Need some tips on welding cast engine block (253). It has cracked at the 2 centre head bolts closest to the valley, the threaded cast has cracked right off and i have to weld it back on but i only have an Arc.
Hoping i can just heat the area and weld, any tips would be good.
Can post pics tomorrow.
Oh and engine is still in the car

Re: Welding cast engine block
If you mean the bosses that are cast in a lifter valley have broken off this is common , they are only supposed to be torqued to a much lower tension. Late Holden V8's (VN onwards) do not even have these bolt holes drilled, They are not used at all. Go ahead and just put the heads back on and don't use those bolts.6.5 rangie wrote:Need some tips on welding cast engine block (253).
