Just got block back from machine shop. Looked in the water jackets and noticed some heavy rust spots starting to flake. Is there a good removal method?
People have recommended different acids and dish detergents to cycle through the block. Have an external electric pump I can use to cycle the fluid. Was thinking of flushing into a bucket through bypass pipes with a screen/filter? Not sure how effective it will be without blocking off heads and water pump?
