Tig weldded up the head I cut off last night. When I faced and turned it to cut the chamber and seal area, full of porosity. Have done a lot of aluminum tig over the years and if theres no indication of that during welding, it usually comes from hydrogen dissolved into the aluminum and precipitating out as the temp drops during solidification. I machined it all off, cleaned up the back side, checked everything, did a test beqd on so.e 6061 and hit it again. Same *s-word. I think its in the china cast. I have welded some alloy wheels that behave the same way.
New plan. Sacrifice another jug to the chainsaw gods and skip the welding.
Ps, wasnt intended to be pretty. Was intended to look like your clapped out butthole
