I can see it twisting right into the water jacket void viewing from above with head off.
I tried wellseal but it seemed too thin, so used my new tube of Fernox LS-X which is a bit silicon-y out of the tube, and wound it into that.
Whether that will be solid enough on setting I'm not sure.
I don't want to disassemble the block at present or drill it in its present position, as I can see it will need complete overhaul at some point but want to get a few more miles testing in. At present, I seem to have a lot of parts on the garage floor... and I seen no sense in disturbing studs that are sound even if they are the wrong length.
What about JBweld? - does that create watertight seal around a stud as well having structural rigidity? And would it form its own thread if the stud were to be unscrewed at some point?
I know its bodgery, but I just want temporary reliability...
Jon, if it's just a matter of short-term running I would use hermetite to stem any dribbles and go easy when tightening it. You can always drain the rad between runs. I wouldn't use epoxy.
Incidentally I carefully trim all my manifold studs / bolts so they are fully engaged but don't obstruct the water jacket.
