Wondering if a pinhole wouldn't be rather difficult to detect with magnafluxing? Cracks show up easily but not sure if there would be a recognizable pattern with a round dot. I farm the magging out so no experience with it.
Way back in my life I worked for a pump manufacturer. Pinholes were a pretty common experience in the castings and these were new pieces so wall thickness wasn't part of the problem. All it takes is a void (glorified little air pocket) close to the finished surface or casting debris. Either of these will lead to an eventual failure but difficult to find beforehand.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
