(Bedford 28hp) I've got a water leak from the thread of the main drain cock from the block. Too much for me to ignore. I'm conscious that this is a bit of old cast metal and I'm reluctant to lean too heavily on it with a spanner for fear of breaking it, as at first swing it feels very solid - despite the fact it is leaking! Which route - give it a damn good external mechanical and chemical clean and then apply something to bung it up, or further soak it in penetrating oil for another week and then have another swing? I did think of running it to get the whole lot hot and then cooling the tap with cold water soaked rags to help break the seal. Opinions /suggestions invited.
