Lumiweld water jacket repair

I don't see a good reason why it won't work, and since I've got three cylinder heads here just in case. Lumiweld rods have a melting point of 780F, and are an aluminum-zinc eutectic alloy. It is slightly harder than the base aluminum alloy.

 

One needs chamber welding and valve seats, plus a port/chamber cleanup. Water jackets are in perfect shape, and the head has 30K on it. Obviously, Lumiweld won't work here.

 

Two has drilled out exhaust valve guides stuck in the head, les than 1mm thick. Still stuck in head. Needs intake valve seats and new valve guides, plus a little work on the water jacket. The trapezoid hole behind #6, one of the small holes between #3 and #4, and the headbolt sized hole in front of #1.

 

Three has hard steel seats installed, no valve guide issues, but has serious water jacket damage in the big trapezoid shaped hole behind #6, one of the small holes between #3 and #4, and the headbolt sized hole by #1. The damaged areas have been cleaned spotless with a die grinder and sanding wrap.

 

I'll document the process, and we'll see if it works out.
