I don't see them as bodges :scratch: A bodge is something that you do with no intention of putting it right when time or parts allow :scratch: What you you would be doing is a temporary repair :thumbup:
That's the way I was taught during my early years of keeping machinery running :loco:
David Jupp:
Pity about the side bore! - maybe a groove and cross drill in an extended fitting?
Manifold block - though not cheap, getting a block made (in steel?) by somebody that routinely makes manifolds might not be too horrendous. Where possible they will adapt standard general purpose (off the shelf) manifold blocks to keep the cost down, you might be lucky with any critical dimensions of the block....
I'm sure you will find a way.
awemawson:
If I manage to escape from family commitments I'm going to make that straddling 'bandage' today. Top piece is a simple plate with holes for the bolts. Lower one needs rebates to accommodate the three sticking out blanking plugs, the four tapped holes for the mounting bolts.
mattinker:
I hope I'm wrong, but I can't see your straddling block working. Although you've stemmed the flow, the leak will eventually get up to working pressure. If your strap is very strong and you machine a groove as Stuart suggests in both the strap and the block, you might get sealing from the outward pressure pushing the "o" ring into the joint.
Now that you've shown exactly where the leak is, you've got below it with the extended fitting, how about sleeving as well? I doubt that you have room to put an "O" ring at the bottom of the hole were it would do most good!
More photos of the block once it's out please!
Frustrated for you, regards Matthew

Matthew,
I've decided to bite the bullet and buy a new block, as I agree the fault can only get worse. However, I've made up the straddling clamp as a temporary measure, bedded it with Devcon Titanium Putty, and lightly tightened the screws. When it's hard in the morning I will tighten them down properly.
Have some pictures - you'll notice I had to move one of the clamping bolts as it fouled a fitting. The recesses are to clear various plugs in the base of the block
