What are these?
Sorry if this is an obvious question...... Noticed this hole in the block today, not noticed it before as it’s a recent replacement. Checked my old block and there were 4 but siliconed up which is why I have never noticed them before. Question is what are they for and should I silicone or just leave them? Defender 300tdi.
Thanks

Redundant holes from the drilling of oilways/waterways etc. I believe.
