General update for those following.
Well we welded the engine up again, cracks were quite bad.
Clean everything and re-assemble, do a test fire up in the shed on Sunday, and guess what , more water again. The cracks are just propigating from the welds , even with good preheat in the block. So , pull the entire thing apart, clean it and start again.
This time Ian has run over the entire surface from deck to lifter bores the entire length of the block. Spitting and carrying on when the weld puddle went over thin spots, cracks, porosity, casting impurities etc etc , but we are now sure that there are no thin spots or porous spots. Back on the mill again this weekend to clearence again for the lifters, the lifter bores need a hone as they have tighten up with the welding, and will pressure test before assembly again. A whole day, bottle of gas and 1/2 box welding rods , the bl$%dy thing better not leak this time otherewise I am going to fill the f#$%ing thing and run water in the heads only.
All good fun, not!! Block looks worse that a 20 year old ex fuel hemi inside it has that many welds on it. Cant see it with the manifold on so only we will know.
Post an update as soon as we get some positive news.
