Yes! I've read about that - somewhat scary.
The keyway on the end of the crankshaft can be destroyed if the crank pulley bolt (a) simply loosens over time; (b) or was re-torqued incorrectly after removal; (c) or the key was inserted backwards in the keyway on reassembly.
The result is the crank pulley develops a wobble that wrecks the crankshaft end = need new crank/engine.
I will be looking for evidence of this:
Resulting damage:
^ That
should be a clean, straight keyway.
It's a fatal flaw in the 1.6L 1st gen engine with the "short nose" crankshaft pulley end.
There's also a "loctite fix" procedure that may work if the damage hasn't progressed too far.
