UV dye ?

[MMeier]

All that is needed is a black light to pick up on the dye, correct? Trying to figure out if its the mighty Cummins crying I'm beating it , or my recently redone 6 speed leaking. Have oil of some sort coming out of the opening on bottom side of 6 speed.

It should work. There are also dyes that work with infrared lights only also,so make sure it is a black light dye. Also find out what color it will show up as under light. some oils have additives that will glow under the light so you should know what color your looking for.
