I have removed the oil gallery plugs (x4) from the block during my rebuild. I am now about to install back in new oil gallery plugs (12G3503 solid type from minisport).
They seem pretty tight. I was planning on just hammering them in with a punch. Is this ok or should they be pressed in? Or should I get the non-solid 12G3503 brass from minispares, or just tap the holes m14x1.5 and install grub screws?
Cheers
