How do the Irontite plugs work?
CIWS weld blocks for a living, they are one of two maybe three companies in the UK certified to weld Wartsila blocks.Thanks for your replies chaps, Welding is out cos it's a block, so way too chancy.
I'm having a go as there's nothing to loose, it's a rebuilt 1930s engine that then developed cracks and has been left standing for long periods, only ran occasionally. It ran ok but compressions were down so I took the head off, then almost wish I hadn't!

Rusty ring marks in the bores but a hone and new rings should do the job ok, there's no ring ridges at all.
The best stitching video I've found is this one, lots of tips and detail, 2 parts to it:

Very ingenious thanksThe document below is not well described on their website (they call it 'crack detection procedures'), but I think what you are asking is about page 7:
Is anything leaking at the cracks?
That's a fairly low compression side valve block, if the cracks aren't active or growing then it might run like that for ages, presuming you aren't commuting daily in it.
What is the block from ?
I see the suspect cracks and the repair
but I would want to clean that up properly before I ventured an opinion.
Yes, if it's leaking at the crack, it needs a repair. Welding.
It's an approved option...Drop an LS motor in it.
Wrong group?
With Fluid Weld, which bailed me out of a ridiculously tight corner last year....Nope, stitching.
