Wanting to find out on M103 where oil is leaking from. It's quite shiny on the front of the motor, but doesn't show any drips. I see drips on the hoses down below however. Before I start doing any repairs, I wanted to know exactly what all is leaking. I have heard of using die in the motor oil to check with an ultraviolet light. Wanted to ask if anyone is familiar with doing this, and how hard or effective it might be?
