There are three parts to this blog now, the rest of the story will follow.
Is this 998cc Hillman Imp alloy block scrap, lets find out!
To date I have first milled the excess welds off the blog using a milling cutter and special jig (easy to make) then finding that the Timing Chain Cover was higher than the block, revised the jig and then milled that away. This now means I can re use that jig for the same purpose at any time later.
The re fitting of the steel 998cc liners went to plan, I devised a method of removing the alloy that was stopping the liners fitting, the next morning it was cooler than the previous afternoon when I had re fitted the liners and I found the liners would not come out again. I placed the block outside in the morning sun, when the block had warmed up the liners would come out. So even using my hands on method I was seeing a reasonable tollerence fit.
These methods you can do yourself, you will need a decent electric router and a drill, plus some machine tools you can buy easy enough. More on the subject later.
