Also spent a bit of time with the burrs to clear out the casting debris and stress risers from around the bottom of the block around the crank journals.
This casting debris is from the imperfect casting mould that leave small sections of iron/sand mix still attached to the main casting. In certain situations, harmonics can release bits of this debris which then has the potential to destroy the bearings, an engine, by being circulated by the oil system.
Stress risers are similar. They’re very fine ridges in the casting that can form a weak point. Simple remedy is grind them back flush.

Hi all,
Has anyone driven to Switzerland (e.g. Geneva or Zurich) in late December?
What was it like? Is it possible or does the weather make it a no-no?
Also, has anyone driven in Switzerland in December?
We are thinking of going there but I am not sure whether to:
a) fly there and use trains;
b) fly there and hire a car;
c) drive there and use the car everywhere.
Using trains seems sensible except with 2 kids and lots of luggage, cars seem far more convenient.
Any advice much appreciated.
