I have a new motor and I have a small oil leak but I cant pinpoint it. It's somewhere at the front of the motor and I know it's not the pan gasket because I already replaced it. I'm thinking it's the crankshaft / balancer seal but I'm not positive. Whats available to help me locate this small leak? It will only leak 3 drops after highway driving. Any other time it's dry, but it's slung everywhere underneath and it's just enough to mess up the driveway. Is there a product that will make the oil glow under a blackight or something along those lines? Any suggestions?

Thanks.
