What preventive maitenance is done on either crankshafts of connecting
rods?


Oil changes for one.

Well there is no maitenance on connecting rods and crankshafts.


...other than .preventive

I don't have any personally but I have a friend that has had three
in
3500hrs. One connecting rod failure in a 210. A crankshaft
failure
in
an
Azetec and I forget the details of the third failure. It has been
estimated
that 10% of Malibus have had inflight engine failures of some
kind.


It'd be interesting to know the maintenance history of those birds
that
did
have failures (skimped maintenance, etc).

It's also be interesting to know the total operating hours of the
Malibu
fleet, Lycoming vs. Continental...

Oil changes do not affect the probability of crankshaft or connecting rod
failure..

So having bad or inadequate oil to lubricate the crankshaft and connecting
rods don't make much difference? I must be working with different engines.

Presumably you have never worked on an engine at all.. Please describe how
changing engine oil keeps a connecting rod from breaking in half.

Please lose the patronizing tone that you came into this discussion with,
then I'll continue with my QUESTION. (No wonder that one guy said he came
into the group, then left after seeing the abuse some dole out.)

Sorry for the tone but it is incredible to me that anyone thinks that
changing oil protects against structural failure of a crankshaft or
connecting rod. Yes changing the oil makes the bearings, gears, cam/lifters
and all other rubbing/sliding parts last longer but it does not affect
cracking one bit.
