body. Perhaps a little dielectric grease around the sealing surface of cap?

That disto has seen LOTS of water. Dielectric grease sounds like it might be a good stop gap until MSD is contacted for comment.

Water damage could be from simple lack of use. Hot and cold, moist storage garage and you got water accumulation. Thats major moisture damage which took some time to rust out the screws and components. Similar to dew on the morning grass.

Its also possible that the unit you purchased was stored (prior to buying it) in a warehouse somewhere that had high humidity. Or even a parts store that had it in a bad area and you bought an already partly destroyed item.
