I thought it was but there must be some crazy air turbulence in the engine compartment at speed, with no inner fenders, and a hole in the hood. Dyed the oil and it was actually leaking from the oil pressure gauge line and fitting. The original oil flows blue with a black light. With the dye it glows yellow...makes it really nice. The one pic is the blue puddle of oil and you can see the yellow dyed oil as well.
