we were discussing the merits of it at work today and it's apples and oranges.
Obviously a large leak would not require a light to see it, a tiny seeping leak may be too minor to even worry about under normal circumstances. So where does the light fit in?
Not trying to to knock the idea, just curious as to the uses and results.
The die seems to start showing after five minutes or less of running
the 540.
It shows up as a light blue colour on the engine. It sort of takes the guess work out of finding a leak cause it shows you where fresh oil leaks are right away before you can actually see the oil running.
I tried a snap on pencil light. not a true UV. Turbine oil is floresent as a byproduct of design.I find it invalueable in the quest for a dry engine.Used it to isolate the component seal vs split line leaks also.never used on pistons.but dyes are available for prestone and oils also.
Just a thought that may save you some money but did you ever consider cleaning the area and just using some developer and the Mark I eyeball to find a leak??
Why spend all this money on something that is not necessary??
