this is from an old personal email to me which I printed off for my own use as I thought it incredibly useful... I don't think sender will mind me adding - I've been trying to work out how much access I'll have inside to clean things up, but also how many things need to be on the "absolutely double checked" list so you don't need to have to split the joint!
"Re Threebond, I applied it in a 2-3mm bead around all the openings (not just around the outside) and let the assembly of the joint squish it where it wanted to go. Keep it at a respectful distance from internal edges to help avoid bits coming off into the sump.
It has a 1-hour 'open' time so there's no particular rush. It probably wouldn't hurt to spread it with a finger or a lolly stick but make sure you have coverage. I did not use gaskets, but then I have a block spacer plate so different from most A7 engines. I would happily leave them out but I'd do a dry assembly first and check the pistons don't come up too high without a gasket in place. The [racers] set a minimum 20 thou clearance to the cylinder head to allow for crank whip on a 2-bearing engine."
