Question to people who have vapor honed their engine

<< < (3/4) > >>

And the bottom end…

alexdecker:
Oh, and a real quick one here. I cleaned all of it a few weeks back, and can see some very light surface rust has formed on the piston walls and the valve guides. Should I be worried about this? I am honing the cylinders, and when cleaning the combustion chambers, have a feeling that the valve guides will get cleaned as well. It is only three weeks since I cleaned it, and it has been stored in a dry place, so the surface rust must have formed from drying from the cleaning.

Also, its all getting vapor blasted on friday. But will take steps, if this is bad. Could put some oil on them or something like that?

Dont forget the holes at the oil filter and oil pump plus the gallery where the blanking plug does behind the generator cover

The 2 holes you've marked on the gearbox bearing areas are blank holes for the dowels which locate the bearings. A quick blow with an air gun will clear those I reckon, no need to blank them.

I actually figured those passages were so big, that I could clean them rather easily, and maybe didn't need to cover them up at all. Shone a light through them, and they seem like there wouldn't be anything that would hide too well in there? Am I mistaken in that?
