I got this link from the other forum. It's an interesting story posted originally on Hagerty.

No, article is about a fan failuert on of the forum members had with his engine. He reported it here. I don't remember the poster, but he posted photos and info a few years ago.

Craig - funny you should mention that.

I've parted a lot of cars, had a significant number of mag fans pass through my hands. Only recently (past couple years) have I been finding them swollen, cracked, or broken on engines / parts I buy. Seems like I have about a 75% fallout rate for finding cracks when cleaning them up.

I've been a Corvair guy since 1960. Had 9 of them. I have never seen this happen. I suppose it could have been caused by something hard ( like a wrench ) dropping down into the spinning fan & causing this damage. I can't imagine a piece of magnesium punching a hole in the steel shroud, but a wrench could.

I believe I was going to have one of those fan explosions a few years ago. I had a 64 mag fan on my car and had gone through a couple of fan bearings. I decided to go to a late fan bearing and, because I had a near perfect, pitless late mag fan, I put that on. Looking at the "old" 64 fan, there was lots of bubbles and pits near the root of the blades and on one blade there was a place that looked like it was ready to break off. That fan is just wall art now...

Doug - its not just a piece of magnesium punching through steel.

Its a piece of magnesium spinning at XXX RPM being thrown through steel.

Here in tornado country, we understand how things that shouldnt be able to penetrate something else, can.

Wow Kevin,

I was going to try to resell my old fan, but after reading this thread, and hearing your idea, I'm going to put my old fan on the wall too!

Fans are good if no defects are found on the fan. Defects include cracks, bulging material, broken off pieces of the fan and loss of material caused by corrosion (pits & metal thinning).

I have one that looks good from top, but has bulging underneath at a blade joint. It is a wall hanger.
