This is from a vendor who specializes in Packard Parts. What say you? Thanks.


I worked my way through college as an employee of Magnaflux Corp and used a number of NDT methods to inspect auto parts, aircraft parts, underground pipelines, nuclear power plants. Of all our methods you CANNOT test aluminum using magnaflux - it requires the part to be magnetized.

Ask the vendor what SPECIFIC NDT method was used to inspect the head. If he says X-ray, then good. If we says Zyglow Penetrant, then good. But if he sticks with saying it was magnetized, then go to the nearest window and look for a star rising in the east for it would be another miracle.
