Cracked dyna coils - typical?

[pano]

I was cleaning up a set of used dyna coils today and noticed some stress cracks where the square rod protrudes out of the casing. I would say one has stress cracks and the other has cracks. I got them from a running bike so I suspect they still work. The coils are dated 1/96 and knowing the bike they came off they have seen some use.

Anybody seen this before?

I've never had that problem with the Dyna coils I've used. I wonder if maybe loose mounting may have caused the cracks...

Never noticed any problems with mine, They've been on the bike for about six years now with no problems.

Thanks guys,

I am going to seal the cracks will silicone, run them and replace if necessary.

I would not use silicone because it will not keep water out. It may appear to be watertight, but it will not be. The better choice is go to Lowes/Home Depot or a Marina and buy a small tube of 3M 5200. I will guarantee that will stop water intrusion.
