400 oil leak
At Lotus Engineering, I was involved in the development of the LT5 V8 engine for the Chevrolet ZR1 car. GM Chevrolet were fanatical about the oil-tightness of their engines . Dripping of oil on a driveway was seen as a heinous crime. Mercury Marine, who manufactured the production LT5 engines, used Fluorescent Leak Detection as part of their pre-delivery engine tests. This uses a U/V lamp with a fluorescent dye in the oil to detect the smallest leak. Mercury were adamant that the dye was harmless to the performance of the oil, and the technique was approved by GM-but quite difficult to get rid of all traces of the dye as I recall.
And, of course, you may well wind up tracing leaks EVERYWHERE!
