Strictly speaking, many of the Tech4's problems in the Fiero were related to the shallow oil sump, necessary for packaging, that had it always effectively running a quart low.
I can't say I had heard of one losing teeth on the timing gear-but I don't doubt it either. My biggest gripe was that during the design phase, balance shafts were left out for cost reasons-it feels and sounds far too industrial for a small car engine, relative to its output.

Likewise, the AMC 2.5 that they designed to replace the Iron Duke in Jeep applications was, despite being a truck motor, smooth enough to put in Eagle Premier sedans.
