Question

Quizplus · Accepted Answer

Magnaflux is a magnetic particle inspection method used for detecting cracks and defects in ferrous metals, not suitable for non-magnetic materials like aluminum. Bead blasting, while used for cleaning, is not the preferred method for OHC heads due to the risk of beads getting lodged in oil passages or other critical areas, potentially causing damage.
