IML DIGEST rebuilding 440 in 1968 Crown

["Phil Patterson" <hilljack7@xxxxxxxxxxxxx>]

I had that happen on a440 in a 73 Town & Country I once owned,and it had
about that many miles on it. But, I thought plastic coated timing gears
didn't become an industry wide thing till 68. I remember my dad's old
Catalina having to be fixed by the dealership, but I'm not sure right off of
the top of my head when Chrysler changed to these. I would assume post-68
though.

Imperials ('66, '67, &'68) experiencing a failure in the timing gears and/or
timing chain right around 100,000 miles. When disassembled, the problem was
usually due to the excessive wear in the synthetic coating on the teeth of
the gears.

at much higher mileage. Has anyone experienced this with their cars?
