I have almost completed the sump today
Taken a few mm from the alloy one .... Bolted it to the block to do the Tig welding .... Thanks for that tip mike, it soaked up the heat like a good un, would have had some distortion had I not.
Steve your dead right .... As far as cast alloy goes, I have never seen a casting with quite so many air pockets !!
Tig welds OK but trys the old patience a tad .... A tiny bit too much current & it's gone .... I guess about normal for this type of brittle casting

The standard BOC 5356 alloy tig filler rod seems to take just fine
I'll try to get some more photos posted tomorrow once I have it all done .
