I was removing my welsh plugs (maybe they are called freeze plugs in the US?) and I think I hit one a bit too hard when I was taking it out. There is a little pipe that comes out from where the cylinder walls meet, it comes out and then goes up to the top of the block....anyway, I actually think I broke it at the top. Is my block screwed? What was that pipe for ? I dont think all of the cylinder walls had the pipe coming out from between them, just a couple.

Cheers

Behind which plug are you talking?

On the exhaust/intake side, I think about the second plug from the front

If your talking about a 1/4 inch (3mm) "tube". It's not really a tube. It's a U shaped rod. They are placed between the cylinders. They are either for alignment or cooling I don't really know. Your block is fine.:classic:
