Cautionary
Tale of What Can Happen to an Iron Duke if the cam
gear breaks.

It took four months, but my Fiero is finally back
home after a catastrophic Iron Duke engine failure
on July 16, 2015
The cam gear, which on Iron Dukes is made of a
pressed fiber material called Micarta (and meshes
with the metal crankshaft gear), shattered and
allowed the cam to walk its way into the engine
block. That threw off the timing and destroyed the
valves and valve lifters, and cracked the valve
guides, which destroyed the cylinder head.
3 months, one new cylinder head and camshaft gear
and many hours of labor later, my car was ready. It
took another three weeks to get the money
together to pay for it all. But that's water under
the bridge. My car is back home, and after 31 years
of faithful service (I've now had this car MORE THAN
HALF MY LIFE), the wait was worth it.
As always, many, many thanks to Dave Armstrong at
M&D Auto Care, a factory-trained Fiero mechanic
without whose expertise my car would surely have
ended up in the junkyard. If your Fiero has a
mechanical problem you can't solve, he's the man
to see.
