[Blown Engine question...]

[Dan Bubb" <jdbubb@ix.netcom.com (Dan Bubb)]

My 79 had the keyway eaten out on the crank, but it was the old style where
there was actually a seperate key.
My 84  (where the key is integral with the timing pulley ) had a damaged key
when I disassembled it. Not sure if it was damaged in service or damaged
from removing the crank bolt.
Both cars were factory assembled i.e. I bought them new and had not done any
work in this area prior.
So, it's not unique to the 16V.
